CICC believes that the composite copper foil conforms to the development trend of the industry and is a potential new type of negative collector material for lithium battery. Composite copper foil has three advantages: low cost, safer and high energy density. Low cost: composite copper foil is less sensitive to copper price, and the cost of raw materials accounts for about 40% - 50%, which is significantly lower than 78% of traditional electrolytic copper foil; Safer: the composite copper foil has the structure of "insulating substrate + thin conductive layer", which can effectively prevent the battery from losing control of heat in case of short circuit in the battery. High energy density: the density of polymer organic materials is lower, which can greatly reduce the weight of composite collector and improve the weight and energy density of battery.
