Abstract:
A process for preparing solid lithium electrochemical generators comprising the steps of:(a) preparing a battery laminate comprising a lithium anode film, a polymer electrolyte film, a cathode film and a current collector film; (b) cutting said battery laminate with a mechanical cutting means comprising means selected from the group consisting of solids, liquids, and mixtures thereof, thereby exposing a cut edge of said battery laminate; and (c) applying a reactive fluid selected from the group consisting of water, alcohol, halogenated compounds, sulfured compounds and oxygenated compounds onto said cut edge to electrically insulate an exposed edge of said lithium anode film from an exposed edge of said cathode film so as to prevent electrical short circuits between said anode film and said cathode film.
