Breakthrough in precision electrodeposition technology brings copper foil production quality to a new level

The application of precision electrodeposition technology in Cathode Drum directly affects the deposition quality of the copper layer during the production of copper foil. Although traditional electrolytic deposition technology has been used for many years, due to problems such as uneven current distribution and unstable distribution of copper ions during the deposition process, defects often appear on the surface of the copper foil, such as uneven thickness, rough or irregular surface structure, which greatly affect the quality of the copper foil and the overall performance of the battery.
Cathode Drum has made innovative breakthroughs in this regard, ensuring the uniformity and stability of the copper foil through precise current control and electrodeposition parameter adjustment. Especially in the optimization control of current distribution and electrolyte flow direction, the design of Cathode Drum enables copper ions to be deposited more evenly on the surface of the titanium drum, thereby effectively avoiding the phenomenon of uneven copper layer deposition common in traditional electrodeposition technology.

The thickness uniformity of copper foil is an important factor affecting the performance of lithium batteries. In traditional copper foil production, due to the inaccuracy of the electrodeposition process, the thickness of the copper foil is often difficult to control, resulting in local weak areas on the surface, which affects the conductivity and stability of the battery. Cathode Drum successfully solved this problem through precision electrodeposition technology.
In traditional processes, the thickness of copper foil fluctuates greatly, which may cause undesirable conditions such as current imbalance or heat concentration inside the battery. Cathode Drum uses high-precision current regulation technology to make the deposition process of copper ions in the electrolyte more stable, thereby ensuring that the copper foil maintains a consistent thickness throughout the production process. The thickness tolerance of each piece of copper foil is precisely controlled, which greatly improves the uniformity of the copper foil and ensures its good conductivity and reliability in lithium batteries.

The surface quality of copper foil also plays a vital role in the performance of lithium batteries. In the traditional copper foil production process, due to the limitations of electrodeposition technology, the surface of copper foil often has unevenness, roughness or tiny defects. These surface problems not only affect the aesthetics of the copper foil, but also may affect its contact effect with other battery components, thereby affecting the stability and life of the battery.
Cathode Drum successfully solved this problem by optimizing precision electrodeposition technology. With the support of this technology, the surface of the copper foil can remain highly flat and smooth. Precision current control and temperature regulation make the deposition process of copper ions in the electrolyte more uniform, and there will be no excessive particles or uneven deposition layers during the formation of the copper layer. In this way, the surface finish of the copper foil is greatly improved, effectively avoiding the impact of surface defects on the performance of lithium battery electrodes.

The conductivity and mechanical strength of copper foil are crucial to the performance of lithium batteries. In the traditional copper foil production process, the conductivity and mechanical strength of copper foil are often affected by the uneven deposition of the copper layer and the defects of the microstructure. The precision electrodeposition technology of Cathode Drum optimizes the deposition conditions and current control to make the crystal structure of the copper layer more uniform, thereby effectively improving the conductivity and mechanical properties of the copper foil.
Cathode Drum's electrodeposition process promotes the ideal arrangement of the copper foil crystal structure by precisely controlling the current density and electrolyte temperature, avoiding the crystal defects commonly found in traditional production processes. This enables the copper foil to maintain a higher conductivity during the charge and discharge process of the battery. At the same time, the mechanical strength of the copper foil is also enhanced, and it has better deformation resistance and durability during battery use.

Cathode Drum also improves overall production efficiency and reduces production costs through its precision electrodeposition technology. In the traditional electrolytic copper foil production process, production efficiency is often limited due to uneven copper layer deposition, long downtime and high scrap rate. Through precision electrodeposition technology, Cathode Drum can accurately control the electrodeposition process, thereby reducing scrap rate and improving production efficiency. Cathode Drum's technical advantages are reflected in the improvement of quality and the control of production costs. Because the deposition process of the copper layer is more uniform, the use of electrolyte and current in the production process is more efficient, which saves energy consumption and reduces production costs. At the same time, the qualified rate of copper foil products has increased, which has also reduced losses in the entire production process, further improving the economic benefits of production companies.
