[en] A spindle-like Cu-based metal-organic framework was successfully synthesized under microwave-assisted reaction. When treated as a precursor by pyrolysis of this Cu-MOF at 700 °C under air atmosphere, porous hollow CuO/C composites were prepared and tested as an anode material for lithium-ion batteries (LIBs). The CuO/C electrode manifests an excellent specific capacity of about 789 mAh g−1 at a current of 100 mA g−1 after 200 cycles, together with superior cyclic stability and remarkable rate capacity, which is supposed to benefit from the large accessible surface area and unique hollow interior structure. The remarkable performances make it a promising anode material for LIBs. - Graphical abstract: Spindle-like hollow CuO/C was successfully synthesized by calcination of a Cu-based metal-organic framework as template. When evaluated as an anode material for lithium-ion batteries, the CuO/C electrode delivers a reversible discharge capacity of about 789 mAh g−1 at a current of 100 mA g−1 after 200 cycles. Moreover, it also exhibits superior cyclic stability and good rate capacity. The results suggest the promising application as an advanced anode material. - Highlights: • Spindle-like CuO/C was synthesized for Li-ion battery by annealing of a Cu-based MOF. • CuO/C-700 shows superior electrochemical performance to CuO/C-500 and CuO/C-900. • CuO/C-700 electrode delivers a reversible capacity of 789 mAh g−1 after 200 cycles.
