COMPOSITIONS AND METHODS FOR ELECTRODE FABRICATION

Provided are compositions and methods of malting and using free-standing electrode films for electrodes by a dry process. The process for forming an electrode includes combining a processing additive and an active electrode material or fibrillizable binder to form an electrode precursor material, where the processing additive has a surface roughness and a porosity and intermixing the electrode precursor material. The electrode precursor material may then be combined with the fibrillizable binder or the active electrode material and the fibrillizable binder or the active electrode material is intermixed with the electrode precursor material to form an electrode film material. The electrode film material includes the processing additive, the fibrillizable binder and the active electrode material. The electrode film material is then compressed into an electrode film.
