Abstract
The present invention provides a positive electrode for a rechargeable cell including a two-dimensional electrically conductive substrate supporting a coating comprising nickel hydroxide and a binder, preferably a styrene-ethylene/butylene-styrene triblock copolymer binder. The coating is formed by applying a paste to the two-dimensional substrate surface. The present invention also includes the cell made therefrom. The present invention further provides a method of producing this electrode including the steps of forming the paste and coating the paste onto the two-dimensional substrate. The capacity, midpoint voltage and power delivery of the coated electrode are comparable to or exceed those of traditional sintered and foam positive electrodes.
