POSITIVE PLATE ACTIVE MATERIAL FOR ALKALINE STORAGE BATTERY AND POSITIVE ELECTRODE |
摘要 |
A positive plate active material for alkaline storage battery which has a high charging efficiency even at high temperatures and a positive electrode are disclosed. The positive plate active material is composed of particles of aggregates of crystals of nickel hydroxide and the surface layer of each particle contains a solid solution of nickel hydroxide and Mn. The solid solution is crystals grown on the crystals of nickel hydroxide and/or crystals independent of the crystals of nickel hydroxide. The content of Mn in the solid solution is more than 1 mol % of the total amount of metallic ions in the solid solution and less than 10 mol % of the total metallic ions in the nickel oxide active material and the solid solution. The positive electrode for alkaline storage battery contains the active material and at least one element selected from among Ca, Sr, Ba, Cu, Ag, Cd, Y, and Yb. |
