1. A method of manufacturing an electrode product, the method comprising:
- providing a current collector comprising a first surface;
dry mixing dry particles of active electrode material and dry binder to form a dry powder;
providing a dry film of the dry mixed dry active electrode material and dry binder powder;
stacking the dry film and the current collector so that the first surface is in contact with the dry film;
and laminating the current collector and the dry film by pressing the current collector and the dry film to cause the dry film to densify and to adhere to the first surface, thereby obtaining a laminated electrode product;
wherein the step of laminating is performed so that the dry film is densified without spreading to an extent necessitating trimming of the dry film after laminating.

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.
