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

摘要

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/1 were obtained at current densities of 0.43-0.86 A/cm~2 (400-800 A/ft~2). The designs incorporate the use of thin, plastic bound electrodes laminated to nickel foil substrates. The units tested were nominal 28V. 24 Ah batteries, as well as individual cells.
