The demand for high performance and long life storage systems has lead to numerous research initiatives, aimed at the development of such systems. Developmental paths are aligned with the requirements of the applications of these systems. A detailed understanding of technical characteristics and cost considerations is provided in this paper for various battery chemistries: contemporary, vintage, and prospective. A clear understanding of battery characteristics is essential for guiding the selection of such batteries. Indeed, because of the critical functions fulfilled by batteries as well as the substantial costs of advanced batteries, a realistic appraisal of candidate battery performance and costs against requirements is key to judging the prospects of new applications such as EV, HEV, and plug-in hybrid electric vehicles (PHEV). Although electric vehicles (EVs) have been around since before 1900 the limitations of the batteries to drive them have not enabled them to compete in the general consumer’s market with the internal combustion engine. Automotive parts are limited by space and weight. Therefore EVs and hybrid electric vehicles (HEVs) require a battery with high energy density. Specific energy is defined as the energy per kilogram of the battery while energy density is the energy per unit volume. Early designs (1990–1995) of lithium-ion batteries only had a specific energy of 0.2 kWh/kg. EVs also require a battery with high power output for large power draw, such as quick acceleration. The General Motors EV1 had a battery pack weighing almost 600 kg while the car weighed 1,350 kg. The battery would then account for more than 44% of the car’s weight. A marked improvement in energy cell density of batteries was required for practical EVs.
