The performance of LiFePO4 battery with graphite waste as anode material

A research on the preparation of graphite waste powder from zinc-carbon primary battery has been conducted in order to use the powder as anode material for LiFePO
₄
(LFP) battery. The result shows that the component of graphite powder is dominated with carbon and some impurities. The LFP battery with graphite waste powder shows charging capacity of ~158 mAh.g

. The reversibility of Li extraction is 81 % mol. The battery shows discharging capacity of ~ 128 mAh.g

at first cycle. It indicates that the performance may decrease fast due to less reversibility of Li extraction.
