The　ultrathin,　ternary　nickel　cobaltite　(NiCo2O4)　nanosheets　supported　on　Nickel　foam　(NF)　were　prepared　via　a　facile　two　step　process,　which　includes　electrodeposition　method　combined　with　a　thermal　treatment.　The　scanning　electron　microscopy　(SEM)　and　transmission　electron　microscopy　(TEM)　characterisation　of　as-prepared　material　demonstrates　the　nanostructure　grown　on　Ni　foam　is　consisted　of　NiCo2O4　layer　and　NiCo2O4　nanosheets.　The　as-prepared　samples　are　directly　fabricated　as　electrodes　for　supercapacitors,　and　the　outstanding　electrochemical　performance　of　2517　F　g(-1)　is　achieved　at　1　A　g(-1)　with　a　mass　loading　of　1.2　mg　cm(-2).　The　cyclic　stability　is　also　tested　under　current　density　of　8　A　g(-1),　and　64%　of　initial　capacitance　is　still　maintained　after　800　cycles.　The　excellent　electrochemical　performance　of　the　as-prepared　nanosheets　suggests　their　promising　application　as　supercapacitor　electrode　material.
