Description
Summary:A layered oxide Li[Ni 1/3Mn 1/3Co 1/3]O 2 was synthesized by an oxalate co-precipitation method. The morphology, structural and composition of the as-papered samples synthesized at different calcination temperatures were investigated. The results indicate that calcination temperature of the sample at 850°C can improve the integrity of structural significantly. The effect of calcination temperature varying from 750°C to 950°C on the electrochemical performance of Li[Ni 1/3Mn 1/3Co 1/3]O 2, cathode material of lithium-ion batteries, has been investigated. The results show that Li[Ni 1/3Mn 1/3Co 1/3]O 2 calcined at 850°C possesses a higher capacity retention and better rate capability than other samples. The reversible capacity is up to 178.6 mA·h·g −1, and the discharge capacity still remains 176.3 mA·h·g −1 after 30 cycles. Moreover, our strategy provides a simple and highly versatile route in fabricating cathode materials for lithium-ion batteries.
