Zinc-cobalt　double-metal　sulfides　(ZCSs)　with　kinds　of　structures　as　electrode　materials　play　an　essential　role　in　supercapacitors　(SCs).　However,　their　poor　electronic　transfer　efficiency　and　irreversible　structural　damage　greatly　affect　their　practical　applications.　The　idea　of　high　structural　stability　and　bimetal　synergy　(Zn-Co)　is　introduced　to　prepare　high-perform-ance　electrodes　and　construct　hybrid　supercapacitors.　A　unique　graphite　sheet-supported　ZCS　nanoparticle　is　grown　on　porous　Ni　foam　(GZCS/NF)　by　a　facile　hydrothermal　and　ion-exchange　reaction.　The　unique　nanosheet　structure　with　a　nanosheet　of　about　80　nm　exhibits　a　specific　capacity　of　1293.5　C　g(-1)　at　1　A　g(-1),　a　relatively　low　charge-transfer　resistance　of　0.16　Omega,　and　superior　cycling　stability,　which　can　be　attributed　to　the　excellent　pseudocapacitive　capacity　of　ZCS　nanoparticles　and　the　good　chemical　stability　of　the　graphite　sheet.　A　hybrid　supercapacitor　in　KOH　solution　is　assembled　with　GZCS/NF　as　the　cathode　and　AC　as　the　anode.　The　assembled　GZCS/NF//AC　HSC　delivers　a　wide　working　voltage　of　1.7　V　and　a　specific　capacity　of　196.4　C　g(-1)　at　1　A　g(-1).　Its　ability　to　light　up　eight　red　LEDs　for　about　7　min　proves　its　good　prospects　in　energy　storage　devices.
