Abstract

A comparison study of carbon coating on $LiFePO_4$ was done with two different carbon sources-petroleum pitch and Ketjen black. Raman spectroscopy and transmission electron microscopy (TEM) analysis were applied to the carbon-coated $LiFePO_4$. $LiFePO_4$ which was carbon-coated with petroleum pitch showed more uniform carbon layer and ordered carbon structure. Such uniformity and ordered structure of carbon coating layer resulted in higher initial discharge capacity and better rate capability.
