| 摘要 |
Electrochemical generator capable of being recharged in the solid state, employing polymeric electrolytes and a cathode, consisting of organic materials consisting essentially of polymers containing -S-S- bonds capable of being reduced by chain scission and reoxidised in the solid state by a mechanism of duplicative oxidation of the dianions derived from the thiols to re-form the polysulphide chains. The good kinetics and the electrochemical reversibility of this electrode are imparted by the presence of a conjugation mechanism which makes it possible to delocalise the charges carried by the sulphur atoms onto the neighbouring nitrogen atoms. <IMAGE> |
