Metastable Materials for All-Solid-State Batteries

抄録

Materials with metastable structures often exhibit high stability up to a certain temperature, despite not being thermodynamically stable. Therefore, it is important to use the excellent physical properties generated by metastable structure. Secondary batteries are an energy device that stores chemical energy by producing thermodynamically metastable materials. Metastable materials can also be directly utilized as the electrode active materials and the solid electrolytes. The rapid quenching and mechanochemical processes are useful to obtain room temperature metastable materials. This review provides an overview of our research progress on glassy and metastable crystalline materials for all-solid-state batteries.
