BATTERY ELECTRODES WITH ENLARGED SURFACES AND METHOD FOR PRODUCTION THEREOF

摘要

A method for the production of battery electrodes and battery electrodes produced by said method are disclosed. Said method comprises the production of compositions for the electrode masses for cathode and anode mass and optionally a separator mass and the extrusion of the electrode masses to form the anode or cathode from the electrode masses. The above is characterised in that the electrode mass comprises isocyanate and an aqueous dispersion of a polymer binder, which react together to form porous structures. Said method provides extremely elastic and yet mechanically stable battery electrodes which can be applied in lithium secondary batteries.
