摘要:
An active composition for the electrode of an alkaline electrochemical cell. The active composition comprises an active electrode material and an additive material selected from the group consisting of a Raney alloy, and a Raney catalyst. The active composition may be used to form metal hydride electrodes.
摘要:
A layered hydrogen absorbing alloy electrode for an alkaline electrochemical cell. The layered electrode comprises a outer layer comprising a metal oxide, metal sulfide or mixtures thereof. The outer layer reduces the internal pressure of electrochemical cell.
摘要:
An alkaline electrochemical cell having a hydrogen absorbing alloy negative electrode. The electrochemical cell comprises an alkaline electrolyte comprising an additive material which reduces cell pressure by decreasing hydrogen gas evolution.
