Abstract:

Co/Zn bimetal organic framework precursor (Co/Zn-MOF-74) has been obtained by using the one-step facile microwave-assisted solvothermal method. By calcining the Co/Zn-MOF-74 at 500 ${^\circ}$C under air, the mesoporous mixed-metallic Co-Zn-O microrod can be obtained. When applied as the anode materials for lithium-ion batteries, the Co-Zn-O electrode exhibits good electrochemical properties (reversible capacity of 1 137 mA$\cdot$h$\cdot$g-1 after 100 cycles), which could be attributed to its mesoporous nanostructure along with the synergistic effects between two different metal species.

Key words: metal-organic frameworks, mixed-metal oxide, lithium-ion batteries, anode material
