Cathode active material for alkaline storage battery and cathode using the same |
摘要 |
The present invention discloses a cathode active material for an alkaline storage battery, which has a high energy density and a high cycle stability. The cathode active material includes particles of a solid solution or eutectic mixture nickel oxide, which has a crystal structure of beta -Ni(OH)2 and contains at least Mn, where Mn has a mean valence of not less than 3.3, and a coating layer of a solid solution or eutectic mixture cobalt oxide formed on the surface of the particles, which contains at least one element of Ni and Mn. <IMAGE> |
