PASTED POSITIVE ELECTRODE AND PROCESS FOR ITS PRODUCTION

摘要

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 dimentional 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.
