FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to solid-state accumulator, in which reversibility of lithium metal deposition and dissolution reaction can be increased at simultaneous prevention of short-circuit occurrence. Said target is achieved by providing solid-state accumulator using lithium metal precipitation and dissolution as anode reaction, where solid-state accumulator comprises anode current collector, porous layer containing polymer, layer of solid electrolyte, layer of cathode active material and cathode current collector, in specified order, wherein electric resistance of porous layer is 1 Ohm or more and 690 Ohm or less; and porous layer thickness is 14 mcm or less.
EFFECT: technical result of the invention is prevention of short circuit during charging of accumulator with speed of 1C or more.
