<p>A method of making a laminated multi-layer electrochemical cell device structure comprising positive and negative electrode layer members (12, 18) of a polymeric matrix composition, having a microporous polyolefin membrane separator member (16) therebetween, wherein the membrane includes a polymer coating layer. The separator is treated to provide a coating of a plasticizer for the polymer coating layer. The electrode and separator members are then assembled and laminated at a compressive force and temperature at which the pasticizer film softens the polymer coating of the separator member to sufficiently establish a strong interfacial bond with the matrix polymers of the electrode members, and thereby form a unitary cell structure. Alternatively, the plasticizer is a component of the electrode polymer matrix composition. In either embodiment, the plasticizer subsequently volatilizes from the structure to further strengthen the interfacial bond.</p> |
