Self-Assembled Carbon Metal-Organic Framework Oxides Derived from Two Calcination Temperatures as Anode Material for Lithium-Ion Batteries.

ABSTRACT: Owing to their structural diversity and mesoporous construction, metal-organic frameworks (MOFs) have been used as templates to prepare mesoporous metal oxides, which show excellent performance as anode materials for lithium-ion batteries (LIBs). Co-ZnO/C and Co-Co₃O₄/C nanohybrids were successfully synthesized based on a precursor of Co-doped MOF-5 by accurately controlling the annealing temperature and atmosphere. Experimental data proved that their electrochemical performance was closely associated with the material phase, especially for Co-ZnO/C, indicating that carbon skeleton materials can maintain a good restoration rate of over 99% after undergoing high-current density cycling. Meanwhile, Co-Co₃O₄/C nanohybrids showed an exceedingly high
