高比能固态锂硫电池研究进展
Research progress on high specific-energy solid-state lithium-sulfur batteries
摘要
Abstract
Solid-state lithium-sulfur batteries(SLSBs)are among the most promising next-generation energy storage devices due to their high theoretical energy density and low cost.Compared to conventional lithium-sulfur batteries(LSBs)with liquid electrolytes,SLSBs have the potential to eliminate the shuttle effect,thereby extending battery lifespan.However,substantial challenges remain,particularly regarding fundamental mechanisms and manufacturing processes.These include understanding the solid-solid conversion mechanism from S8 to Li2S to identify limiting factors and potential solutions,constructing a dynamic and stable charge transfer network for high-loading cathodes,and managing dendrite growth and strain regulation in the lithium metal anode.Addressing these challenges requires innovative electrode material design,interface optimizations,and advanced characterization techniques using in-situ and ex-situ methods.This review highlights recent research advancements in SLSBs,focusing on cathodes,anodes,and characterization methods.Additionally,we summarize key differences between SLSBs and LSBs in terms of cathode material and electrode structures.For the cathode,it is essential to maintain efficient charge percolating pathways for both ions and electrons while regulating electrode deformation.Increasing the critical current density of lithium stripping for the anode is crucial for achieving high specific-energy in SLSBs.Further mechanistic investigations are necessary to design low-strain cell configurations that enable the development of high specific-energy SLSBs.关键词
