Performance and electrochemical characterization studies of advanced high-power bipolar nickel/metal hydride batteries

This paper addresses recent activities relating to energy storage systems capable of delivering very high power. Specific power in the range of 2.0–2.2 kW/kg and power density in the range of 5.0–6.5 kW/l were obtained at current densities of 0.43–0.86 A/cm2 (400–800 A/ft2). The designs incorporate the use of thin, plastic bound electrodes laminated to nickel foil substrates. The units tested were nominal 28 V, 24 Ah batteries, as well as individual cells.
