英文摘要	由溶胶凝胶法合成的锂离子电池正极材料LiNi1/3Co1/3Mn1/3O2在水溶液体系中具有优异的高倍率充放电性能,放电时能够输出极高功率密度.XRD表征证明合成的LiNi1/3Co1/3Mn1/3O2材料具有层状α-NaFeO2结构,SEM形貌显示材料的粒径约为500nm,恒电流充放电测试表明LiNi1/3Co1/3Mn1/3O2材料在pH12的2mol·L-1LiNO3溶液中,以2C(0.36A/g)倍率充放时,比容量达到了147mAh/g.如以80C(14.4A/g)、150C(27A/g)和220C(39.6A/g)的倍率充放,材料的比容量仍可达到64mAh/g、33mAh/g和16mAh/g,而全电池的功率密度分别达到2574W/kg、3925W/kg、4967W/kg.其中80C倍率充放,经1000周循环后,容量保持率为90.9%.; The cathode material of LiNi1/3Co1/3Mn1/3O2 synthesized by sol-gel method shows excellent high rate performance,and high output power density during discharge process. A well-ordered layered α-NaFeO2 structure was confirmed by XRD and a primary particle size of about 500 nm was indicated by SEM. Galvanostatic charge-discharge test indicates that LiNi1/3Co1/3Mn1/3O2 in 2 mol·L-1 LiNO3 aqueous solution with pH 12 reached a ca-pacity of 147 mAh/g while charged and discharged at 2C. The capacities were 64、33、16 mAh/g with 80C ( 14. 4 A/g) 、150C( 27 A/g) and 220C ( 39. 6 A/g) charge/discharge rates,while the power densities of the battery were 2574 W/kg、3925 W/kg、4967 W/kg,respectively. It retained 90. 9% of the initial capacity after 1000 cycles at 80 C.; 作者联系地址：厦门大学固体表面物理化学国家重点实验室,化学化工学院化学系;; Author's Address: State Key Lab of Physical Chemistry of Solid Surfaces,Department of Chemistry, College of Chemistry and Chemical Engineering,Xiamen University,Xiamen 361005,Fujian,China
