•Li4Mo5O17 was first investigated for lithium-ion battery anode.•Li4Mo5O17 micron particles were prepared by citric acid aid sol-gel method.•Li4Mo5O17 electrode shows stable long cycle life. Herein, the micron-sized lithium molybdenum oxide (Li4Mo5O17, LMO) is first investigated as a new anode material for lithium secondary battery. LMO was obtained through citric acid aid sol–gel method and subsequently characterized by X-ray diffraction, X-ray photo-electron spectrometer and scanning electron microscopy. When tested as anode materials for lithium-ion batteries, the LMO electrode demonstrates excellent electrochemical performance. The initial discharge and charge specific capacities were 1470 mAh g−1 and 845 mAh g−1 at the current density of 100 mA g−1, respectively. The electrode provides a reversible charge capacity of 507 mAh g−1 even after 600 cycles long life test. These data show that LMO is very promising for the next generation of lithium-ion batteries.
