Special Issue Information

Dear Colleagues,

Solid-state batteries (SSBs) represent a transformative advancement in energy storage, offering enhanced safety, higher energy density, and longer cycle life compared to conventional lithium-ion batteries (LIBs). This Special Issue focuses on the latest research developments in electrolytes and electrode materials, which are critical to unlocking the full potential of SSBs. It highlights innovations in solid electrolytes (SEs)—including sulfide, oxide, and polymer-based systems—with emphasis on ionic conductivity, interfacial stability, and mechanical properties. Additionally, the issue explores breakthroughs in electrode design, such as composite architectures and novel active materials, which address challenges in compatibility and performance. By bringing together cutting-edge experimental and theoretical studies, this collection aims to provide a comprehensive overview of the current state of progress and future directions in the field. We invite the submission of original research and review articles on a wide range of topics, including the synthesis and characterization of solid electrolytes, interface engineering, advanced electrode materials, modeling and simulation, and practical applications of solid-state battery systems. The insights presented here are expected to accelerate the development of next-generation solid-state battery technologies for applications ranging from portable electronics to electric vehicles and grid storage.

Graphene, owing to its exceptional mechanical properties and interfacial modulation capability, is considered an ideal material for enhancing the interfacial strength and damage resistance during the fabrication of ultra-thin lithium foils. Although previous studies have demonstrated the reinforcing effects of graphene on lithium metal interfaces, most analyses have been restricted to single-temperature or idealized substrate conditions, lacking systematic investigations under practical, multi-temperature environments. Consequently, the influence of graphene coatings on lithium-ion conductivity and mechanical stability under real thermal conditions remains unclear. To address this gap, we employ LAMMPS-based molecular dynamics simulations to construct atomic-scale models of pristine lithium and graphene-coated lithium (C/Li) interfaces at three representative temperatures. Through comprehensive analyses of dislocation evolution, root-mean-square displacement, frictional response, and lithium-ion diffusion, we find that graphene coatings synergistically alleviate interfacial stress, suppress crack initiation, reduce friction, and enhance ionic conductivity, with these effects being particularly pronounced at elevated temperatures. These findings reveal the coupled mechanical and electrochemical regulation imparted by graphene, providing a theoretical basis for optimizing the structure of next-generation high-performance lithium metal anodes and laying the foundation for advanced interfacial engineering in battery technologies.
