Alkaline cell |
摘要 |
The active cathode material of an alkaline cell is a mixture of monovalent silver oxide and graphite or a compound of which the main ingredient is divalent silver oxide. The active anode material is powdered mercury-indium-zinc alloy mixed with a suitable binder and pressed into formed or gelled state. After almost all of the zinc of the anode material is exhausted during the course of discharge of the cell, a small quantity of indium acts as the anode active material so as to continue to supply current for a period of time but at lower voltage. By detecting the voltage drop, it can be determined that the cell is approaching the end of its useful life.
