Alkaline rechargeable Ni/Co batteries: Cobalt hydroxides as negative electrode materials

Author affiliations

Abstract

It is demonstrated that β-Co(OH)2 has a high discharge capacity and good high-rate discharge ability as a negative electrode material. A new rechargeable battery system with higher energy density, consisting of α-phase nickel hydroxides as the positive electrode material and β-cobalt hydroxides as the negative electrode material, is proposed on the basis of multi-electron reactions.
