Microscopic observation of nanoporous Si-Li3PS4 interface in composite anodes with stable cyclability

Nanoporous Si particles, which are prepared from Mg2Si reduction of SiO2 fumes, and Li3PS4 solid electrolyte are composited to accommodate the volume expansion of Si. Cross-sectional FE-SEM and EDX measurements after charging/discharging show that nanoporous Si particles/aggregates entangle the surr...
