Abstract

The porous Co 3 O 4 with electrospun carbon (Co 3 O 4 /C) was synthesized simply through annealing the Co-based metal-organic-framework/polyacrylonitrile (ZIF-67/PAN) templates. The samples were characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM) and Brunauer-Emmett-Teller (BET) techniques. The content of electrospun carbon in Co 3 O 4 /C was tested by thermogravimetric analysis (TG). The Co 3 O 4 /C not only shows a remarkable capacity of 1024.1 mAh g −1 after 100 cycles but also behaves superior rate capability. The superior electrochemical properties could be attributed to the electrospun carbon, which serves as a buffer layer to slow down the volumetric stresses and provides conductive paths for fast Li + diffusion and easy electric charge transfer. Therefore, superior performance of the Co 3 O 4 /C electrode makes it possible to be used as promising anode for lithium ion battery application.
