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).
Claims20
Process for coating a solid polymer electrolyte on a positive electrode of an all solid lithium battery, which comprises introducing an at least partially amorphous homopolymer, copolymer or terpolymer base composition into an extruder, extruding said composition in the form of thin film and directly depositing said thin film, at the outlet of the extruder, on a previously prepared positive electrode film.
