Enhanced properties of LiFePO4/C cathode materials modified by CePO4 nanoparticles

• The composites were coated by carbon layer and modified by CePO4 nanoparticles.
• Introducing CePO4 nanoparticles via in situ method had obvious nail effects in reducing the particle size of LiFePO4.
• The electrochemical properties were improved significantly after modification of CePO4 nanoparticles.

Reducing the particle size and coating conductive materials are both effective ways to improve the performance of LFP (LiFePO4). In this paper, we synthesized LFP/C/CPO (LiFePO4/C/CePO4) composites and investigated the effects of CePO4 modification on the morphologies and electrochemical properties of LFP/C composites. The results demonstrated that introducing CePO4 nanoparticles via in situ method could reduce the particle size significantly and improve the electrochemical properties of LFP/C.
