FIELD: chemistry.
SUBSTANCE: invention relates to lithium-air accumulator, which consists of metal lithium anode located in sealed chamber filled with non-aqueous lithium-conducting electrolyte, cathode, located in cathode chamber, having access to oxygen and filled with non-aqueous lithium-conducting electrolyte. Accumulator is characterised by that cathode current collector is coated with recovered graphite oxide with carbon to oxygen ratio from 5 to 10, wherein partition wall is made of solid electrolyte conducting lithium, cathode and anode are pressed to membrane by means of piston (perforated in case of cathode) and spring. Invention also relates to method of accumulator producing.
EFFECT: use of present invention enables to achieve high specific capacitance of 6000 mAh/g of cathode material at current density of 1/100 mA/cm2, which increases battery life without charging.
