Comparative results of capacity renewal of sealed nickel-cadmium batteries with asymmetric and direct currents after their long-term storage are represented. Capacity renewal with asymmetric current was carried out in an accelerated manner at average value of the charging current equal to 0,25C_rated. Capacity renewal with direct current was carried out at average value of the charging current equal to 0,1C_rated in accordance with Technical Conditions.

The results of nickel cadmium accumulators (NCA) formation with the asymmetric and constant currents are represented. Accumulators formation with the asymmetric current allowed to reduce one-half the time of technological cycle of placing these accumulators in service, comparing with the constant current mode, with maintenance of their operational characteristics. Comparative characteristics of NCA operational parameters are given.

In this review electrochemical and structural data for the electrodes made of certain of perspective materials for supercapacitors are considered. These electrodes were made on the basis of high-dispersed carbon materials.
