What’s Driving Interest for Supercapacitors?

[Editor's note: In this article we welcome guest blogger Jason Lee, Global Product Manager of Eaton’s Electronic Division.]

Why are so many enamored with supercapacitors?

Chances are you’ve heard mention of supercapacitors if you haven’t yet implemented them in a system design. That’s because when components experience a 30 percent compound annual growth rate, it is usually driven by game-changing advantages.

But what exactly is the potential that supercapacitors promise? As energy storage devices, they offer:

  • High power density
  • High durability and long life
    • 500,000 to 1 million charge/discharge cycles without penalties for deep discharge or high currents
    • Up to 20 years' lifetime for backup/UPS applications
  • Highly efficient energy transfer, typically greater than 98 percent
  • Cost-effective operation in terms of watt-hour cycles or watt-hour years
  • Stable performance over a large temperature range
  • A green alternative to batteries

Not only are the technical advantages compelling, but evidence suggests that capabilities are evolving rapidly, especially compared to traditional capacitors and batteries. Additionally, costs are coming down, according to market research firm IDTechEx, even as the number of application areas continue to grow.

While battery backup and consumer electronics represent significant share in supercapacitor applications, the large majority of adoptions are for traction motors such as electrically powered rail vehicles, electric locomotives, and trolley buses, as well as vehicles with electric transmission systems such as diesel-electric buses and stop-start cars. Additionally, mobile phones, energy harvesting, renewable energy, and other products of the future will enable this market to grow to more than $11 billion in 10 years, according to IDTechEx.

To be sure, supercapacitors, or ultracapacitors as they are often known and, technically, electrochemical double layer capacitors, are used for energy storage and are not filter components. They are electronic charge accumulators with extreme capacitor-plate-specific area and atomic scale charge separation distance. Unlike batteries, no chemical reactions occur within supercapacitors, and they only store and release energy. Think of them as rechargeable batteries on steroids. While they hold relatively little energy compared to a battery, they can release their energy very quickly. Using another analogy, supercapacitors are like a sprinter with quick bursts who, after short rest, can run again; a battery, on the other hand, is more like a marathon runner.

How do supercapacitors differ from other types of capacitors? Capacitance is measured in surface area over thickness, and supercaps have thickness of greater or less than one nanometer. Supercapacitors have a carbon powder surface area up to 3,000m2 /g. The supercapacitor stores electrons. No reactions take place, so electric charge is available immediately as electrical power. When delivering power, the voltage drops in response to the supercapacitor shedding its storage charge, just like any other capacitor. Due to the very high surface area and molecular scale spacing between capacitor plates, the reaction time is slower than other types of capacitors, but all of the same electrical properties apply.

Supercapacitors have greater power and energy density compared to batteries. It takes 10 hours for a lead-acid battery to deliver a charge produced by a chemical reaction. A supercapacitor could deliver the same charge in as little as 1 second from devices that are much lighter in weight.

Supercapacitors can deliver power at temperatures as low as -40°C as opposed to many batteries, which usually can only operate down to -20°C. They are reliable and predictable in delivering power in conditions up to 85°C whereas batteries are only reliable in conditions up to 60°C.

One of the greatest advantages for supercapacitors is cycle life, because cells can be charged and discharged more than 500,000 times compared to batteries that start to degrade between 300 and 10,000 cycles. Of course, there are several different battery types with varying cycle capabilities. Lead-acid batteries have up to 3,000 cycles; nickel-cadmium has up to 10,000 load cycles; and lithium-ion has up to 10,000 load cycles. Supercapacitors, by comparison, have up to more than 500,000 load cycles.

Supercapacitors can endure from five to 20 years in situations where batteries last from half a year up to only five years.

Additionally, supercapacitors, which are often used in conjunction with batteries, offer various safety advantages, such as the lack of heavy metals used in construction. They meet a variety of environmental and safety standards stipulated by RoHS, SVHC, and UL.

