Fig. 2

a Cross-sectional schematic of the electrochemical cell for operando XAS, showing the a-Si(20 nm)/Ni(20 nm) and Li electrodes and the LP30 electrolyte. A Si3N4(100 nm) membrane is used as the X-ray transparent window and the electrodes are connected to an external circuit allowing operando cycling. TEY-XAS is enabled by measuring the current generated under X-ray illumination, employing a beam-chopper and lock-in amplifier set-up to separate faradaic and TEY currents. b Deconstructed 3D cell design, showing the positions of the O-rings, flanges, membrane, Li electrode and separator. c Photograph of operando cell in the experimental setup.
