Special Issue Information

Dear Colleagues,

Rechargeable batteries are becoming increasingly attractive for promoting a fossil fuel-free world. Current commercialized Li-ion batteries have a variety of cathodes and anodes, but they almost exclusively employ liquid electrolyte (LE). These highly flammable organic electrolytes are the primary safety concern. The most commonly cited battery systems that promise to deliver improved safety and increased energy density are those with a pure Li metal anode and a solid electrolyte (SE) to form a solid-state battery (SSB). Despite their potential, SSBs face critical challenges. Lithium dendrite growth through the SE can lead to battery failure due to electrical shorting, and unstable interactions at the cathode/SE interface can cause rapid capacity decay. These issues significantly hamper the further development and commercialization of SSB technology.

Therefore, the focus of the present Special Issue, entitled “Advances in Solid Electrolytes and Solid-State Batteries,” is twofold. First, it seeks to explore the design of high-performance SSBs, leveraging the latest advances in materials science and engineering. Second, it aims to deepen the understanding of the electrolyte/electrode interface properties and the mechanisms underlying SSB failure. By addressing these critical areas, this Special Issue contributes to the ongoing efforts to overcome the current limitations and unlock the full potential of SSB technology for a more sustainable and safer energy future.

Solid-state lithium batteries (SSLBs) have emerged as a promising alternative to conventional lithium-ion systems due to their superior safety profile, higher energy density, and potential compatibility with lithium metal anodes. However, a major challenge hindering their widespread deployment is the formation and growth of lithium dendrites, which compromise both performance and safety. This review provides a comprehensive and structured overview of recent advances in dendrite suppression strategies, with special emphasis on the role played by the nature of the solid electrolyte. In particular, we examine suppression mechanisms and material innovations within the three main classes of solid electrolytes: sulfide-based, oxide-based, and polymer-based systems. Each electrolyte class presents distinct advantages and challenges in relation to dendrite behavior. Sulfide electrolytes, known for their high ionic conductivity and good interfacial wettability, suffer from poor mechanical strength and chemical instability. Oxide electrolytes exhibit excellent electrochemical stability and mechanical rigidity but often face high interfacial resistance. Polymer electrolytes, while mechanically flexible and easy to process, generally have lower ionic conductivity and limited thermal stability. This review discusses how these intrinsic properties influence dendrite nucleation and propagation, including the role of interfacial stress, grain boundaries, void formation, and electrochemical heterogeneity. To mitigate dendrite formation, we explore a variety of strategies including interfacial engineering (e.g., the use of artificial interlayers, surface coatings, and chemical additives), mechanical reinforcement (e.g., incorporation of nanostructured or gradient architectures, pressure modulation, and self-healing materials), and modifications of the solid electrolyte and electrode structure. Additionally, we highlight the critical role of advanced characterization techniques—such as in situ electron microscopy, synchrotron-based X-ray diffraction, vibrational spectroscopy, and nuclear magnetic resonance (NMR)—for elucidating dendrite formation mechanisms and evaluating the effectiveness of suppression strategies in real time. By integrating recent experimental and theoretical insights across multiple disciplines, this review identifies key limitations in current approaches and outlines emerging research directions. These include the design of multifunctional interphases, hybrid electrolytes, and real-time diagnostic tools aimed at enabling the development of reliable, scalable, and dendrite-free SSLBs suitable for practical applications in next-generation energy storage.
