(a) Asymmetric load cell setup used to lower the cathode stack pressure while maintaining anode pressure. Corresponding voltage capacity curves for a cell cycled at 0.2 mA cm–2 and an anode/cathode pressure of 2.5 MPa/0.2 MPa for a (b) SC-NMC/LPSCl composite cathode of 14 mg cm–2 (3 mA h cm–2), and capacity fade compared to different pressures and a (c) SC-NMC/LPSCl composite cathode of 43 mg cm–2 (8.7 mA h cm–2). (d) Discharge capacity comparison for Ni-rich composite cathodes pressed at RT as a function of the stack pressure during cycling.
