The back cover picture shows the materials used by Park et al. to produce a renewable hybrid electrode: it consists of lignin nanocrystals confined on reduced graphene oxides (RGOs). Using this electrode results in a large maximum capacitance (432 F g −1 ), which is close to the theoretically obtainable value of 482 F g −1 and sixfold higher than that of RGO (93 F g −1 ). Remarkable rate and cyclic performances are also achievable. The excellent capacitive performance is attributed to the fast and reversible pseudocapacitive behavior of quinone moieties and the synergistic interplay between lignins and RGOs. More details can be found in the Full Paper by Park et al. on page 1094 (DOI: 10.1002/cssc.201301061 ).
