POLYMER MATRIX OF LITHIUM-ION ACCUMULATOR ELECTROLYTE AND PRODUCTION METHOD THEREOF |
摘要 |
FIELD: chemistry. ^ SUBSTANCE: polymer matrix is obtained by dissolving a copolymer of trifluorochloroethylene and vinylidene fluoride with molecular weight from 10000 to 500000 in an organic solvent with addition of a polyethylene glycol acrylate copolymer grafted thereto, having molecular weight from 100 to 3000, taken in weight ratio from 1:0.5 to 1:2.0 respectively. The polymer matrix of the gel-electrolyte contains a substance responsible for transporting alkali metal ions (for example lithium). The method of producing the polymer matrix of the gel-electrolyte of a lithium-ion electrolyte involves dissolving a copolymer of trifluorochloroethylene and vinylidene fluoride and a copolymer of polyethylene glycol acrylate in an organic solvent. A base or alkali metal and a catalyst are added to the obtained mixture and grafting is carried out. The reaction temperature ranges from 0 to 90C. ^ EFFECT: obtaining a polymer matrix which serves as the basis for the gel-polymer electrolyte of a lithium-ion accumulator, has high stable mechanical strength and adhesion to electrodes and provides high ion conductivity of the electrolyte. ^ 3 cl, 1 tbl |
