CoO　has　been　considered　as　a　novel　anode　material　for　lithium　storage　due　to　its　high　theoretical　capacity.　Herein,　mesoporous　3D　CoO/nitrogen-doped　graphene　aerogel　(CoO/NGA)　is　constructed　by　a　facile　solvothermal　approach　followed　by　subsequent　annealing.　The　NGA　is　prepared　by　using　dimethylmethanamide　(DMF)　as　a　reducing　agent　and　nitrogen　source,　Ultrafine　Coo　nanocrystals　are　homogeneously　distributed　and　tightly　anchored　on　the　3D　macroscopic　NGA　frameworks.　The　3D　NGA　can　not　only　effectively　restrain　the　agglomeration　of　CoO　nanocrystal　but　also　accelerate　ion　and　electron　transport　through　3D　networks.　Benefiting　from　the　combine　of　the　two　characteristics,　the　unique　CoO/NGA　anode　exhibits　an　outstanding　cycling　stability,　showing　a　specific　capacity　of　896　mAh　g(-1)　at　200　mA　g(-1)　after　200　cycles.
