FIELD: chemistry.
SUBSTANCE: invention relates to chemical current sources. Chemical rechargeable current source comprises alternating layers of cathode, separator and flat anode in cross section. Anode is made from aluminium-graphene composite material containing from 99 to 99.9 wt. % of aluminium containing not more than 0.1 wt. % of impurities and graphene is the balance. Chemical current source comprises electrolyte filling free space between anode and cathode. Cathode is flat and contains a metal base coated on both sides with layers of carbon.
EFFECT: higher aluminium-ion conductivity in chemical sources of current and higher resistance of anode to aggressive medium.
