A Lithium-ion battery was prepared by controlling the content of conductive materials and the press ratio of the anode electrode to optimize cell properties. Increasing of the content of conductive material, increased the capacity, and decreased the DC-ESR. The discharge capacity retention as a function of current rates increased with an increasing amount of conductive material. With an increasing press ratio, the active material was evenly distributed on the Cu collector and a dense anode was obtained. The capacity and DC-ESR decreased with an increasing press ratio. The discharge capacity and DC-ESR retention as a function of current rates did not change remarkably with an increasing press ratio. However, the adhesion force between the Cu collector and active materials increased with an increasing press ratio.
