Today, supercapacitors are being developed as an alternative to batteries, particularly for use in braking systems and in start-stop hybrids. But to be an attractive, all-around alternative to batteries, capacitors must evolve to handle higher power (by a factor of two or three) and have much longer shelf and cycle life than batteries.
Capacitors can be discharged very rapidly when needed, allowing them to deliver power quickly, and they do not degrade with repeated charge-discharge cycles, giving them much longer lifespans than batteries. However, capacitors generally have much lower energy densities than batteries, meaning they can store less energy per unit …
