<p>A rechargeable solid polymer lithium ion battery cell assembly including a positive electrode, a negative electrode, and a separator membrane in which at least one of the positive electrode, the negative electrode and the separator includes a cross-linkable polymer free from cross-linking additives and cross-linked by exposing the assembly to actinic radiation prior to providing an electrolyte to the assembly is provided. A method is provided for making the solid polymer lithium ion battery cell assembly and the individual cell components by providing a cross-linkable polymer to at least one of the cell components, exposing the component to actinic radiation, and cross-linking the polymer. This invention can prevent degradation of the cell electrode and separator structures in a polymer electrolyte lithium ion cell and reduces cell problems related to high temperature failure and reduced useful battery life.</p> |
