A cationic chain-anchored monolayer in poly(vinylidene fluoride-co-hexafluoropropylene)/garnet composite polymer electrolytes enables low-barrier lithium-ion transport with 0.092 eV activation energy and Li+ transference number 0.78.
- Why it matters: Efficient ionic conduction that stays stable at interfaces across wide temperatures is a key barrier to safe, high-capacity solid-state lithium-metal batteries.
- What they did: The authors engineered solvent-phobic, chain-tethered cationic channels and tracked their evolution using synchrotron infrared spectroscopy, 2D solid-state NMR, and operando measurements.
- The result: The electrolytes show 400 cycles at 120 °C with >99% capacity retention in Li||LiFePO4 and 450 cycles at -25 °C with 82.5% capacity retention in 4.5 V Li||LiNi0.8Co0.1Mn0.1O2.
