聚合物人工固体电解质界面层的研究进展
Research progress of polymer artificial solid electrolyte interface layer
摘要
Abstract
Lithium metal anode has become a research hotspot in the field of rechargeable batteries due to its extremely high specific capacity(3 860 mAh/g)and low electrochemical potential(-3.04 V).However,the instability of lithium metal can promote the formation of dendrites,and the uncon-trolled interface reaction during charge and discharge can cause the generated solid electrolyte inter-phase(SEI)to be unstable,affecting the battery cycling life.By introducing artificial SEI(ASEI),the mechanical and electrochemical properties are improved.The goal is to prepare lithium metal batter-ies(LMBs)with long cycle life and high energy density.Polymers are highly flexible and capable of designing their structures to meet specific needs,making them ideal materials for artificial SEI.In this paper,the properties and functions of artificial SEI are summarized.According to the types and functions of different functional groups of polymers,the research progress of artificial SEI is summa-rized,and the future research direction and development prospect are prospected.关键词
