What''s the chemical equation for the lithium iron phosphate battery
The title says it all, I''m searching for the chemical equation to the lithium iron phosphate battery. I know that the cathode is made of $ce{LiFePO4}$ and that upon discharging, it is transformed to $ce{FePO4}$. The Anode is made of graphite. So I think that the reaction on the anode is: $ce{LiFePO4 -> FePO4 + Li+ + e-}$ Is this correct?
Batteries use a chemical reaction to do work on charge and produce a voltage between their output terminals. The basic element is called an electrochemical cell and makes use …
