Abstract
Apparatuses, systems, materials, and methods for preparing polyethylene electrodes for use in energy storage and transfer via dry electrode processing is described herein. Ultra-high molecular weight polyethylene (UHMWPE) particles and filler particles are used to form a blended composition. With shear, the UHMWPE fibrillates to durably enmesh the filler particles. The blended composition with the fibrillated UHMWPE particles may, in turn, be used to form an article, such as an electrode. The blended composition may contain less than 10% by weight of the UHMWPE. The UHMWPE has a molecular weight of at least about 2,000,000 g/mol, a bulk density from about 0.04 g/mL to about 0.25 g/mL, and a melt enthalpy of at least 190 J/g. In some embodiments, the UHMWPE may be conditioned to alter the size and/or shape of the particles. The median diameter of the conditioned UHMWPE particles is from 5 microns to 300 microns.
