Nickel electrode for alkaline secondary battery and alkaline secondary battery |
摘要 |
A nickel electrode for an alkaline secondary battery includes an electrically conductive base plate, and an active material particle supported on the conductive base plate and including a complex particle with a surface layer that mainly formed of a high-order cobalt compound whose oxidation number of cobalt is higher than +2 on a surface of a core layer particle that forms a high-order nickel hydroxide whose oxidation number of nickel is higher than +2. Lithium (Li) is contained to be a solid solution in the active material particle from 0.01 to 0.5 wt % of a converted amount as a lithium metal by weight of lithium metal divided by a total weight of the high-order nickel hydroxide, the high-order cobalt compound and the lithium metal. |
