Title: FLEXIBLE THIN-FILMS FOR BATTERY ELECTRODES
Abstract:
A composition comprising: a. An at least partially hydrolysed polyvinyl acetate component having an hydrolysation degree of at least 5%, b. A polyalkylene glycol component having a number average molecular mass Mn lower than 9000 g/mol and consisting of one or more substances selected from the group consisting of polyethylene glycol, polypropylene glycol, copolymers of ethylene glycol and propylene glycol, and their derivatives, c. a positive or negative electrode active component, and d. a conductive component, wherein the mass ratio between the at least partially hydrolysed polyvinyl acetate component and the positive or negative electrode active component equals at least 0.12 and at most 0.30, and wherein the mass ratio between the polyalkylene glycol component and the positive or negative electrode active component equals at least 0.012 and at most 0.10.
