Staged Lithiation/Delithiation of Silicon Anode in All-Solid-State Batteries Revealed by High-Stack-Pressure Operando NMR Spectroscopy
Si) permits us to capture a multistep concurrent reaction and the dynamic phase transition, which points to an asymmetric lithiation/delithiation mechanism involving four stages, including interface nucleation to bulk diffusion in lithiation and interface extraction to bulk dissolution in delithiation. Meanwhile, the operando NMR technique quantified the temperature-dependent formation rates of the silicide phases, revealing a mechanism by which temperature regulates the phase transition pathways.
