With an emphasis on recent developments in solid electrolytes and anodes, the main objective of this review is to present a thorough overview of the state-of-the-art in solid-state batteries (SSBs). The paper opens with a background on the transition from liquid electrolyte lithium-ion batteries to advanced SSBs, stressing their enhanced safety and energy density. It responds to the growing need for effective, secure energy storage in devices like portable gadgets and electric cars. The analysis of solid electrolytes, which are essential to SSB technology, takes up a significant portion of the text. Solid electrolytes are categorised as polymer-based, oxide-based, and sulphide-based, and their unique characteristics and appropriateness for various applications are discussed. The paper also discusses developments in anode materials for SSBs, examining materials like as silicon, lithium metal, and intermetallic compounds with an emphasis on their durability, capacity, and compatibility with solid electrolytes. It tackles issues like interface stability and lithium dendritic development that arise when integrating these anode materials. The most recent analytical methods, experimental research, and computational models to comprehend and enhance the anode–solid electrolyte interface are discussed in this review. These are essential for addressing interfacial resistance and guaranteeing the long-term stability and effectiveness of SSBs. The study's conclusion highlights the potential of SSBs to transform energy storage technologies and makes recommendations for future research and development paths. For scholars, researchers, and business executives involved in the development of advanced battery technology, this review is an essential resource. It provides a thorough summary of the materials and technologies influencing the future of SSBs, offering insights into present issues and possible fixes in this quickly developing industry.
