[Objective]All-solid-state batteries,known for their high energy density and enhanced safety,are considered a highly promising next-generation energy storage technology.This paper aims to systematically review the progress in key materials and technologies for all-solid-state energy storage batteries,analyze their current challenges and future development directions,and provide references for related research,development,and optimization.[Methods]Through literature review,this paper first elaborates on the fundamental principles and research challenges of all-solid-state batteries.It systematically evaluates the research status and modification strategies for three key material categories:cathode,electrolyte,and anode,with a focus on the characteristics of oxide,sulfide,and polymer electrolytes,as well as LiCoO2,high-nickel ternary,and LiFePO4 cathodes,along with lithium metal,silicon,and carbon-based anodes.Furthermore,from the perspectives of key technologies such as interface engineering,structure and process optimization,and safety and cycle life enhancement,it discusses interface failure mechanisms and control strategies,fabrication processes such as multilayer stacking,hot pressing,and cold sintering,as well as strategies for lithium dendrite suppression and thermal runaway prevention.[Results]Analysis shows that strategies such as element doping,interface coating,composite structure design,and advanced manufacturing processes can effectively enhance the ionic conductivity of solid electrolytes,improve electrode/electrolyte interface stability,and suppress lithium dendrite growth,thereby improving the overall performance of all-solid-state batteries.The cited research works demonstrate significant progress in material modification and interface optimization.[Conclusion]All-solid-state batteries have broad application prospects in fields such as electric vehicles and high-end consumer electronics.However,their large-scale commercialization still faces challenges such as interface impedance,cost,and manufacturing processes.Future efforts require interdisciplinary collaboration and synergistic innovation in technologies such as materials genomics,artificial intelligence,advanced characterization,and simulation to drive the research,development,and industrialization of high-performance,safe,and low-cost all-solid-state batteries.
