| Abstract: |
| Electrolyte， as one of the main components of lithium batteries， plays an important role in the transport of lithium ions during the charging and discharging process. However， the frequent safety accidents caused by problems such as traditional liquid electrolyte leakage and lithium dendrite growth during charging and discharging seriously limit the wide applications of lithium batteries. Compared with liquid electrolytes， gel polymer electrolytes （GPE） integrate the separate with the liquid electrolyte， and overall improved safety performance and electrochemical performance. Because of its excellent thermal stability， good mechanical properties and strong electrolyte affinity， cellulose has received extensive attention in the field of GPE research in recent years. In this paper， the current research progress of micro-cellulose， nano-cellulose， regenerated cellulose and cellulose derivatives in the field of GPE is reviewed， and the effects of different cellulose matrices or functional fillers on the properties of GPE composite are analyzed， and finally the challenges of cellulose-based GPE in high-performance lithium batteries are proposed， and their research prospects are prospected. |
