| 中文摘要: |
| 电解质作为锂电池的主要部件之一，充放电过程中对锂离子传输起着重要的作用。然而传统液态电解质漏液以及充放电过程中锂枝晶生长等问题造成了安全事故频发。相比于液态电解质，凝胶聚合物电解质（GPE）将隔膜与电解质一体化，从整体上提高了安全性能和电化学性能。纤维素因其优异的热稳定性、良好的机械性能以及强电解质亲和力等优势，近年来在GPE研究领域得到了广泛关注。本文综述了微米纤维素、纳米纤维素、再生纤维素以及纤维素衍生物目前在GPE领域的研究进展，分析了不同纤维素基质或功能填料对复合GPE的性能影响，最后提出纤维素基GPE用于高性能锂电池所面临的挑战并对其研究前景进行展望。 |
| 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. |
