【摘要】 作为锂离子电池新型正极材料的正交晶系橄榄石型LiFePO4兼具其他正极材料的优点, 特别是其价格低廉,无毒,热稳定性好,对环境无污染等更使它成为最有潜力的正极材料之一。通过XRD、SEM、TEM对其形貌及结构进行分析,并进行充放电循环测试,研究掺杂对其电化学性能的影响。关键字:锂离子电池正极材料磷酸亚铁锂改性更多还原

【Abstract】 Olivine LiFePO4 is emerging as one of the most promising cathode material for Li-ion batteries. It has predominant advantages such as inexpensive, non-toxic, environmental benign, and is a potential active material to replace LiCoCO2. The samples synthesized by different conditions, and researched electrochemical properties by XRD, SEM, TEM and charge/discharge cycle.更多还原
