Research Progress in Organic Polymer Electrolytes for Sodium Ion Batteries
With the advantages of high flexibility,easy processing,easy large-scale production,and controllable electrode interface,organic polymer electrolytes have great potential in promoting the development of high energy density and high safety solid-state batteries.Starting from the two main organic polymer electrolytes,gel polymer electrolyte and solvent-free solid polymer electrolyte,the development and mechanisms of the two electrolytes were reviewed,their physical and chemical properties and their application in sodium-ion batteries were described,and the challenges faced by the two electrolytes and their future research directions were discussed.Finally,the possible problems in the future development of organic polymer electrolyte were presented,and the future development direction of material design and industrial amplification was prospected.
