On page 3774, C. Zhou and co‐workers show that by incorporating a fine amount of ZrO 2 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 an ultrahigh rate of 10C.
