3D porous nanoarchitectures derived from SnS/S‐doped graphene hybrid nanosheets are successfully prepared by controllable thermal conversion of oleylamine‐capped mixed‐phase SnS 2 ‐SnS nanodisks precursors, and employed as electroactive material to fabricate flexible, symmetric, all‐solid‐state supercapacitors. The fabricated solid devices exhibit very high areal specific capacitance (2.98 mF cm −2 ), good cycling stability (99% for 10 000 cycles), excellent flexibility, and desirable mechanical stability.