To summarize, the industry’s admiration with supercapacitors is multifaceted. They deliver high power density, high durability and reliability over a greater operating temperature range, and long life in comparison to batteries. Although they are not primary power sources, they offer immense advantages is in terms of safety, cost, weight, and performance for a variety of electronic and electrical systems.

    Alternative battery including supercapacitors, needs to consider the cell damage during the many cycle of charging and discharging. This is why auto manufacture only warrantees battery pack for 7 years or above.  This issue might be related to electronic system of charging cycle and cell itself. Cycle time of  500,000 could be changed depending on testing condition.

    I read of an application a while back where Super Capacitors were used in a portable jump starter for your car battery.  You start with a small, portable precharged LiION battery pack, transfer charge to a Super Capacitor, then discharge the super capacitor while trying to start your car.  That seems like a clever application rather than trying to find a friend or call AAA.

    Are you aware or have you considered Advanced Linear Devices SAB MOSFET, this is a new product that will balance the cell and ALD has reason to believe that it will also help manage the charge and discharge issues.

    Selection of components is very important. Also I prefer much more to develop the algorithm for cell balance during charging and discharging cycles.  Algorithm should contain the control of cell characteristic of cell in terms of analog circuit, even though there is a limitation.

    It is proven that supercapacitors are now capable of hundreds of thousands, if not millions, of charge and discharge cycles which are several orders of magnitudes greater than battery technologies.  This is what is driving the demand and adoption of supercapacitors in automotive and many other market applications that need a reliable power source.

    I agree Swatee, supercapacitors benefits many applications, from short power pulses, to thosr requiring low-power support of critical memory systems. Whether used alone or with other power sources, supercapacitors provide an excellent solution in several system configurations and high power applications- power conditioning, UPS, industrial lasers, medical equipments and hybrid vehicles.

    @Scott you're right, supercapacitors permit faster acceleration, increased range and extend battery life by freeing it from stressful high-power tasks. In addition, supercapacitors technology can now do load-leveling to extend the life of EV batteries and provide the high power essential for EV acceleration. for example, a car might use this power to burst acceleration and climb a steep hill or terrain, supercapacitors also can absorb regenerative braking energy and thus limit the otherwise very high charging current to the battery.

    All that is said is correct. I have used supercaps in some applications. However, there are drawbacks. A) They are not cheap, enough to power a micro and peripherals for a few minutes can double the cost and more. B) Assuming that all energy can be drawn from a supercap, an equivalent energy AA battery is far smaller. C) Calculate the energy draw after a month of leakage and you notice that supercaps cannot be used for long term storage.

    Select the proper use for supercaps. They have a good future ahead, maybe even to replace chemical batteries, but that future is not here yet.

  12. Michele Kinman

    Batteries and supercapacitors both have their purposes.  If you take into account the replacement cost of batteries (battery cost, disposal and labor) over the lifetime of a system, supercapacitors become very attractive.  In high cycling (charge/discharge) applications like hybrid vehicles, construction/mining and train/trolleys, the key metric is cost per watt-hour cycle.  In these cases, the high cycle life of supercapacitors makes them very cost effective versus batteries.

    The energy density statement was an error.  It should have been high energy density compared to other types of capacitors.  Energy density of supercaps is 1/100-1/10 of batteries while batteries have 1/100-1/10 the power density of supercapacitors.

    Battery or supercapacitor advantages do depend upon the application.  In short discharges (1second up 1 min) or very low power applications, supercapacitors can be more cost effective and efficient than batteries.  The cost of batteries must take into account the total cost of replacing the batteries.  Many designs use batteries and supercapacitors together to get the best of both.  They are here today.  There are millions of supercapacitors in use today in nearly every Smart Meter, in cars, in hybrid busses and in solid state drives (SSD) and flash memory servers.  But even more is expected in the next 5 years than have been used in the last 10 years.

    Automobile manufacturers of EV keep high interest in such supercapacitors infact they have developed prototypes that uses supercapacitors instead of batteries to store braking energy in order to improve driveline efficiency, I believe Mazda 6 is the one.

