Tri-laminate production, for use as basis for rechargeable polymer-lithium battery, comprises separate homogeneous mixing of anode and cathode compositions and polymer gel electrolyte and (co)extrusion

摘要

An anode composition (I), a cathode composition (II) and a polymer-gel electrolyte (III) are prepared separately as homogeneous masses in a continuous kneader or mixing system at 130-200 deg C and then extruded and combined, so that (III) forms the binder layer between (I) and (II); and (I) and (II) are provided with current collectors.
