The 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.
