Extended Data Fig. 8: Morphology and chemistry of SiG anode after discharging at low operational pressure.
From: Fast cycling of lithium metal in solid-state batteries by constriction-susceptible anode materials
The FIB-SEM (a,b) and EDS mapping (c) of SiG anode after discharging at 5 MPa. The battery is with the structure of SiG-LPSCl-LGPS-LPSCl-NMC83 (loading = 25 mg/cm2) with a nominal NP ratio of 1.5 and was cycled at room temperature at 0.5 C. (d) Pouch cell with the structure of Li-SiG-SEs-NMC83 (loading = 15 mg/cm2) cycled at 5C charge and discharged at 5 MPa and 55 ℃, with initial areal capacity = 1.36 mAh/cm2.
