Free-standing films of graphite anode and LiCoO2 cathode materials were produced using 1wt.% ultra high molecular weight polyethylene (UHMWPE) as a polymeric binder. The technique of vacuum deposition was used in order to provide the anode and cathode materials with 1μm thick layers of aluminium and copper, respectively, as current collectors. Porous separators were produced by drawing a UHMWPE film filled with inorganic particles. The anode, separator, and cathode materials were then laminated under heat and pressure to produce a single flat cell. The cells were soaked in a liquid electrolyte and sealed in aluminium laminated plastic bags. Batteries produced in this way were cycled at high rates and after 300 cycles only a slight decrease in capacity was observed. Thanks to the thin current collectors and the small amount of polymeric binder the amount of non-active material in the battery was minimised.
