Carbon coated lithium cobalt phosphate for Li-ion batteries: Comparison of three coating techniques

► Three techniques are adopted to coat carbon on LiCoPO4 materials. ► The LiCoPO4/C processed via deposition shows a homogeneous carbon coating. ► LCP-deposition delivers a high capacity of 130 mA h g−1 with favorable cyclability. ► A uniform carbon layer is the key to a high and stable electrochemical performance.