    Because of the high density of energy in supercapacitors, I expect it to become the main storage medium in cellphones, smart watches etc in coming years. I know the mindset is on electric vehicles, the immediate adoption before the technology matures will be mobile-based consumer electronics.

    “Additionally, mobile phones, energy harvesting, renewable energy, and other products of the future will enable this market to grow to more than $11 billion in 10 years, according to IDTechEx.”

    The available market for the smart electronic systems is rated for 2015 as 1.1 B$. In such systems the role of supercapacitors is vital and I think that this figure will increase in the coming years.

    >> Automobile manufacturers of EV keep high interest in such supercapacitors

    I expect this technology to have convergence with Memristors and we will have avalanche of energy for devices and vehicles. The only challenge today is that the gas price is going down and most of those technologies may suffer. Tesla is revising sales by 40% as people are no more running to buy hybrids and EVs. If gas price stays low, we may have a redesign in the markets and that will affect developments in some of these energy improvement technologies.

  20. samicksha
    December 19, 2014

    Mobile phones, smart watches are already on high cost, addition new energy mechanism such as supercapacitor could lead addition of $$$, also another aspect about supercapacitors is their low energy density, they can store per unit is very small, particularly when compared to batteries.

  21. etnapowers
    December 19, 2014

    “If gas price stays low, we may have a redesign in the markets and that will affect developments in some of these energy improvement technologies.”

     

    @goafrit2: I hope that the sustainable technologies development will not suffer for this phase of reduction of oil cost. I like this type of approach because the adoption of hybrid systems for automotive has the effect to reduce pollution due to reduced CO2 emissions. Moreover the renewable sources of energy like the sun energy may be utilized to supply the electronic circuitry of a car and this results in saving the batteries hence it results in a maintenance cost reduction for the owner and in a positive impact for the environment because less batteries will be trashed.

  22. etnapowers
    December 19, 2014

    @samicksha: that's a common fact for all new solutions. Initially the costs are high, but it will be cheaper as soon as the supercapacitor technology will be massively adopted by all the producers of smartphones, tablets and all the electronics objects that are becoming energy-hungry as well as the requirement of new applications and functionalities increases.

  23. etnapowers
    December 19, 2014

    “another aspect about supercapacitors is their low energy density, they can store per unit is very small, particularly when compared to batteries.”

    @samicksha: the technology of supercapacitors is relatively new and the technical features will be enhanced if the solution will become well working for smart objects (smartphones, tablets,…) having a continuous increasing demand of new applications. Moreover the supercapacitors may save the batteries and increase the autonomy of a phone or a pc, and this is really a great feature.
    I think that supercapacitors are a perfect solution for this type of application and these devices will hit the market very strongly in the near future.

    December 20, 2014

    I agree your point @etnapowers, in future yes we might see supercpacitors in Mobile phones, but as noted earlier as well, currently energy density within it is much lower than in standard Lithium-ion batteries used in cell phones.

    Samiksha, not necessary. Now a day's good Smartphones from unbranded companies with Android jelly beans are available for less than INR 6000. Even branded from Samasung and other companies are availbile for less than INR 12500 (Samsung S4 Mini)

    ” in future yes we might see supercpacitors in Mobile phones, but as noted earlier as well, currently energy density within it is much lower than in standard Lithium-ion batteries used in cell phones.”

    Samiksha, you may be true because fast power drain is a major issue with most of the smartphones. So any mechanism for extending the power durability can get a warm welcome from industry.

    “I think that supercapacitors are a perfect solution for this type of application and these devices will hit the market very strongly in the near future.”

    Etnapower, you are right; especially for mobile/portable handy devices. Power drain is a major issue with such devices, especially if you want to connect to the network. Lots of R&D is happening in power storage domain to increase its capacity.

    December 28, 2014

    @Myanalog: The need of supercapacitors  is related also to the increased mean timeframe of powering the displays that is due to multiple apps integrated in a smart object: a user is able to check his email, connect to the Internet , utilize online applications, playing offline games etc… Hence the user of a smartphone uses it for more time than the past and this require much more energy which might be stored in integrated super capacitors.

