The Key Role of Activated Carbon in the Purity of Copper Foil Electrolyte

Copper foil is a critical conductive material in lithium-ion batteries and printed circuit boards. However, the purity of the copper foil is vital to the overall quality of the circuit board. The production of high-quality copper foil is closely related to the electrolyte purification process. At this point, activated carbon has proven to be an effective and reliable purification material. This article will examine in detail the key role of activated carbon in the purification of copper foil electrolyte.

What is Electrolytic Copper Foil Solution?

Electrolytic copper foil production is the process of creating copper foil by depositing copper ions from copper sulphate aqueous solution onto the cathode by electrodeposition. To obtain ideal electrolytic copper foil, the quality of the electrolyte is critical. The electrolyte must be clean, paying attention to the maximum content of inorganic impurities. This content is as follows: zinc <1.0 g/L, iron <1.5 g/L, antimony <0.15 g/L, lead <0.1 g/L, nickel <0.1 g/L, cadmium <0.1 g/L, chromium <0.3 g/L. The non-copper inorganic metal ions content should be within a certain range and be low if possible, the lower the non-sulfate anion content, the better.

The Importance of Activated Carbon

In the production of copper foil solution, activated carbon produced from special coconut shell can effectively deal with impurities in it. This activated carbon has undergone a special activation process and has excellent adsorption performance thanks to its high surface area and rich microporous structure. These properties allow it to remove organic matter, heavy metal ions, and other contaminants in solution effectively. At the same time, its high chemical stability provides stable treatment in complex solution environments.

In conclusion, the Importance of Activated Carbon for Copper Foil

Activated carbon plays a critical role in purifying the copper foil electrolyte. Its strong adsorption capacity and chemical stability make it an important tool to ensure the quality of copper foil production.
