FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, particularly to polymer electrolyte with high ionic conductivity that contains copolymer of ethylene unsaturated compound and carbon monoxide, to method of its production and electrochemical element made thereof. Proposed electrolyte comprises polymer material and electrolyte salt, or polymer material, solvent and electrolyte salt wherein copolymer made up of 50% to 90% molar of ethylene unsaturated compound and 1% to 50% molar of carbon monoxide makes from 66.7 to 100 % by weight of this polymer material. Method is described to produce such polymer electrolyte and electrochemical device made thereof.
EFFECT: high ionic conductivity and reliability of operation of electrochemical elements operated at over 100 V.
