Conductive additive and discharge promotor mixture for reducing cell swelling in alkali metal electrochemical cells |
摘要 |
An electrode comprising acetylene black or carbon black carbonaceous diluent having a surface area less than about 100 m<2>/gram mixed with graphite and a charge transfer active material to provide an electrode active admixture, is described. The carbonaceous diluent/graphite blend increases the charge transfer capability within the electrode while exhibiting diminished cell swelling in comparison to high surface area carbonaceous diluents. A preferred carbonaceous diluent is SHAWINIGAN BLACK TM carbon. |
