Latest Patents

Ryuta Yamamoto holds a patent for "Ultra-high molecular weight polyethylene (UHMWPE) particles and filled articles produced therewith." This patent describes apparatuses, systems, materials, and methods for preparing polyethylene electrodes for use in energy storage and transfer via dry electrode processing. The invention utilizes UHMWPE particles and filler particles to create a blended composition. Through shear processing, the UHMWPE fibrillates to durably enmesh the filler particles. The resulting blended composition can be used to form articles such as electrodes, with the UHMWPE content being less than 10% by weight. The UHMWPE has a molecular weight of at least about 2,000,000 g/mol, a bulk density ranging from about 0.04 g/mL to about 0.25 g/mL, and a melt enthalpy of at least 190 J/g. Additionally, the UHMWPE may be conditioned to alter the size and/or shape of the particles, with a median diameter ranging from 5 microns to 300 microns.
