The C/S cathode with only 0.5 wt % binder, composed with Nafion and PVP, was assembled layer-by-layer for lithium-sulfur battery (Li-S) application. It achieved excellent binding strength and battery performance compared to the cathode with 10 wt % PVDF, which is promising to further increase the practical energy density of Li-S batteries.
