FIELD: electricity.
SUBSTANCE: invention relates to chemical current sources, particularly to compositions of electrolytes, used in lead-acid accumulators, and can be used for production of accumulator batteries for electric vehicles, automobiles with combined power plant, as well as for vehicles with traditional petrol engine. Electrolyte contains, wt %: borate methylphosphite 0.6-0.8, perfluoropolyether acids flouranhydrides with molecular weight of 800-1,000 0.1-0.3, Chitosan 0.1-0.3, sulphuric acid 20.0-30.0, and distilled water up to 100.
EFFECT: technical result is improved electrical and operating characteristics of lead accumulator, as well as increasing its service life.
