    en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

    The lithium iron phosphate battery (LiFePO. 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO. 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other ...
