Micro CuO crystals are synthesized by hydrothermal method in one step. The CuO-Li ion full battery is assembled using the porous lithium foil-graphite as a anode and the prepared CuO crystals as a cathode. The micro CuO crystals are characterized by scanning electron micro porousscopy, X-ray powder diffractometer, Fourier Transform infrared spectrometer, thermogravimeter, Brunauer–Emmett–Teller surface area measurements, and differential scanning calorimeter. The full battery is tested by the galvanostatic current charge-discharge technology at higher current densities of 0.25–0.5 mA/cm². The porous lithium foil-graphite anode can effectively inhibit the powder of anode lithium, and improve the reversibility of the battery.
