A (NiMnCo)-Metal-Organic Framework and its oxidized and pyrolysed derivatives have been tested as electrode materials for lithium-ion batteries. Materials have been fully characterized by Scanning Electron Microscopy (SEM), powder X-Ray Diffraction (XRD), Thermogravimetric Analyses (TGA), Infrared (IR) spectroscopy and electrochemical properties have been determined in coin cells using lithium metal as the counter electrode. Studies have revealed specific capacities of 860 mAh g−1 and 800 mAh g−1 at 15 mA g−1 respectively for the MOF and the oxide (690 and 190 mAh g−1 after 50 cycles) whereas the corresponding pyrolysed compound has shown limited electrochemical performances. Ex situ XRD has been performed to highlight the evolution of the material structure during cycling. These results show that electrochemical storage is based on a conversion reaction.
