In　this　study,　graphene/polypyrrole　(RGO/PPy)　electrodes　with　porous　structures　were　prepared　by　electrochemical　codeposition　and　reduction.　The　porous　structure　not　only　enhances　the　effective　contact　area　of　the　electrodes　but　also　actively　promotes　the　diffusion　efficiency　of　the　electrolyte　ions.　As　a　result,　a　maximum　capacitance　of　1091.2　mFcm(-2)　at　1　mAcm(-2)　is　achieved　for　the　0.2-RGO/PPy　electrode　prepared　using　the　deposition　solution　containing　0.2　mgmL(-1)　of　GO.　The　0.2-RGO/PPy　maintains　a　capacitance　of　78.4%　at　10　mAcm(-2).　In　particular,　the　0.2-RGO/PPy-based　supercapacitor　exhibits　a　stack　capacitance　of　up　to　28.3　Fcm(-3).　Furthermore,　the　supercapacitor　exhibits　excellent　mechanical　flexibility　with　a　93.3%　capacitance　retention,　even　under　180　degrees　bending.　This　study　demonstrates　the　significant　potential　of　RGO/PPy　electrodes　for　high-performance　energy　storage　systems.
