Estimating the term…
The present invention relates to a polymer electrolyte having a lithium salt component and a polymer component, wherein the polymer component comprises at least one polymer compound, the repetitive units of which have at least partially groups which interact with the anions of the lithium salt component such that the dissociation of the lithium salt is enhanced. Thereby, a high ion conductivity of the polymer electrolyte is ensured by the interaction of the polymer component with the anions of the lithium salt component without a liquid component, i.e. without plasticizer and solvent. The polymer electrolyte according to the present invention is particularly suitable for the use in an electrochemical device, in particular in a battery and a secondary battery. Furthermore, the present invention relates to the use of the polymer electrolyte for producing an electrochemical device, in particular a battery and a secondary battery, an electrochemical device comprising the polymer electrolyte as well as a method for increasing the ion conductivity of polymer electrolytes.
Polymer electrolyte comprising a lithium salt component and a polymer component, wherein the polymer component comprises at least one polymer compound, the repetitive units of which contain at least partially groups which interact with the anions of the lithium salt component such that the dissociation of the lithium salt is enhanced, wherein these groups are an element of the polymer main chain and/or an element of side chains attached to the polymer main chain of the polymer compound.
Method for increasing the ion conductivity of a polymer electrolyte comprising a lithium salt component and a polymer component, wherein the increase in ion conductivity is effected by stabilizing interaction of the polymer component with the anions contained in the lithium salt component.
