NICKEL HYDROXIDE ACTIVE MATERIAL FOR ALKALINE STORAGE BATTERY AND POSITIVE PLATE |
摘要 |
A nickel hydroxide active material for alkaline storage battery which has a high charging efficiency at high temperatures and a high capacity density and a nickel plate electrode using the active material are disclosed. The nickel hydroxide active material contains 10-40 mol % of Mn with respect to the total amount of metallic ions and is made substantially of beta -type nickel hydroxide. The X-ray diffraction pattern of this active material observed using K alpha rays of Cu has a peak PA having a peak top in the range of 5 DEG -14 DEG of angle of diffraction 2θand a peak PB having a peak top in the range of 18 DEG -20.5 DEG . The relative integrated intensity ratio between the peaks is less than 1/2. The nickel positive electrode contains the above-mentioned active material and a compound, such as Y2 O3 to raise the oxygen producing potential. <IMAGE> |
