PROCESS OF PREPARATION OF ELECTROLYTE SOLUTION FOR Li/SO CHEMICAL SOURCE OF ELECTRIC ENERGY Russian patent published in 2001 - IPC

FIELD: electrical engineering. SUBSTANCE: in correspondence with invention traditional solution of electrolyte LiALCl₄·3SO₂ is injected with molecular bromine in the amount of 0.2 to 0.5 per cent by mass and saturation with gaseous SO₂ is conducted at temperature from 0 to minus 5 C under excessive pressure from 1.5 to 5.0 atm. Prepared solution is cured in the course 72 to 86 h at room temperature. Proposed process makes it feasible to raise discharge capacity of chemical source of electric energy by factor of 1.5-1.8. EFFECT: raised discharge capacity of chemical source of electric energy. 4 tbl
