FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, specifically to fast-charge system (20) comprising fast-charge composite (60) and secondary battery (22). Fast-charge composite (60) includes cellulose separator (62), wetted by second electrolyte (64) containing third ions (94) having a positive charge, and fourth ions (96), having negative charge, which are in contact with said adjacent electrodes (32), (46) of battery (22). Fast-charge layer (30) of thermally expanded graphite is stacked with separator (62). Second electric power PFC, which can be greater than maximum charging power PMAX, is transmitted using conventional charging means and transferred as a second voltage function between fast-charge layer (30) and terminal of battery (34), (50) of adjacent electrode (32), (46), which causes migration of third ions (94) and fourth ions (96) through separator (62) in order to charge secondary battery (22).
EFFECT: prevention of short circuit in storage battery with fast-charge technical result of the invention is the composite allowing the secondary battery to accumulate a predetermined amount of electrical energy.
