【 摘 要 】

tsThe composite gel electrolyte with low tortuosity ion-conducting arrays (GPE/ICAs) exhibiting high room-temperature ionic conductivity (1.08 mS cm−1) was successfully prepared by directionally growing ice crystals and in-situ polymerization.The stable and rapid Li+ migration through ICAs in the GPE is proved by 6Li solid-state nuclear magnetic resonance and synchrotron radiation X-ray diffraction combined with computer simulations.Li/LiFePO4 full cells using GPE/ICAs exhibit excellent cycle performance and high-capacity retention at wide temperature (0–60 °C), which has the potential towards all-weather practical solid-state batteries.
