Research Progresses of Micro/Nano-Structured LiFePO4 Cathode Material for Lithium-ion Batteries

Nanostructured LiFePO4 cathode materials is an effective method to improve its kinetic performance due to the advantages of small particle size and large specific surface area. However, the practical application of nano-LiFePO4 material also has litany problems because of its poor processing performance. Preparation of nano/micro assembled LiFePO4 material with nano primary particles and micro secondary particle could improve the processing performance of nano-LiFePO4 material. In this paper, we reviewed the research progresses of micro/nano-structured LiFePO4 material recently, mainly on the progresses of micro/nano-structured LiFePO4 material with regular morphology.
