Summary: Polymer composite electrolytes have garnered attention for their safety and flexibility, but the compatibility issues at the organic/inorganic interface can lead to agglomeration of ceramic particles and hinder Li+ transport. In this study, a silane coupling agent was introduced to build a bridge model at the interface, resulting in improved dispersion, enhanced Li+ conductivity, and broader electrochemical window. The in-situ built bridge model was also applied to various cathodes, leading to uniform morphology and enhanced Li+ diffusion coefficient. These findings offer a universal strategy to address interphase issues and have implications for other composite systems.

Summary: The integration of bismuthene into PEO electrolyte enhances ionic conductivity by weakening the bond strength of O (-EO) and Li+, and disrupting the crystallization of PEO polymer chain. The in-situ formed LixBi-rich layer stabilizes the Li/PEO interface and modulates the interfacial Li+ cycling process, thus preventing the formation of lithium dendrites. The composite electrolyte enables stable cycling of Li symmetric battery for over 1000 hours, exhibiting outstanding long-life cycling and rate performance.

Summary: In this study, an easy-to-construct polymer/inorganic composite solid-state electrolyte (CSSE) was developed by integrating LLZO ceramics into PEO to inhibit the growth of Li dendrites and widen the electrochemical stability window. The designed PLL-CSSE showed outstanding cycling performance and high Coulombic efficiency in LiFePO4-Li cell, with a capacity retention of 82.4% after 200 cycles when combined with NCM622 cathode. The uniform dispersion of LLZO in PEO matrix was responsible for the improved electrochemical performance, indicating a promising pathway for the development of high energy density all-solid-state lithium batteries.
