To surpass the energy density and safety of conventional lithium-ion batteries, solid-state lithium metal batteries (LMBs) have been receiving attention as a next-generation technology. Solid-state electrolytes (SSEs) can facilitate the safe operation of LMBs by suppressing dendritic Li growth. Plastic crystal-embedded elastomer electrolyte (PCEE), featuring a 3D interconnected, ion-conducting plastic crystal phase protected by an elastomer phase, is an emerging SSE that satisfies these requirements. However, the role and formation principle of the 3D bicontinuous structure of the PCEE remain in the veil. Recently, we investigated the phase-separated structures of various PCEEs by systematically adjusting the volume ratio of the phases to elucidate their structure-properties-electrochemical performance relationship of the PCEEs for LMBs. With the optimal structure of PCEE that exhibits both superior Li-ion transport and mechanical properties, the full cell achieves high performance.
