FIELD: electricity.
SUBSTANCE: invention relates to the field of electric engineering, in particular to polymer electrolyte and electrochemical device using polymer electrolyte. Problem has been solved due to application of polymer electrolyte (5), which has ketone carbonyl group, where mass fraction of ketone carbonyl group makes from 15 to 50 % (wt) relative to mass of polymer material, and mass fraction of electrolyte salt relative to total mass of polymer material and electrolyte salt makes from 5 to 75% (wt).
EFFECT: increased ion conductivity and reliability of power supply source.
