A　three-dimensional　conductive　network-based　ordered　polyaniline　(PANI)　nanorods/graphitic　mesoporous　carbon　(GMC)　composite　is　successfully　fabricated　by　the　introduction　of　PANI　into　a　low-cost　GMC　with　a　highly　fluffy　and　porous　structure,　and　the　effects　of　the　GMC　content　on　the　electrochemical　performance　are　investigated　using　the　as-prepared　composite　as　active　material.　Results　show　that　the　unique　structure　of　the　composite　is　beneficial　to　ion　and　electron　transport　as　well　as　redox　reactions　during　charge-discharge　process.　The　composite　containing　15　wt%　GMC　exhibits　a　high　specific　capacitance　of　715　F　g(-1)　at　a　current　density　of　1　A　g(-1)　and　remains　429　F　g(-1)　at　10　A　g(-1)　(60.0%　retention).　Furthermore,　the　composite　shows　excellent　cycling　stability　with　a　high　capacitance　retention　of　up　to　93.6%　at　100　mV　s(-1)　after　10000　cycles,　and　exhibits　a　coulombic　efficiency　in　excess　of　90%　after　2500　cycles　at　a　current　density　of　3　A　g(-1).　More　importantly,　the　composite　presents　a　high　energy　density　of　24.64　W　h　kg(-1)　at　a　power　density　of　250　W　kg(-1)　and　13.79　W　h　kg(-1)　at　5000　W　kg(-1),　which　is　highly　competitive　with　other　reported　PANI/carbon　composite　electrodes.
