钠离子电池负极人工固体电解质界面设计研究进展
Research progress on artificial solid electrolyte interphase design for sodium-ion battery anodes
摘要
Abstract
Sodium-ion batteries(SIBs)are a potential alternative to lithium-ion batteries(LIBs)due to their low cost and abundant resources.However,the unstable solid electrolyte interphase(SEI)formed at the anode interface causes reversible capacity fading and low Coulombic efficiency,which severely limits their practical application.Constructing an artificial SEI is a key strategy to enhance anode performance,as it can facilitate the uniform deposition/stripping of Na+,mitigate volume changes during cycling,and effectively suppress dendrite growth.This review focuses on the research progress of artificial SEI in improving the performance of SIB anodes.Firstly,it analyzes the inherent defects of natural SEI and the design mechanisms of artificial SEI.Subsequently,targeting common anode materials such as metallic sodium and hard carbon,it systematically reviews the research status of inorganic,organic,and composite artificial SEI:inorganic layers exhibit high mechanical strength and corrosion resistance,but high brittleness;organic layers feature tunable structures and excellent toughness,but insufficient stability;composite layers,by integrating the advantages of both,can provide more ideal solutions.Finally,this paper proposes that future research should focus on optimizing the preparation process of artificial SEI films,and deeply integrate theoretical calculations with in-situ microstructure characterization techniques to investigate the structure regulation mechanisms,ion transport behaviors of these artificial SEI films,and their compatibility with electrolytes so as to provide theoretical support and technical route references for overcoming the bottlenecks in terms of industrialization costs and applications under harsh operating conditions.关键词
