Abstract
The review of modern scientific and technical literature on supercapacitors produced by industrial companies is presented. The advantages of supercapacitors compared to batteries are: high power density, high cycleability, the ability to operate at extreme temperatures from –50 to +60°C, energy efficiency up to 100% and the ability to charge in a very short time. The review examines the characteristics of supercapacitors manufactured by the following companies: Maxwell Technologies (California, USA), NessCap (Republic of Korea), ApowerCap (California, USA), Skeleton Technologies (Germany, Estonia), EPCOS (Munich, Germany), Panasonic (Osaka, Japan), Fuji Heavy (Shibuya, Japan), Asahi Glass (Tokyo, Japan), ESMA (Moscow region, Russian Federation). The characteristics considered in the article include specific energy, power density, full discharge time, full charge time, discharge efficiency, the number of full cycles, rated voltage and temperature range.
