Cyclic voltammogram profiles. a CV profiles comparison; CV profiles at different scan rates of lithium-sulfur cells with b CMC/G cathode and c CMC cathode; d the linear fits (R2 = 0.99) of the CV peak currents for the lithium-sulfur cells with CMC/G cathode (A1, B1, C1) and with CMC cathode (A2, B2, C2). Charge/discharge profiles corresponding of lithium-sulfur cells with e CMC/G cathode and f CMC cathode. Electrochemical impedance spectroscopy g Nyquist plots of the lithium-sulfur cells with CMC/G and CMC cathodes before and after 80 cycles; h Nyquist plot and equivalent circuit fitting of cells after cycling.
