Electrochemical performance of the modified hollow carbon nanofiber cathode. (a) Specific capacities of the PVP modified sulfur cathode at C/5, C/2 and 1C cycling rates. (b) Comparison of cycling performance at C/2 with and without the PVP modification. Credit: ACS, Zheng et al. Click to enlarge. Lithium sulfur batteries are of great interest due to their high specific energy and relatively low cost (e.g., earlier post ).
