| Abstract: | In order to prevent the aggregation of ZIF-67, increase the electrochemical reaction sites, promote the diffusion of lithium-ions, improve the cycling stability of the electrode, and avoid the negative impact of conductive agents and binders, a copper-supported network with ZIF-67 derivative encapsulated in a carbon matrix was synthesized by sintering the copper foil coated by the suspension containing ZIF-67, polyacrylonitrile (PAN), polymethyl methacrylate (PMMA), and N-dimethylformamide (DMF). The obtained copper-supported coating is CoOx/C composite. Being sintered in an inert atmosphere at high temperature, ZIF-67 decomposes to form Co3O4/C composite, PAN decomposes to form carbon, and PMMA volatilizes. The volatilization of PMMA at high temperatures leads to the network structure of the ZIF-67 derivative/PAN-derived carbon coating. The ZIF-67 derivative/PAN-derived carbon coating exhibits a high capacity of 1149 mAh g−1 and good cycling stability. Its good electrochemical performance depends on the following factors: (1) the steric hindrance effect of PAN-derived carbon avoids the aggregation of the ZIF-67 derivative; (2) the copper-supported coating is free of conductive agents or binders; (3) the network structure is beneficial for increasing the electrochemical reaction sites for lithium storage, promoting the diffusion of lithium-ions, and improving the cycling stability of the electrode.
