Abstract

Polymer based amorphous compositions are melt extruded in the form of thin films, directly on the positive electrode of an all solid lithium battery. This procedure has many advantages as compared to the procedure using a solvent (rapidity, cost, quality of the interface, no problems with recycling and environment).
