In the realm of technological advancements, Electrodeposited (ED) copper foil has emerged as a pivotal material, particularly in the thriving Electric Vehicle (EV) battery industry. This thin, conductive sheet of copper is a critical component in the production of lithium-ion batteries, the powerhouse behind EVs. Understanding the intricacies of the ED copper foil manufacturing process sheds light on its significance and the innovative applications it enables.
The Journey of ED Copper Foil: From Electrolytic Bath to High-Performance Component
The creation of ED copper foil begins with an electrolytic process, where a thin layer of copper is deposited onto a rotating drum cathode immersed in an electrolytic bath. This process involves several key stages:
- Electrolytic Deposition: In the electrolytic bath, an electrical current is applied, causing copper ions to migrate from the anode to the cathode. As the drum rotates, a thin, uniform layer of copper is deposited on its surface.
- Foil Separation: Once the desired thickness is achieved, the ED copper foil is carefully separated from the drum cathode. The precise control of the electrolytic process ensures that the foil has a smooth surface and uniform thickness.
