FIELD: re-chargeable chemical sources of electric energy safe in operation. SUBSTANCE: source includes anode made of metal lithium or lithium containing alloy, electrolyte, separator, cathode and membrane produced from nickel foil having thickness 10.0-250.0 ??m, porosity 10-60% and pore size 1.0-50.0 ??m. At least one side of nickel foil may have ultraporous nickel layer having porosity up 85%, thickness 5.0-50.0 ??m and pore size 0.1-10.0 ??m. Nickel foil can have electric contact with cathode. EFFECT: prolonged service life of chemical source. 2 clr |
