In article number 1903125, Xing‐Long Wu, and co‐workers report a self‐supporting, flexible, additive‐free, and scalable hard carbon paper derived from tissue, which achieves outstanding Na‐storage properties in terms of high initial Coulombic efficiency (91.2%), superior high‐rate capability, ultralong cyclic stability, and outstanding low‐ T performance. In addition, its Na‐storage and capacity attenuation mechanism are also revealed.
