Abstract

Nickel-metal hydride and lithium-ion batteries are the two contenders for hybrid electric vehicle HEV applications. Early entrants such as the Honda Insight and the Toyota Prius use nickel-metal hydride batteries. Lithium-ion batteries with either modified LiNiO2 or LiMn2O4 spinel cathodes are being considered for the next generation HEV. The main advantage of metal hydride batteries is that there is a built in electrochemical mechanism for balancing cells in series and accommodating overcharge. Other advantages are safety and ease of scale-up to large sizes. The major drawback is limited cycle life due to pulverization and corrosion of the metal hydride electrodes. Lithium-ion batteries with the required power for HEV can be designed and built. However, the batteries loose power capability, particularly when cycled or stored at elevated temperatures. This appears to be mostly due to the buildup of electrolyte decomposition products on the surface of the cathodes.
