Many researches on binder-free electrodes for lithium ion batteries have been conducted which electrode have good adhesion to the current collector and improve the energy density by not using an insulating binder. However, in many binder-free electrode researches, areal capacity is relatively low compared to gravimetry capacity because the thickness of the electrode is thin with low mass of the active materials.
In this study, binder-free CuO nanostructures were fabricated by in-situ growth precipitation followed by thermal annealing under air atmosphere. When evaluated as binder-free CuO electrodes annealed at 550 °C, this electrode exhibits a high gravimetry capacity(653 mAh/g at 100 mA/g and 411 mAh/g at 500 mA/g) as well as high areal capacity (1371 μAh/cm2 and 863 μAh/cm2) at with high coulombic efficiency and good cycling stability.
