Lithium-ion and lithium polymer batteries were initially developed for use in cell phones, laptops and other electronics. With their high energy density and long cycle life they have become the standard battery type for use in EVs.
More recent EVs use new lithium-ion battery chemistry that provides fire resistance, environmental friendliness, rapid charging (as quickly as a few minutes), and a longer battery lifespan. These chemicals (phosphates, titanates, spinels, etc.) have been proven to have a significantly longer lifetime, with A123 types using lithium iron phosphate lasting more than 10 years and more than 7000 charge/discharge cycles. LG Chem expects their new lithium-manganese spinel batteries to last up to 40 years.
