摘要

Lithium-polymer-system based high duty batteries (I) comprises lithium-intercalable titanate (A) as negative electrode and lithium-intercalable iron phosphate (A1) as positive electrode. Independent claims are also included for: (1) high speed lithium-polymer-energy storage (having an active cathode mass, an active anode mass and an arrester, where the active electrode masses are mixed and/or mixed intensively with lead salt and/or solvent, and then extruded and separately laminated on the arrester material to electrodes) comprising forming the active electrode masses following the intensive mixing and before extruding with polymer binder to active substance-concentrated; (2) a method for preparing lithium-polymer batteries by means of a arrester, electrode mass for cathode and anode and separator comprising compound system comprising subjecting the arrester foil to extrusion with electrode mass and subsequently joining with separator material, which is in contact with the electrode mass at the electrode substrate side; and (3) lithium polymer high speed energy storage obtained by the method.
