The　novel　hierarchical　Ni-Co　sulfide　nanosheet-nanotubes　arrays　were　directly　grown　on　Ni　foam,　as　binder-free　electrodes,　have　been　successfully　synthesized　following　a　one-step　facile　hydrothermal　method　combined　with　a　sulfide　treatment.　The　initial　value　of　the　area　capacitance　achieved　2.28　F　cm(-2)　at　a　current　density　of　1　mA　cm(-2).　A　high　areal　capacitance　retention　of　95.2%　compared　to　activation-induced　peak　value　is　achieved　after　3000　charge-discharge　cycles,　which　is　much　better　than　counter　Ni-Co　oxide　electrode　(1.75　F　cm(-2)　at　1　mA　cm(-2),　93.2%　retention　compared　to　activation　induced　peak　value).　The　outstanding　and　excellent　super　capacitive　performance　is　ascribed　to　ion-exchange　reaction,　which　induces　a　flexible　hollow　nanotube　feature　and　show　higher　conductivity,　compared　with　Ni-Co　oxide　NWs.　Cyclic　voltammetry　(CV)　and　Electrochemical　impedance　spectra　(EIS)　results　confirmed　that　the　synthesized　electrode　contains　the　lowest　resistance　at　high,　and　at　lower　frequency,　leading　to　easy　penetration　of　electrolytes　and　fast　transportation　of　electrons　inside　the　electrode.　In　this　proposed　work,　a　one-step　hydrothermal　method　has　been　followed,　and　provided　for　the　sulfide-induced,　with　a　noticeable　electrochemical　performance　of　nickel　cobaltite　compounds　and　supplying　a　promising　route　for　high-performance　supercapacitor　electrodes.
