Graphene-wrapped　nitrogen-containing　carbon　spheres　(PLG)　was　fabricated　by　facile　co-pyrolysis　of　graphene　oxide　(GO)　and　polyaniline　lignosulfonate　(PL)　composite　at　800　degrees　C,　in　which　GO　was　regarded　as　skeleton,　polyaniline　was　used　as　a　nitrogen　source,　and　lignosulfonate　was　served　as　a　dispersant　and　morphology　control　agent　of　polyaniline.　The　nitrogen-containing　carbon　spheres　obtained　from　PL　precursor　not　only　acted　as　spacers　that　prevent　graphene　nanosheets　from　aggregation,　but　also　provided　high　specific　surface　area　and　channel　for　electrolyte　ions　to　reach,　playing　an　important　role　in　improving　the　electrochemical　properties　of　PLG　composite.　As　supercapacitor　electrodes,　the　graphene-wrapped　carbon　spheres　structure　of　PLG　exhibits　a　high　specific　capacitance　and　good　cycling　stability　during　repeating　cyclic　voltammetry　measurement.　A　high　specific　capacitance　of　PLG　is　presented　to　be　266.7　Fg(-1)　at　a　current　density　of　0.5　A　g(-1)　and　increased　to　103.8%　after　1000　cycles.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
