A NEW-TYPE OF A ROCKING-CHAIR BATTERY FAMILY BASED ON A GRAPHITE ANODE AND A POLYMER CATHODE

The characteristics and the performance of a new type of dual intercal ation battery using low cost, efficient electrode materials is illustr ated and discussed. Typically, these batteries use a carbon-based anod e (e.g., graphite) and a polymer [e.g., poly(pyrrole)] cathode. Althou gh far from being optimized, these prototypes show good cycleability a nd an appreciable theoretical energy density. Since dual intercalation of both the lithium cations and the counteranions are involved in the electrochemical process, these new, metal-free, lithium power source systems have been termed ''dion'' batteries.
