A superelastic and active graphene aerogel with nitrogen and boron co-modification is developed by a simple naturally drying post-process. The resulting aerogel owns a robust three-dimensional architecture which exhibits highly repeatable compressibility even under 80% strain. In addition, the aerogel material offers a high specific capacitance of 336 F g−1 at 0.25 A g−1, the energy density of 13...
