摘　　要：纳米LiFePO4正极材料由于具有颗粒小、比表面积大的优势,是改善其动力学性能的有效手段,但由于较差的加工性能使其发展受限。通过纳微组装制备一次粒子为纳米颗粒,二次粒子为微米颗粒的微纳米LiFePO4正极材料可以改善纳米材料的加工性能。本文综述了近期微纳米LiFePO4正极材料的研究方向,主要介绍了规则形貌的微纳米LiFePO4正极材料的研究进展。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 many 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.
