原始语种摘要: Abstract(#br)The conventional liquid electrolytes (LEs) have a high level of ionic conductivity; however, they often suffer from the poor processability and safety risks of potential leakage. Although solid-state electrolytes (SSEs) can solve these inherent problems of LEs, the ionic conductivity of most SSEs is several magnitudes lower than these of LEs. Herein, we report a novel strategy by building liquid ion-transport channels in a solid framework and prepared an electrolyte-locked separator (ELS) using a collagen fiber membrane (CFm). The liquid electrolyte was primarily infiltrated in the smaller voids of CFm, and its ionic conductivity could attain to 9.0 × 10 −3 S cm −1 when the electrolyte absorption ( E A ) reached up to 112.0%. After centrifuging treatment, the electrolyte...
