Batteries alone cannot do it all.
Most modern-day applications can benefit from the use of both batteries and ultracapacitors. “Ultracapacitors, or supercapacitors as they’re sometimes called, make batteries better” is how we say it at Maxwell.
You wouldn’t choose to drive a nail with a screwdriver, so why choose to supply high power to an application with a battery? Sure, if you had a big enough screwdriver, you could probably drive that nail with it. But you wouldn’t want to pay for such a screwdriver and likewise, you wouldn’t want to haul it around in your tool belt.
Maxwell has been approached by a number of battery makers that realize their batteries alone cannot optimally solve the world’s energy storage and power delivery problems. Batteries are great solutions, but are not perfect. They have short lifetimes, don’t perform well at low temperatures, and, most importantly, don’t have strong power performance. You can’t re-invent physics.
The best solution may not be exclusively one solution; ultracapacitors and batteries together can best solve the problems facing society in the field of energy storage. Together, the technologies are stronger than either one alone, and together, ultracapacitor and battery companies are stronger than either alone.
So let’s get on with problem solving as a team in a collaborative effort and improve the world of energy storage and power delivery.
