This paper reviews and analyzes the current and future battery technologies suitable for transportation applications. The success of battery-enabled hybridization of gasoline and diesel power-trains in the past decade has clearly established it as the most credible alternative to the conventional propulsion systems. The current enthusiasm for electric vehicles further accentuates this success. In this paper, we compare the performance of a number of established and emerging battery technologies against the now well-established performance targets for electric-drive vehicles. Lithium-ion cells' superior performance and life are described, as are requirements for supplantation of NiMH cells in vehicles. Trends are discussed in technology development, which has largely been achieved through insertion of Li technologies in consumer electronics. Recent developments have given rise to several variants of the Li ion chemistry.
