Research progress of 1,3,5-trioxane-based high-performance electrolytes for lithium batteries
The development of rechargeable lithium batteries for high energy density,high safety and long service life is continuously driven by the growing demand for electric vehicles.As a crucial component of lithium batteries,electrolytes play an extremely important role in the safety property,energy density and even service life of lithium batteries.Hence,electrolytes of high performance are highly desirable.1,3,5-trioxane(TXE)is one of the most accessible and cheapest materials for the synthesis of polyformaldehyde(POM).Besides,it is one of the most promising candidates for preparing high-performance electrolytes because it could not only improve the interface compatibility with electrodes but also enhance the safety performance of the lithium battery.Significant efforts have been devoted to developing the TXE-based electrolyte to build high-energy density and high-safety performance lithium batteries.Therefore,this review mainly summarizes the classification and development of TXE-based high-performance electrolytes for both quasi-solid-state and liquid-state lithium batteries.In addition,the detailed construction and characterization of the as-formed electrode/electrolyte interface are also illustrated.Moreover,the application of TXE-based electrolytes as quasi-solid electrolyte precursors,copolymer electrolytes,thermally induced automatic shutdown electrolytes and co-solvent in liquid electrolytes,respectively,are also presented and discussed in detail.In the end,the remaining challenges and future development trends of TXE-based high-performance electrolytes are prospected.
