The　development　of　conversion-typed　anodes　with　ultrafast　charging　and　large　energy　storage　is　quite　challenging　due　to　the　sluggish　ions/electrons　transfer　kinetics　in　bulk　materials　and　fracture　of　the　active　materials.　Herein,　the　design　of　porous　carbon　nanofibers/SnS2　composite　(SnS2@N-HPCNFs)　for　high-rate　energy　storage,　where　the　ultrathin　SnS2　nanosheets　are　nanoconfined　in　N-doped　carbon　nanofibers　with　tunable　void　spaces,　is　reported.　The　highly　interconnected　carbon　nanofibers　in　three-dimensional　(3D)　architecture　provide　a　fast　electron　transfer　pathway　and　alleviate　the　volume　expansion　of　SnS2,　while　their　hierarchical　porous　structure　facilitates　rapid　ion　diffusion.　Specifically,　the　anode　delivers　a　remarkable　specific　capacity　of　1935.50　mAh　g(-1)　at　0.1　C　and　excellent　rate　capability　up　to　30　C　with　a　specific　capacity　of　289.60　mAh　g(-1).　Meanwhile,　at　a　high　rate　of　20　C,　the　electrode　displays　a　high　capacity　retention　of　84%　after　3000　cycles　and　a　long　cycle　life　of　10　000　cycles.　This　work　provides　a　deep　insight　into　the　construction　of　electrodes　with　high　ionic/electronic　conductivity　for　fast-charging　energy　storage　devices.
