Safety is a key feature touted by the A123 technology, with a video on their website of a nail drive test, in which a nail is driven through a traditional Li-ion battery and an A123 Li-ion battery, where the traditional battery flames up and bubbles at one end, the A123 battery simply emits a wisp of smoke at the penetration site.
Then, during the battery's initial charge (called formation), the cured paste on the plates was converted into electrochemically active material (the active mass). Faure's process significantly reduced the time and cost to manufacture lead–acid batteries, and gave a substantial increase in capacity compared with Planté's battery. [20]

Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
The Cost of Charging an Electric Car. ... At the time of writing, the national average for a gallon of gasoline was $3.39, and the average fuel tank capacity on a small vehicle was 12 gallons ...
Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology (lithium-ion) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). [12] Compared to older battery types such as lead-acid batteries.
