Nickel-metal hydride secondary battery comprising a compound silicate |
摘要 |
A nickel-metal hydride secondary battery includes positive electrodes including nickel hydroxide, negative electrodes including a hydrogen-absorbing alloy, separators and an alkaline electrolyte. The positive electrode includes a compound silicate. By employing the above construction, the compound silicate reacts with Mn or Al which dissolves out from the negative electrode to inhibit deterioration of electrochemical characteristics of the battery, and thus the life of the battery can be prolonged.
