Comprehension-driven design of advanced multi-block single-ion conducting polymer electrolytes for high-performance lithium-metal batteries

The continuously growing importance of batteries for powering(hybrid) electric vehicles and storing renewable energy has prompted a renewed focus on lithium-metal batteries (LMBs) in recent years,as its high theoretical specific capacity of about3860 mA h g-1and very low redox potential (-3.04 V vs.the standard hydrogen electrode) promise substantially higher energy densities compared to current lithium-ion batteries (LIBs)[1].However,lithium metal electrodes face severe challenges associated with the risk of dendritic lithium deposition and the high reactivity with traditional organic liquid electrolytes,resulting in a continuous loss of electrochemically active lithium and a relatively low Coulombic efficiency[2].To address these challenges,solid inorganic and polymer electrolytes have emerged as a potentially safer alternative.
