| Abstract: |
| The ternary cathode materials, LiNi0.5Co0.2Mn0.3O2, were synthesized by twice high-temperature solid-phase sintering and characterized by SEM, XRD and Land Testing. The results indicate that the layered crystal structure and its morphology is well distributed. The discharge capacity is 151 mAh/g in 2.75~4.25 V at 0.2 C, and the coulombic efficiency is about 93%. This material is an excellent ternary cathode material with high discharge specific capacity. |
