| 英文摘要: |
| Lithium-rich manganese based cathode material has become one of the most promising cathode materials for lithium-ion batteries due to its characteristics of high energy density, low cost and environmental friendly. However, the serious voltage attenuation of Li-rich manganese based materials has become the major difficulty for their commercialization. Based on the crystal structure of Li-rich materials, the mechanism and influencing factors causing voltage attenuation of materials are summarized, and effective modification strategies are proposed for voltage attenuation. Finally, the future development and research direction of Li-rich cathode material are prospected. |
