Title: Innovations of Ronald A Rojeski: A Pioneer in Energy Storage and 3D Printing
Introduction
Ronald A Rojeski is an accomplished inventor based in Campbell, CA, with a remarkable portfolio of 35 patents to his name. His innovations span the fields of energy storage and advanced printing technologies, showcasing his dedication to enhancing efficiency in these crucial areas.
Latest Patents
One of Rojeski's notable inventions is a lithium-ion battery anode that includes preloaded lithium. This energy storage device features a nano-structured cathode composed of a conductive substrate, an underframe, and an active layer. The design incorporates innovative structures such as nano-filaments and aerogel. Additionally, the active layer can include a catalyst to facilitate the dissociation of cathode active material, demonstrating a sophisticated approach to improving battery performance.
Another significant patent is for a jetted material printer equipped with pressure-assisted fluid extraction. This three-dimensional (3D) inkjet printer is engineered to construct objects by sequentially printing layers and stacking them. To enhance the printing speed, a pressure differential is used to extract the liquid vehicle from the ink, and the printed layer is moved away from the inkjet print heads before drying. This process allows for the conditioning and curing of dried printed layers, which are then assembled at a build station to create the final object.
