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