Solid-State Battery Materials for Long-Cycle Energy Storage
Solid-state battery materials are emerging as a transformative solution for long-cycle energy storage due to their enhanced safety, higher energy density, and extended lifespan compared to conventional liquid-electrolyte batteries. By replacing flammable liquid electrolytes with solid electrolytes—such as ceramic oxides, sulfides, and solid polymers—these batteries significantly reduce risks related to leakage, thermal runaway, and combustion. Solid electrolytes also enable the use of high-capacity electrode materials, including lithium metal anodes, which can greatly improve energy density and cycling stability. A key research focus in solid-state batteries is the development of materials with high ionic conductivity at room temperature while maintaining mechanical stability and chemical compatibility with electrodes. Interface engineering between solid electrolytes and electrodes plays a crucial role in minimizing interfacial resistance and preventing dendrite formation, which ...
