Publication number: 20240128027Abstract: A capacitor manufacturing method described herein includes a process for the isolation of edges of electrode foils in an electrolytic capacitor after slitting the electrode foils from a mother foil. For example, a coating process may be incorporated into the capacitor manufacturing so that the edges of the electrode foils may undergo isolation with a deposition of a layer of epoxy or resin. A manufacturing machine that incorporates a resin coating process may be positioned in the manufacturing line, such that the edges of the slit electrode foils undergo a deposition of a coating of an electrical isolator, such as a polymer, an epoxy, a resin, a ceramic, and/or an oxide layer. As another example, a combined foil with interleaving conducting bands and isolating strips may also be used to form the electrode foils with isolated edges.Type: ApplicationFiled: November 8, 2023Publication date: April 18, 2024Inventors: Joel Lang, Ronit Romm

Publication number: 20230386758Abstract: Electrolytic capacitors may use a canister and a lid to confine an electrolyte and prevent the electrolyte from evaporating during use, and an improved seal between the canister and the lid may be achieved by increasing the surface area of the seal. For example, the surface area of the seal may be increased by changing the shape and/or thickness of the canister edge. For example, the surface area of the seal may be increased by changing the shape of an elastomer layer of the lid and/or adding an annular protuberance at the circumference of the lid. For example, the surface area of the seal may be changed by changing the process for forming the edge during the capacitor sealing.Type: ApplicationFiled: August 8, 2023Publication date: November 30, 2023Inventors: Joel Lang, Ronit Romm, Bryon Roos Gomberg

Patent number: 11641041Abstract: Powders, electrodes, zinc-air batteries and corresponding methods are provided. Powders comprise perforated shells having a size of at least 100 nm and comprising openings smaller than 10 nm. The shells are electrically conductive and/or comprise an electrically conductive coating. Powders further comprise zinc and/or zinc oxide which resides at least partially within the shells. Methods comprise wetting the shells with a zinc solution to yield at least partial penetration of the zinc solution through the openings, and coating zinc internally in the shells by application of electric current to the shells. Upon electrode preparation from the powder, cell construction and cell operation, zinc is oxidized to provide energy and the shells retain formed Zn O therewith, providing sufficient volume for the associated expansion and maintaining thereby the mechanical stability and structure of the electrode—to enable many operation cycles of the rechargeable zinc-air batteries.Type: GrantFiled: November 21, 2018Date of Patent: May 2, 2023Assignee: PHINERGY LTDInventors: Dekel Tzidon, Joel Lang

Publication number: 20220209303Abstract: Disclosed herein are manufacturing methods, devices, and systems for winding electrodes and separators to form stacked cells. Winding of stacked cells may comprise printing markers, such as fiducial markers, on an electrode foil. Active materials may be printed on the electrodes aligned with the fiducial markers, and the active materials may be dried or baked. Several electrodes may be processed together on one foil to create several cells. One or more anode electrodes and cathode electrodes may be wound around a mandrel with separators between them. The one or more wound-stacked cells may be removed from the mandrel and may be further processed to create secondary cells.Type: ApplicationFiled: December 29, 2021Publication date: June 30, 2022Inventors: Joel Lang, Sofia Curland

Patent number: 11230835Abstract: A storm water management system includes a flow control device that includes a float in a storage chamber responsive to changes in water level and a valve disposed between the storage chamber and a discharge. The valve includes a relatively movable valving member connected to the float and a fixed valving member. Each valving member has a through opening that receives storm water flowing between the storage chamber and the discharge. The through-openings overlap one another whereby relative displacement of the valving members caused by float movement defines a variable-sized orifice between the storage chamber and the discharge that regulates the discharge rate of storm water from the system. The shapes of the overlapping openings enable the valve to closely follow the ideal output hydrograph and maximize the discharge rate as a function of storm intensity, thereby minimizing the required volume of the storage chamber.Type: GrantFiled: August 2, 2018Date of Patent: January 25, 2022Assignee: Lane Enterprises, Inc.Inventors: Timothy Joel Lang, Kevin Marshall Miller
