摘要
An advance in Ni-Cd rechargeable battery technology is being achieved by introducing positive active material made of pasted nickel hydroxide spherical particles (SP) into a nickel foam. The performance of this kind of electrode, and particularly its improved volumic capacity, are determined by several technological factors, the contributions of which are difficult to dissociate. A composite electrode was prepared by electrodeposition of nickel from a Ni(OH)2 particle suspension in a Watts' bath. A single layer of particles was partly embedded in the nickel coating grown on a nickel support. It is shown that the contribution of the metallic nickel matrix is negligibly small in both kinetic and spectroscopic responses of the electrode hence allowing the behaviour of the nickel hydroxide particles to be investigated.
