POLYMER ELECTROLYTE, THE USE THEREOF AND AN ELECTROCHEMICAL DEVICE CONTAINING SAID POLYMER ELECTROLYTE

摘要

The invention relates to a polymer electrolyte comprising a lithium salt component and a polymer component, wherein said polymer component comprises at least one type of polymer compound whose repeating units comprise, at least partially, groups interacting with lithium salt component ions in such a way that the lithium salt dissociation is promoted. In such a manner, the high ion conductivity of the polymer electrolyte is provided by the interaction of the polymer component with the lithium salt component ions without a liquid component, i.e. without plastisizer or solvent. The inventive polymer electrolyte is particularly suitable for an electrochemical device, in particular for a battery or a storage battery. The use of said polymer electrolyte for producing an electrochemical device, in particular a battery or a storage battery, an electrochemical device containing said polymer electrolyte and a method for increasing the ion conductivity thereof are also disclosed.
