Product Description

Introduce

Electrolytic copper foil is an important material for the manufacturing of copper clad laminate (CCL), printed circuit boards (PCBs), and lithium-ion batteries. Electrolytic copper foil can be divided into lithium copper foil and standard copper foil according to different application fields; According to the thickness of copper foil, it can be divided into extremely thin copper foil (≤ 6 μ m) Ultra thin copper foil (6-12 μ m) Thin copper foil (12-18 μ m) Conventional copper foil (18-70 μ m) And thick copper foil (>70 μ m) ; According to different surface conditions, it can be divided into double-sided smooth copper foil, double-sided rough copper foil, single-sided rough copper foil, and very low profile copper foil (VLP copper foil)

Equipment and principle of foil making

1. Cathode roller:With the improvement of customer requirements and the development of technology, the diameter of the cathode roller has increased from 1m and 1.5m to 2.2m and 2.7m, with a width of 1400mm~1500mm. The material is now mostly pure titanium. The cathode roller has good corrosion resistance, and its surface quality directly affects the surface quality and visual effect of the raw (original) foil. Therefore, the roller surface roughness Ra
2. Anode holderIt is an insoluble anode and currently uses materials such as lead antimony alloy (or lead silver alloy) and titanium. As the use time of the former increases, the alloy corrodes more and more, resulting in an increase in pole distance, an increase in slot voltage, and an increase in power consumption; At the same time, due to uneven corrosion, it also affects the consistency of electrode distance, resulting in poor uniformity of copper foil. The latter consists of a titanium matrix and a coating. The coating is a mixture of iridium (56%) and tantalum (44%), and this anode has good corrosion resistance. Within a certain limit, the cell voltage will not increase, so the thickness uniformity of the raw foil is good, but the one-time investment is large. Even if the coating is damaged and thinned, it can be repaired by recoating
 3. Raw foil manufacturingCopper sulfate is used as the electrolyte, and its main components are Cu2+and H+. Under the action of direct current, cations move to the cathode and anions move to the anode. Cu2+is reduced to Cu by two electrons on the cathode, and crystallizes on the cathode roller to form a green foil. After the electrolysis process, the Cu2+content of the electrolyte decreases and the H2SO4 content increases. The electrolyte returns to the copper dissolution tank for adjustment, causing an increase in Cu2+and a decrease in H2SO4 content in the electrolyte. Through two processes of electrolysis and copper dissolution, the content of Cu2+and H2SO4 in the electrolyte is maintained in equilibrium.
