METHOD FOR PREPARING ELECTROLYTE FOR Li/SO STORAGE BATTERY Russian patent published in 2005 - IPC

FIELD: electrical engineering.

SUBSTANCE: novelty is that added to electrolyte solution LiAlCl₄ · nSO₂ (n = 3 to 9) doped with molecular bromine in the amount of 0.2 to 0.5 mass percent which is commonly used for Li/SO₂ accumulators is 1- 2 M solution of LiAlCl₄ in SOCL₂ pre-saturated with 5 - 25 mass percent of SO₂; concentration of solution LiAlCl₄ in SOCL₂ in electrolyte amounts to 10 - 30 mass percent. Proposed method for electrolyte preparation provides for enhancing storage battery capacity by 1.5 to 1.8 times.

EFFECT: enhanced battery capacity.
