A cathode material composed of h‐CNT/S/ZrO 2 is developed for lithium−sulfur batteries. By incorporating ZrO 2 into the S‐incorporated h‐CNT, permselective gateways for free Li + transportation can be assembled at the mesopore openings, which deny the penetration of lithium polysulfides. At the ultrahigh rate of 10 C, the discharge capacity averages to be 870 mA h g −1 within 200 cycles.
