What Are Lifepo4 Batteries And When Should You Choose Them
How Are LiFePO4 Batteries Different? Strictly speaking, LiFePO4 batteries are also lithium-ion batteries. There are several different variations in lithium battery chemistries, and LiFePO4 batteries use lithium iron phosphate as the cathode material (the negative side) and a graphite carbon electrode as the anode (the positive side). LiFePO4 batteries have the lowest energy density of current lithium-ion battery types, so they aren’t desirable for space-constrained devices like smartphones. However, this energy density tradeoff comes with a few neat advantages....
