MULTI-LAYER ELECTRODE ASSEMBLY INCLUDING A GEL-FORMING POLYMER AND AN ADHESIVE RESIN MATERIAL

摘要

A multi-layer electrode assembly (128) for use in lithium-ion electrochemical cells includes a microporous polymer web (102), portions of which are coated with a gel-forming polymer material (104) and an adhesive resin material. The presence of the gel-forming polymer material reduces the amount of time required to achieve uniform electrolyte distribution throughout the lithium-ion battery, and the presence of the adhesive resin material promotes adhesion of the separator layer to the anode and cathode layers.
