Supercapacitors: Packing Activated Carbons into Dense Graphene Network by Capillarity for High Volumetric Performance Supercapacitors (Adv. Sci. 14/2019)

In article number 1802355, Ying Tao, Quan‐Hong Yang, and co‐workers develop a densification strategy of activated carbons inspired by the dense structure of pomegranate grains. The carbon particles as “grains” are compactly packed in a capillary shrinking graphene network where reduced graphene oxides are “peels”.