    @myanalog: I think besides that, the perceived value of the technology matters a lot along with all the other factors. You may have a very high quality product with great functionality but if the perceived value may be lower in the market for any reasons. This would render the quality and functionality useless.

Price may be an important factor in the low-feature, low-cost tier, but when it comes to the higher end of the spectrum, the quality and features make the major difference.

    Agree with you. Price is important mainly in Low and Middle segment as they produce almost same featured mobiles. Therefore, customers may look out for Price factor. 

    But when it comes to high end, as you said correctly, Quality & the features will make a difference. People are ready to pay little bit more for a High Quality, High featured products which has a Brand Value.

    If any organizaion is using High Quality materials & provide quality and unique features on their products, it is mandatory that they maintain a high percieved value for their product in the market. Otherwise, they will not be able to claim high price for their product and generally would be in loss.

    It is possible because in the time of abundance, few will worry on efficiency. If energy is cheap, investors may not put money into areas that have indirectly improved these energy storage sectors through research. Just as the sales of hybrid and EV cars are failing, no energy related sector will not be affected since this will slow the research dollars put into the sector.

    Power drain is a major issue with such devices, especially if you want to connect to the network. 

    But notice that CMOS based memory systems may remain very popular because of the low static dissipation which you referred in the comment. I am not sure supercapacitors will offer that same level of advantage. The reason we can use phones for days off charge is because most are built with CMOS which is good with not just high integration capacity but low static power loss.

  68. fasmicro

    samicksha yes it will fulfill the need gap but also it will increase the cost of the device.

    If that is the case, then it will be an issue. But if it brings more effectiveness at high cost, you then look at the cost-to-benefit ratio. It remains to be seen how anything will do better than CMOS because of the higher density of integration it provides and low static power. It is not just to have power, but how long can it be retained!

    There is big news this week – investment in energy efficiency is expected to drop. The money men think the transition to the post-oil will not be that smooth if OPEC could fight with extremely cheap oil for price to become a factor if one buys an EV or a gas vehicle. When customers see cheap gas prices, the decision to buy more energy-efficient systems may not be important.

    “But notice that CMOS based memory systems may remain very popular because of the low static dissipation which you referred in the comment. I am not sure supercapacitors will offer that same level of advantage. The reason we can use phones for days off charge is because most are built with CMOS which is good with not just high integration capacity but low static power loss.”

    Fasmicro, super capacitor is a new technology and let's wait and see how companies are going to make use of the technology.

    “Simply the technology improves. It is not just volume. Even the small players have their products improved. But the key driver may not be visible. There are what they call chipsets which Flextronics and Mediatek make. They help most phone makers especially Android OS to focus on assembling while they buy the brian of the system.”

    Goafrit2, frequent updation or enhancement can be taken place based on market requirement. If that's not happen than technology becomes obsolete within a few months/years. That's the reason we are not able to upgrade our Smartphones with new Android version 5.0

    “There is big news this week – investment in energy efficiency is expected to drop. The money men think the transition to the post-oil will not be that smooth if OPEC could fight with extremely cheap oil for price to become a factor if one buys an EV or a gas vehicle. When customers see cheap gas prices, the decision to buy more energy-efficient systems may not be important.”

    Fasmicro, you are right about the places where gasoline can be replace with storage cells. But have no connection with other places like portable devices of kind laptops, Smartphones etc

    “If that is the case, then it will be an issue. But if it brings more effectiveness at high cost, you then look at the cost-to-benefit ratio. It remains to be seen how anything will do better than CMOS because of the higher density of integration it provides and low static power. It is not just to have power, but how long can it be retained!”

    Fasmicro, the real issue how such 'cost to benefit ratio can be derived'. As an example we can have 4400mAh power bank from market for $10& $40, from different vendors. The first one is from a local vendor and the second from a reputed brand. Both functions same and have replacement warrant for a year.

