Super Capacitors

Supercapacitors are also called ultracapacitors, double-layer capacitors, electro-chemical double layer (EDLCs) and pseudocapacitors.  Whatever you call them, Illinois Capacitor likely has what you need.  Their storage capacity is incredible.  This is a real game changer for many engineers.  Now you can use a supercap to extend the life of or even replace a battery.
