supercapacitors

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.

Basic publications devoted to the development of theoretical ideas on the operation of the nickel-oxide electrode (NOE) in alkaline accumulators and the technologies for its production are analyzed. The urgency of this problem is due to the fact that, first, alkaline batteries are constantly being improved, and improving the operational characteristics of NOE in this situation is one of the main tasks. Second, the spectrum of practical application of nickel-oxide electrodes is constantly expanded.
