Synthesis of CuO nanostructures from Cu-based metal organic framework (MOE-199) for application as anode for Li-ion batteries

We report the synthesis of CuO nanostructures by metal organic framework (MOF) based approach. Spherical shaped, phase pure CuO nanoparticles are obtained by controlled pyrolysis of Cu-based MOF. Electrochemical properties are evaluated in half-cell assembly and it is found that similar to 1.6 mol of Li (similar to 538 mAh g(-1)) is cycleable via conversion reaction. Further, MOF derived CuO retained 90% of initial reversible capacity after 40 cycles. Rate performance studies showed the deliverable reversible capacity of similar to 210 mAh g(-1) at high current rate of 2 A g(-1). (C) 2013 Elsevier Ltd. All rights reserved.
