Proven electric double-layer capacitors can replace batteries

Panasonic's acclaimed Electric Double Layer (Gold Cap) Capacitors range has been expanded with three new products. Available now from Farnell element14, the compact and lightweight EEC-EP, ER, and RG Series capacitors offer high volumetric efficiency and can be considered as a possible alternative to secondary batteries. Unlike batteries, the capacitors do not rely on a chemical reaction to produce electric current: they are storage cells that function on the absorption / release reaction of ions. There is no limit to the number of charge and discharge cycles that they can sustain and they do not need a charging circuit. Repeated rapid charge and discharge cycles are acceptable, says the company. Typical applications include automotive safety, infotainment, comfort accessories, PCs, industrial and infrastructure, smart meters, home appliances, medical equipment, lighting and more.
