近年,锂离子电池的正极材料的研究主要集中在含锂金属氧化物。具有橄榄石结构的磷酸铁锂(LiFePO4)以3.5V的充放电平台,高容量、热稳定性好、低成本、环境友好等优点成为最有应用前景的锂离子电池正极材料,是目前锂离子电池正极材料研究的一个热点。本实验采用固相反应合成的LiFePO4粉末,粉末的粒径大约为4μm。将LiFePO4微细粉末装入
In recent years, lithium-ion battery cathode materials mainly concentrated in lithium-containing metal oxides. Lithium iron phosphate (LiFePO4) with olivine structure is the most promising lithium-ion battery cathode material with 3.5V charge-discharge platform, high capacity, good thermal stability, low cost and environmental friendliness, A study of battery cathode material is a hot topic. In this experiment, LiFePO4 powder synthesized by solid-state reaction was used. The particle size of the powder was about 4μm. Load LiFePO4 fine powder
