In Situ Partial‑Cyclized Polymerized Acrylonitrile‑Coated NCM811 Cathode for High‑Temperature≥100 °C Stable Solid‑State Lithium Metal Batteries (IMAGE)
Caption
- Uniform and stable interfacial layer with both ionic and electronic conduction on the surface of solid-state composite cathode by in situ polymerization cyclization treatment.
- Theoretical calculations demonstrate that cPAN can effectively inhibit transition metal dissolution and uneven cyclic stress distribution and improve the stability of the crystal structure.
- In-cPAN-260@NCM811 has excellent cycling performance with 86.8% retention after 300 cycles and thermally safe stability at high-temperature extremes.
