FIELD: chemistry; electricity.
SUBSTANCE: invention relates to compositions based on organic high-molecular compounds, particularly to solid polymer electrolytes for lithium-ion batteries. Solid electrolyte consists of a polymer matrix filled with a solution of a lithium salt in dimethylsulfoxide (1–14 pts. wt), and the polymer matrix is a polyurethane elastomer obtained by mixing a commercially available prepolymer Adiprene 1950 based on polyester and p-phenyldiisocyanate and amine hardener 3,3-dichloro-4,4-diaminodiphenylmethane, MOCA, taken in ratio of 86:14 wt.%. Obtained solid polymer electrolyte has a conductivity of more than 1⋅10-4 S/cm at room temperature.
EFFECT: high ionic conductivity at room temperature, as well as simpler production of the polymer matrix and electrolyte.
