Abstract:
A method of manufacturing a lithium battery comprising a stack of a negative electrode, a separator, and a positive electrode, which method comprises applying negative electrode material onto a negative current collector so as to form the negative electrode, applying positive electrode material onto a positive current collector so as to form the positive electrode, and arranging a separator between the negative electrode and the positive electrode, wherein the method comprises the following steps:a) producing a pattern of boles in the negative electrode; b) producing a pattern of holes in the positive electrode; c) applying a polymeric material on the stack, so that the polymeric material penetrates the holes by which the negative electrode, the positive electrode and the separator are coupled and pressed together, and d) subjecting the polymeric material to a treatment with radiation.
