报告摘要
Although 3D structural carbon networks materials have shown good performance in potassium ion batteries (KIBs), it is noticeable that the 3D networks are indigested and the unit material that makes up the 3D network is one-dimensional carbon nanotube or graphitic carbon. In this work, we report a novel integrated three-dimensional amorphous carbon encapsulated cobalt sulfide/Nitrogen-doped carbon nanotubes/CoS coated carbon nanofibers networks composed of independent 3D hierarchical structure units. The unique 3D orderly electrode bracket design reduces ion diffusion path and improves electronicconductivity and mechanical stability, while CoS nanoparticles participate in K+ insertion/extraction, which is advantageous to high performance energy storage. Specifically, the AC@CoS/NCNT/CoS(@CNFs is further evaluated as anode for potassium ion battery obtained the capacity of 401 mA h g-1 at 3.2 A g-1 after 100 cycles with outstanding rate capabilities better than other reported MOFs as anode materials for potassium ion batteries literatures. In addition, the capacity maintained of 130 mA h g-1 at 3.2 A g-1 after 600 cycles with excellent cycling stability, opening a new direction for the fabrication of 3D structure anodes for alkali metal ion battery anodes applications.
