On page 3774, C. Zhou and co‐workers show that by incorporating a fine amount of ZrO2 around the mesopore openings of S‐impregnated holey carbon nanotubes (CNTs), permselective gateways are formed that not only allow free Li+ transportation but also deny the dissolution of lithium polysulfides. The designed architecture provides a stable discharge capacity of about 870 mA h g−1 within 200 cycles under...
A cathode material composed of h‐CNT/S/ZrO2 is developed for lithium−sulfur batteries. By incorporating ZrO2 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.
