| abstract |
(57) [Problem] To provide nickel hydroxide for an alkaline secondary battery positive electrode active material capable of improving charging efficiency under a high temperature environment. SOLUTION: A powdery nickel hydroxide for a positive electrode active material of an alkaline secondary battery is prepared by setting a proton diffusion coefficient of particles constituting the powder to D (cm 2 · s −1 ) and an average particle diameter of the particles to a. (Cm), the following formula: D / a ≧ 1 × 10 It is assumed that -6 holds. By optimizing the relationship between the proton diffusion coefficient of nickel hydroxide and its particle size, reducing the gradient of the proton concentration in the particles during charging and suppressing the increase in the positive electrode potential, water as the solvent for the electrolytic solution is reduced. The generation of oxygen generated by the electrolysis can be suppressed, and as a result, the charging efficiency is improved even in high-current charging under a high-temperature environment. |
