Merged summary
TL;DR - Researchers developed an electron-cloud-homogenized MOF electrolyte that enables solid-state lithium batteries to operate below −60°C. The approach sharply lowers ion-transport barriers and could generalize to other low-temperature ionic conductors.
- The ECH-MOF electrolyte achieves a 0.045 eV activation energy and 1.2×10⁻⁵ S·cm⁻¹ lithium-ion conductivity at −60°C.
- Electron-withdrawing cyano ligands redistribute electron density to create a continuous, low-barrier Li⁺ transport pathway.
- The authors attribute transport to a quantum-tunneling-like sliding mechanism rather than conventional thermally activated hopping.
- An NCM811‖Li cell delivered 109.2 mAh·g⁻¹ at −60°C and 1C, retaining 62% capacity after 1,000 cycles; operation was also demonstrated at −90°C.
