Transitional　metal　selenides　are　considered　as　potential　anode　candidates　for　sodium-ion　batteries　(SIBs)　because　of　their　relatively　high　theoretical　capacity　and　environmental　benign.　However,　the　large　volume　change　derived　from　the　conversion　reaction　and　the　sluggish　kinetics　due　to　the　inherent　low　electrochemical　conductivity　hinder　their　practical　application.　Herein,　composite　materials　of　NiSe2　encapsulated　in　nitrogen-doped　TiN/carbon　nanoparticles　with　carbon　nanotubes　(CNTs)　on　the　surface　(NiSe2@N-TCP/CNTs)　are　fabricated　via　pyrolysis　and　selenization　processes.　In　this　composite,　TiN　inside　the　carbon　matrix　can　enhance　the　conductivity　and　structural　stability.　CNTs　that　are　in-situ　grown　on　the　surface　not　only　further　enhance　the　conductivity　of　the　composites,　but　also　offer　sufficient　space　to　buffer　the　volume　expansion　and　alleviate　serious　aggregation　of　NiSe2　nanoparticles.　Benefit　from　these　merits,　the　NiSe2@N-TCP/CNTs　showed　a　lower　charge　transfer　resistance　and　a　faster　Na+　diffusion　rate　than　materials　without　growing　CNTs.　When　used　as　the　anode　of　SIBs,　the　NiSe2@N-TCP/CNTs　electrode　delivered　a　reversible　capacity　of　344.0　mAh　g(-1)　after　1000　cycles　at　0.2　A　g(-1),　and　still　maintained　at　272.7　mAh　g(-1)　even　at　a　high　current　density　of　2　A　g(-1).　The　remarkable　electrochemical　performance　is　mainly　attributed　to　the　special　designed　hierarchical　structures　and　pseudo　capacitance　sodium　storage　behavior.
