dc.description.abstract | The challenge of safety problems in lithium batteries caused by conventional electrolytes at high temperatures is addressed in this study. A novel solid electrolyte (HKUST‐1@IL‐Li) was fabricated by immobilizing ionic liquid ([EMIM][TFSI]) in the nanopores of a HKUST‐1 metal– organic framework. 3D angstrom‐level ionic channels of the metal–organic framework (MOF) host were used to restrict electrolyte anions and acted as “highways” for fast Li+ transport. In addition, lower interfacial resistance between HKUST‐1@IL‐Li and electrodes was achieved by a wetted contact through open tunnels at the atomic scale. Excellent high thermal stability up to 300 °C and electrochemical properties are observed, including ionic conductivities and Li+ transference numbers of 0.68 × 10‐4 S∙cm‐1 and 0.46, respectively, at 25 °C, and 6.85 × 10‐4 S∙cm‐1 and 0.68, respectively, at 100 °C. A stable Li metal plating/stripping process was observed at 100 °C, suggesting an effectively suppressed growth of Li dendrites. The as‐fabricated LiFePO4/HKUST‐ 1@IL‐Li/Li solid‐state battery exhibits remarkable performance at high temperature with an initial discharge capacity of 144 mAh g‐1 at 0.5 C and a high capacity retention of 92% after 100 cycles. Thus, the solid electrolyte in this study demonstrates promising applicability in lithium metal batteries with high performance under extreme thermal environmental conditions. © 2021 by the author.
