Study on the LiFePO₄ Doped with MWCNTs by Ball Milling

Abstract:

The fine cathode material of LiFePO₄/MWCNTs composite was synthesized by ball milling. XRD demonstrated that the particle size of material was smaller when it was milled more time. And SEM showed that the MWCNTs was decentralized into the grains of LiFePO₄. The electrochemical performance of the composite electrodes milled 12h exhibited best electrochemical performance. The electroconductibility of this composite was larger than the others. The specific capacity of it was 132.8mAh/g. So appropriate milling can promote the performance of LiFePO₄/MWCNTs composite.
