phosphate lithium battery for back power
The lithium iron phosphate (LiFePO
4) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO
4 as a cathode material, and a graphitic carbon electrode with a metallic current collector grid as the anode. LiFePO
4 batteries have somewhat lower energy density than the more common lithium cobalt oxide (LiCoO
2) design found in consumer electronics, but offer longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer. LiFePO
4 is finding a number of roles in vehicle use and backup power.
