Nickel hydrogen battery development: Final report

Technical Report ·
OSTI ID:6709847

Development continued on a sealed nickel hydrogen battery for deep discharge, 20-year life, terrestrial energy storage applications that would be cost-competitive with a lead-acid battery. A 7 kWh battery was fabricated, tested, and delivered to Sandia. It consists of four battery modules, each with ten 150 Ah cells in series. These modules are assembled into pressure vessels. The modules are connected in a serials/parallel arrangement resulting in a nominal 300 Ah at 24 volts. During testing at JCI, the battery delivered 7.85 kWh with an energy efficiency of 84%. 10 refs., 22 figs., 26 tabs.
