【Abstract】 Composite copper foil, as a new type of negative current collector for lithium-ion batteries, has unique advantages in terms of material cost, lightweight, and functional diversification, and gives lithium-ion batteries more characteristics and functions. Therefore, composite copper foil has attracted widespread attention in recent years. In the other side, composite copper foil, as a new product, has immature manufacturing technology and has caused various controversies during the production process. This article conducts a detailed analysis of the preparation of composite copper foil, including intermediate support layer constituent, film surface treatment and copper plating. In the end, the further solutions of composite copper foil manufacture techniques are suggested reasonably.更多还原
