摘要: 磷酸铁锂已经成为一种重要的锂离子动力电池正极材料,磷酸铁锂的合成方法分为固相法和液相法.液相法合成对材料的微观形貌影响较大,在合成具有特定形貌和尺寸的磷酸铁锂材料时,仍然以液相法合成为主.本文较详细地介绍了近年来液相法中的溶剂热法和溶胶-凝胶法制备磷酸铁锂的研究进展,包括传统的水热合成和非水溶剂热合成以及溶胶-凝胶法在某些具有特殊微结构的磷酸铁锂制备中的研究进展.

Abstract: After more than a decade LiFePO4 has become a widely used cathode material for lithium ion batteries due to its intrinsic properties such as safety and stability. Its preparation method includes solid state reactions and liquid phase reactions, of which liquid phase route has advantages of unique morphology and sizes. This work summarizes our recent work on the conventional hydrothermal and anhydrous-solvothermal processes and sol-gel methods for preparing LiFePO4 with special microstructures.

Key words: lithium ion batteries, LiFePO4, solvothermal synthesis, hydrothermal synthesis, sol-gel method
