(a) The voltage profiles in the 2nd charge-discharge cycle and (b) cycling performance at the rate of 0.1 C–0.3 C of LSBs with different overlayers incorporated in the cathode. (c) Charge-discharge voltage profiles in different cycles for the NCS/EOG/CNF cell. (d) Long-term cycling performance of the NCS/EOG/CNF cell at 1 C. (e) Charge-discharge curves in the 2nd cycle and (f, g) cycling performance of NCS/EOG/CNF cells with different sulfur loadings of 2, 4, and 6 mg·cm−2.
