Modulating Lattice Oxygen and Transport Kinetics of Li‑Rich Cathodes in All‑Solid‑State Batteries Through Multifunctional Li3ScF6 Protective Layer (IMAGE)
Caption
- A multifunctional Li3ScF6 protective layer is engineered to simultaneously modulate lattice oxygen stability and interfacial transport kinetics of Li-rich cathodes in all-solid-state batteries.
- The Li3ScF6 layer significantly enhances interfacial contact between Li-rich Mn based oxide and the solid electrolyte, suppressing parasitic interfacial reactions and facilitating faster Li+ transport across the interface. Concurrently, the strong Sc–O bonding stabilizes the lattice oxygen framework, suppresses oxygen evolution, and improves the reversibility of oxygen-anion redox.
- The well-configured cells exhibit outstanding electrochemical performance, enabling fast charging, long-term cycling stability, and stable operation at high areal capacities in all-solid-state batteries.
