PREPARATION METHOD OF GEL ELECTROLYTE FOR LITHIUM-ION CELLS Russian patent published in 2011 - IPC H01M10/56 

FIELD: electricity.

SUBSTANCE: for preparation of electrolyte there used is mixture of dispersion of acrylate and its copolymers and organic electrolyte with non-organic lithium salt. Mixture is prepared together with ultrasound dispersion; dispersion of polyacrylate of styrene and acrylate is used as base in organic solvents at the following mixture component ratios, % (dry weight); water-free ionogenic non-organic lithium salt: 15-30; dipolar aprotonic solvent (DAS): 30-40; polyacrylate or styrene-acrylate: 30-55, at that, electrolyte is dried till residual moisture is 0.003% (dry weight).

EFFECT: increasing specific discharge capacity, decreasing ecological risk and reducing the prime cost and explosion safety.
