Title: High-cycle-life, high-energy-density nickel-zinc batteries. Report No. 5

Technical Report ·
OSTI ID:5327195

The ERADCOM nickel-zinc program, which is jointly funded by the Departments of Energy, Navy and Army, has resulted in the development of 5 ampere-hour nickel-zinc cells that have maintained 79% to 86% of initial capacity after 650 cycles on the C/3 80% DOD cycling regime. One cell is still delivering 70% of initial capacity after 880 cycles. This achievement is primarily due to the employment of an interrupted current (IC) charging mode on every cycle, the optimum frequency being 5 to 8 Hertz at a rest-to-pulse-ratio of 3/1, with charge control being by means of a GRL pressure switch attached to each cell at a cutoff pressure of 8 psig, and venting means at 10 psig. Design and performance characteristics of the battery are reported. (WHK)
