Abstract

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.
