RECHARGEABLE ALKALINE MANGANESE CELL HAVING REDUCED CAPACITY FADE AND IMPROVED CYCLE LIFE |
摘要 |
Rechargeable galvanic cells are disclosed which comprise a manganese dioxide cathode, a zinc anode and a potassium hydroxide electrolyte wherein the cathode includes additive compounds to increase the cycle life and cumulative discharge capacity of the cell. The additives comprise at least a strontium compound and optionally a barium and/or calcium compound. Cells including the additive(s) desirably have an individual discharge capacity after 50 deep discharge-charge cycles of at least 0.100 Ah/gMnO2. |
