One-step mechanical synthesis of LiFePO4/C composite granule under ambient atmosphere

A new approach to prepare LiFePO4/C composite granule as cathode for lithium-ion batteries has been demonstrated. The LiFePO4/C composite granule was synthesized by one-step mechanical process under ambient atmosphere without external heating. The obtained granule consisted of nano-sized primary particles. The new synthetic method which is achieved by using an attrition-type mill does not require an inert gas to prevent iron oxidation. The initial electrochemical performance of the LiFePO4/C composite granule was also investigated.
