a Fitted lines of oxidation peak for S/Ga-Cd DAs-HMCS cathode and three control groups (S/Ga SA-HMCS, S/Cd SA-HMCS and S/HMCS) between Ip and v1/2. b Optical photographs of visualized adsorption tests (K2S6) and UV-vis spectra of Ga-Cd DAs-HMCS, Ga SA-HMCS, Cd SA-HMCS and HMCS samples. c The shuttle currents of S/Ga-Cd DAs-HMCS cathode and three control groups. d The potentiostatic discharge curves of Ga-Cd DAs-HMCS, Ga SA-HMCS, Cd SA-HMCS and HMCS samples (K2S6-EC). e, f The in situ UV-vis spectra of S/Ga-Cd DAs-HMCS and S/HMCS cathodes during the first cycle (specific current of 0.2 A g−1, test temperature of 28 °C). g Comparison of the radar chart for the S/Ga-Cd DAs-HMCS cathode and three control groups. Source data for a–g were provided as a Source Data file.
