Title: Innovations by James I Stevens
Introduction
James I Stevens is an accomplished inventor based in Irmo, SC (US). He has made significant contributions to the field of electrolytic capacitors, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of capacitor foils.
Latest Patents
James I Stevens' latest patents include innovations in capacitor foil technology. One of his notable inventions is a "Capacitor foil with enhanced surface area." This invention provides an improved electrolytic capacitor by producing an anode foil with areas that are not subject to stress during manufacturing being highly etched. In contrast, areas that are subject to stress are lightly etched or not etched at all. The process includes an etch mask that protects portions of the anode foil during the etching process, which enhances the overall performance of the capacitor. The highly etched areas, which are brittle, contribute to increased capacitance and improved energy density. For layered or stacked capacitors, a weld tab is covered with the etch mask to facilitate the connection of the anode layers. Additionally, the method allows for strong edges to be maintained, reducing the risk of cracking during stamping and assembly operations.
Another patent by Stevens is the "Process for making a capacitor foil with enhanced surface area," which shares similar principles and benefits as the first. This innovative approach allows for high gain foil to be used in flat areas while masking strengthens locations where sharp bends occur, thereby improving capacitance.
