Solid-state electrolytes serve as the core materials in solid-state lithium batteries and are typically composed of polymers, ceramics, or composite materials. These materials exhibit high ionic conductivity and superior mechanical stability, enabling the efficient transport of lithium ions while simultaneously ensuring the structural stability and safety of the battery. Common solid-state electrolyte materials include:
Polymer Electrolytes: Such as poly(ethylene oxide) (PEO)-based and poly(methyl methacrylate) (PMMA)-based electrolytes.
Ceramic Electrolytes: Such as oxides and sulfides.
Composite Materials: Materials that combine the advantages of both polymers and ceramics to enhance overall performance.
