Current research on solid-state organic electrolytes mainly focuses on polymer electrolytes where ion transport is facilitated by chain segmental motion. A limited number of prior reports suggest that solid-state electrolytes based on organic charge-transfer (CT) complexes can have surprisingly high ionic conductivity. Here, we report that processi...

... Hence, the crystalline structure of the CT mixtures was characterized via WAXS. Figure S6a shows the WAXS pattern of LiTFSI (commercial product after drying), pure CT complex, and mixtures with different compositions. It was revealed that the CT complex had a segregated packing in which TTF and TCNQ held a face-to-face configuration within the same molecules ( Figure S6b). ...Context 2

This study explains the ionic conductivity in the mineral sugilite (idealized formula: Fe2Na2K[Li3Si12O30]) by resolving the dynamic disorder of both Li and Na cations using synchrotron X-ray single-crystal diffraction from 298 K to 1023 K. Non-zero anharmonic atomic displacement parameters at Na and Li sites at 1023 K adumbrated long-range charge...
The all‐solid‐state lithium batteries (ASSLBs) stand as a promising candidate for the next generation of high‐energy‐density batteries with superior safety. Nevertheless, achieving high energy density in ASSLBs necessitates the simultaneous realization of high active material content and loading, posing a significant challenge in ensuring effective...
Due to the increasing demand and wide applications of lithium-ion batteries, higher requirements have been placed on the energy density and safety. Polymer solid-state electrolytes have gained significant popularity due to their excellent interface compatibility and safety. However, their applications have been greatly restricted by the high crysta...
