Abstract

A deformable and compressible active electrode dry film is manufactured from dry mixed dry active electrode material and dry binder powder. The electrode film and a current collector with a first surface may be stacked such that the first surface of the current collector is in contact with the dry film. The active electrode dry film and current collector may then be processed in a laminating device, such as a calendar. Lamination both densifies the active electrode film and bonds the film to the current collector.
