固态锂金属电池正极/电解质界面研究进展OA北大核心CSTPCD

Solid-state lithium metal battery has become the most promising lithium battery technol-ogy for its outstanding safety and high theoretical specific capacity. For building a system with high specific energy density,the main obstacle is the interfacial issues and the compatibility between cath-ode and solid electrolyte. Through the introduction of modification strategies on film mechanical property,cathode/electrolyte interface properties and its integrated preparation technology,and theo-retical calculation,etc,the progress of cathode/electrolyte interfacial modification techniques such as physical contact optimization,cathode/electrolyte permeability enhancement,interface compatibility improvement and cathode electrolyte interphase construction were reviewed. The development trend of interface modification technology for solid-state lithium metal batteries was also prospected.