    @samicksha: I think it is the normal evolution of the technology. Better objects are offered at a higher price, the key point is to keep a deep correlation between the quality and the price of the product, to satisfy the customers.

    @samicksha: you're right, but the use of the supercapacitors has an high potential, it holds promises of a dramatic increase of the autonomy of smartphones, a goal that is very challenging to reach with the  lithium batteries.

    A clear confirmation of our agreed statement is the smartphone: at the beginning it was a very expensive object, nowadays that many improvements have been performed and many models have been sold a customer could find many really good smartphones at a reasonable price.

    Table shows a general promise of Supercapacitor and Lithium-ion. It might be a little doubt that charging temperature of Lithium-ion is 0C to 45C, because Lithium-ion installed in the vehicle could be slightly different from that. In reality, it could be happen that vehicle needs to be charged in the very lower temperature.

    Yes… True and agreed. Even though there are quality limitations according to price layers, one could now find a decent Smart Phone at reasonable price.

    @Myanalog: that's correct, my statement is related to the increased time of utilization of the smartphone display, due to a wealth of possible applications for the user, and the increased dimension of the display requires a dramatically increased amount of energy, even if you use offline the smartphone or the tablet.

    “Etnapowers, the normal 2200 mAh cell power won't be sufficient for all these activities in 24 hours. At the same time there are some limitations in increasing the power of these cells too. so I hope super capacitors can be an alternative for this.”

     

    @Myanalog: I think that the supercapacitors might be very helpful to handle all the energy required for all these activities but, moreover, a smart management of the processes of the OS of the smartphone would be a very important step in the direction of an effective energy management inside modern smart objects.

    @goafrit2: your analysis is correct, I wonder only how much time this phase of low cost of oil will last. In perspective the company that invest today on sustainable technology may be favoured tomorrow , if the cost of oil will be increased.

    @goafrit2: thank you for your comment. I think that the success of the supercapacitors technology is deeply related to the success of new smartphones and tablets technologies, that require integrated capacitances with high storage capability, being high energy demanding.

    I really don't know if in the near future the price of oil will be low as it is today. I think that this is a temporary phase and I believe that not investing in renewable and sustainable technologies might present some risk for the business and, moreover, for the environment in which we all live.

    @ue2014: You're right, the quality limitations may include a assistance chain which may be not as efficient as the assistance of big brands; obviously this is not always true, and in many cases the big brands make low cost smartphones and, hence the customers are assisted by the official assistance department and generally there are no issues of quality.

    Etnapowers, even you are offline, many of the applications are working at back end. For example GPS, weather info, Local service etc are some of the back end application. It works throughout the day and consumes lots of power.

    Myanalog: you're right, that's the reason for why the developers of new smartphones have released new versions of the operating system of the smartphones and tablets to manage the background applications in order to waste less power as possible.

    >> Fasmicro, super capacitor is a new technology and let's wait and see how companies are going to make use of the technology.

    I consider this technology to be in the same category with nanotechnology with many hypes and less products in the market which has been transformative and impactful. Sure, it is still new and we will see how it plays out

    That is certainly the core reason why firms compete. There is always a changing habit from customers. We keep innovating to meet those needs. Technology has a major role to transform every aspect of our lives. I understand that those that meet those needs are rewarded with big returns.

    The driving reason for massive investment in storage and innovation in battery is not influenced by those that make phones. The car companies do most of the R&D while others benefit from the results.

    Hardware needs to improve so that we can use things like API as is done in software. Application Program Interface (API) has helped a long way to connect the different pieces on the web. When you have that level of design liberilization, you will not have to worry so much on the brand names as most will be closely similar in quality.

    For inelastic demand. There are some products like watches where the value is that it is very expensive. That is also a technology. It is not the value derived but the exclusivity. Apple uses its brand to get the same impact

    Apple deserved the right to use its brand to promote high value objects. It's a matter of image created by mean of high end devices very attractive for the customers.
