A safe, fast-charge, two-volt lithium/polymer cathode ‘AA’-size cell with a greater than 250 Wh kg−1 energy density

Research and development of organo-sulfur polymer composite cathodes has produced a family of materials which are electroactive and rechargeable in non-aqueous systems. This paper describes the latest improvements in the performance of AA-size cells and indicates directions to be taken for further development. Applications-oriented performance characteristics (including high-rate charge and GSM pulse discharge) of AA-size cells are described. Initial Regulatory Agency abuse tests are outlined.
