A　fairly　simple　and　environmentally　friendly　hydrothermal　method　is　reported　to　synthesize　anode　materials　composed　of　NiFe2O4　(NFO)　and　ultrathin　flake　graphite　(UFG),　which　are　denoted　as　NFO/UFG　composites.　Several　experiments　were　then　carried　out　in　order　to　determine　the　most　beneficial　proportion　of　UFG　in　the　composite.　Finally,　it　was　found　that　the　NFO/UFG-2　composite　exhibits　the　most　beneficial　morphological　structure　which　is　characterized　as　three-dimensional　floral　NFO　microspheres　assembled　by　many　porous　nanosheets　anchored　on　the　pedestal　of　UFG　(as　determined　from　SEM　and　TEM　measurements).　In　addition,　the　NFO/UFG-2　composite　also　demonstrates　the　best　electrochemical　performances.　It　shows　a　stable　long-term　cycling　performance　with　a　high　initial　Coulombic　efficiency　of　83.4　%　and　even　obtains　a　high　specific　capacity　of　963.4　mAh　g−1　after　300　cycles　at　a　current　density　of　200　mA　g−1　and　remarkable　reversibility　not　only　at　low　current　densities　but　also　at　high　current　densities.　Satisfyingly,　the　good　synergy　between　porous　NFO　and　UFG　significantly　enhances　the　electronic　conductivity　and　relieves　the　huge　bulk　expansion　of　traditional　transition　metal　oxide.　This　unique　electrode　material　is　demonstrated　to　be　a　promising　candidate　for　the　new-generation　lithium　ion　batteries.　©　2017　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
