Lithium Iron Phosphate Battery Comparison

"Lithium Iron Phosphate (LiFePO4) is generally considered to be the most promising new battery chemistry for use in electric vehicles. Although energy density is somewhat lower than Lithium Cobalt type cells (like those used in laptops and mobile phones), LiFePO4s are far more robust and offer much longer cycle life, in the order of 2000-3000 cycles. This makes them a much safer and more economically viable option."
