a Scheme of the proposed SIRFB configuration. b EIS plots of the SIRFBs with GF, MoS2, and CoSA-VS/MoS2. c, d The first charge and discharge curves recorded at 15 mA cm−2 with discharged to 0.1 V (voltage cutoff) or 100% SOC (capacity cutoff) and then charged to 100% SOC (capacity cutoff) and 20 mA cm−2 with discharge to 50% SOC, respectively. e VE plots at different operational current densities with 50% SOC. f Discharge curves and the corresponding power densities with 50% SOC. g Charge and discharge polarization curves obtained at different current densities with 50% SOC. h The EE taken from galvanostatic cycling test at 20 mA cm−2 with 50% SOC.
