Description
In the field of current collector for batteries, functional coating is proven to be a breakthrough technology Surface coating of Al foil with one or more conductive materials exhibits two-dimensional or multidimensional conductive networks. According to theoretical simulation and experimental results, the coating technology is optimized. Compared to state-of-the-art modified aluminum foil, the functional coating prepared by our technology has thinner thickness, lower resistance and enhanced adhesion. Consequently, the electrochemical performance could be improved effectively with the modified AL foil. Moreover, the cost of production and use can reduced.
