Following the development of solvent free polymer electrolytes having ambient temperature conductivities (-10_3 Scm) of the order required to operate lithium batteries (10 to 100 times more conductive than conventional amorphous polymer electrolytes) it is proposed to develop cells with lithium metal anodes and composite cathodes to enhance their commercial potential Unlike the ionophilic conventional materials the new electrolytes are a weakly ionophilic blends of a low-dimensional amphiphi is polymer and a linear ion-bridging polymer with lithium salts. It is considered that lithium ions are transported with low activation energy as aggregates of ion pairs or quadrupoles. The novelty of this approach requires that their application in lithium cells is investigated by fabricating composite cathodes for Li intercalation into transition metal oxides e.g. V205, CoO2 or Mn02. The factors to be investigated include cathode composition, particle coatings to facilitate ion transfer across the electrolyte-ceramic interface and possibly to inhibit oxidative degradation, cell design and the phenomenon of `tracking' whereby the path of least resistance is created in the polymer electrolyte close to the crystal - liquid crystal transition temperature.
