Abstract
Materials and methods for preparing electrode film mixtures and electrode films including reduced damage bulk active materials are provided. In a first aspect, a method for preparing an electrode film mixture for an energy storage device is provided, comprising providing an initial binder mixture comprising a first binder and a first active material, processing the initial binder mixture under high shear to form a secondary binder mixture, and nondestructively mixing the secondary binder mixture with a second portion of active materials to form an electrode film mixture.
Claims20
A parallel processing method for preparing an electrode film comprising:
- providing an initial binder mixture comprising a first binder and a first active material;
- processing the initial binder mixture under high shear to form a secondary binder mixture;
- forming an electrode film mixture by mixing the secondary binder mixture with a second active material by a first nondestructive mixing process;
- and
- forming an electrode film from the electrode film mixture, wherein the electrode film is a free-standing film.
