In article number 1601985, Xiangkang Meng and co‐workers report a general sulfidation‐controlled method for achieving novel nanosheet‐built porous tube arrays. The hierarchical architecture with permeable channels avoiding “dead volume”, rich redox reactions, and the high conductivity of the electrode material allow asymmetric devices to deliver considerably higher energy density than those reported for similar ones.
