Abstract :
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 LiFePO4 (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-1. The reversibility of Li extraction is 81 % mol. The battery shows discharging capacity of ~ 128 mAh.g-1 at first cycle. It indicates that the performance may decrease fast due to less reversibility of Li extraction.
