Cathode material Li[Ni1/3Co1/3Mn1/3]O2 for lithium-ion batteries with layered hexagonal structure was successfully synthesized in sol-gel way. The influences of calcination temperature (from 700° to 1000°C) on the structure and electrochemical behaviors of Li[Ni1/3Co1/3Mn1/3]O2 were extensively investigated. The results of XRD show that all samples are isostructural with α-NaFeO2 with a space group R-3m. XPS analysis shows that the oxidation states of Co and Mn were Co3+ and Mn4+ respectively, while Ni exists as Ni2+ and Ni3+. The charge-discharge experiments show that the sample calcined at 850°C delivers 194.8mAh/g in the first cycle at C/5 rate in 2.5-4.3V potential range.

Gradual Loss

The cathode materials of LiFePO4 batteries decreases due to the gradual loss of lithium content during use. In this paper, the spent cathode materials were recycled with a carbon layer coated. The samples were prepared by a high temperature impurity removal procession and a solid phase repairing method. The LiFePO4 material obtained by the regeneration process has a discharge specific capacity of 105.4 mAh/g at 0.1 C after 10 cycles, and keeps it a considerable retention of 73.1 mAh/g at 1 C. This work provides a new routine in reusing lithium ion batteries.
