ABSTRACT:
Methods of forming battery electrodes are described. In one embodiment, a discrete amount of electrode material having a volume and a first shape is provided. The electrode material is deformably molded into a second shape which is different from the first shape and which defines a desired battery electrode shape. The battery electrode shape has a volume which is substantially the same as the volume of the provided amount of electrode material. In a preferred implementation, a molding cavity is provided and defines at least in part the desired battery electrode shape. The electrode material is placed into the molding cavity and pressed into the electrode shape.
