TECHNICAL FIELD

[0002] Electrolytic copper foil is an important material for lithium ion batteries and printed circuit board manufacturing, often requiring cutting, copper dissolution, electrolysis and other processes of copper plate. In the electrolysis process, electrolyte is an essential material. By adding electrolyte in the electrolysis tank, the anode and cathode are powered to undergo electrolysis reaction, thereby generating electrolytic copper foil. Electrolyte is a consumable (electrolyte in electrolytic copper foil production has the characteristics of consumables, with continuous consumption of metal ions: copper ions (such as copper sulfate) in the electrolyte are continuously deposited to form copper foil during electrodeposition, and copper salt (such as CuSO4) needs to be replenished regularly to maintain the concentration). In particular, in the production process of electrolytic copper foil, the concentration of copper ions (Cu²⁺) in the electrolyte decreases over time, the acidity is unbalanced due to the consumption of sulfuric acid (H2SO4), impurities accumulate due to the decomposition of additives, affecting the electrodeposition efficiency and copper foil quality (such as rough surface, uneven thickness), and the enrichment of impurity metal ions (such as Fe²⁺, Zn²⁺) will interfere with the crystallization process. Therefore, the electrolyte needs to be replaced or supplemented to maintain the stability of the composition and ensure the mechanical properties and consistency of the copper foil.
