| 英文摘要: |
| Traditional carbonate electrolyte can be easily oxidized and decomposed continuously under high pressure condition, which seriously restricts the development of high voltage lithium battery. Therefore,it is necessary for designers to design and synthesize new high-pressure electrolytes, in order to be up to the concept of sustainable development and green chemistry to a certain extent. The dominating reasons why carbonate-based electrolyte under high pressure condition can be oxidized and the status of the traditional electrolytes are described in this paper. In addition to that, the recent advances of new several high-pressure electrolytes such as carbonates,nitriles, sulfones and ionic liquids are reviewed. The effect and mechanism of the electrolyte under high pressure are discussed in detail, which provided the direction for enhancing the stability of electrolyte, reducing the viscosity, improving the conductivity as ell as safety performance,based on these ways,which accurately lay the foundation for the further industrialization of high-pressure electrolyte. |
