Battery with polymer electrode: Battery with polymer electrode. (Hitachi, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59119682 A2 10 Jul 1984 Showa, 9 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01M010-40. APPLICATION: JP 82-226560 27 Dec 1982. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 38 A battery having anode and/or cathode composed of polymer having conjugated double bonds in main chain, which may be doped, uses an electrolyte salt MN(SiR3)2 (R = C1-15 alkyl, C6-15 aryl; M = alkali metal) dissolved in nonpolar solvent. The use of the salt provides high energy d., stable voltage, reduced self-discharge, and long cycle life. Thus, C2H2 was polymd. at -78° by using Ti(OBu)4 and Et3Al catalysts. The product with fibril structure was dried to obtain red-purple film, which was cut to size and attached to Pt wire collector. A battery having 2 polyacetylene [25067-58-7] electrodes and M LiN(SiMe3)2 [4039-32-1] in hexane as electrolyte was constructed, and charged to 6% doping. Charge-discharge cycles were repeated 421 times.
