Battery powered electric vehicles (EVs) and hybrid electric vehicles (HEVs) have been gaining market share as the public’s environmental concerns and the depletion of fossil fuels drive the demand for better fuel efficiency. But great improvements in the mileage one can drive before recharging, a faster recharging method, and the creation of a recharging infrastructure akin to today’s gas stations are needed before fully electric vehicles will be practical for day-to-day use.

An increase in battery efficiency is one of the biggest challenges engineers face. While Li-ion batteries are currently the best option available, they are by no means the ultimate in battery technology: there is much room for improvement. The high mass of Li-ion batteries reduces fuel efficiency in automobiles, and their potential flammability makes them dangerous, particularly in the event of a crash. Researchers worldwide are trying to develop a better battery to replace Li-ion technology. For now, optimizing the configuration of Li-ion batteries is the best method for increasing battery performance.
