Publication number: 20240079655Abstract: A bipolar solid-state battery includes N solid-state battery cells. Each of the N solid-state battery cells includes M solid-state cores each comprising a first current collector, cathode active material, a separator, anode active material, and a second current collector, where N and M are integers greater than one. The M solid-state cores are connected in parallel by connecting the first current collectors of the M solid-state cores in each of the N solid-state battery cells together and by connecting the second current collectors of the M solid-state cores in each of the N solid-state battery cells together. N?1 clad plates including a first side made of a first material and a second side made of a second material. The N?1 clad plates are arranged between adjacent ones of the N solid-state battery cells and the N solid-state battery cells are connected in series by the N?1 clad plates.Type: ApplicationFiled: October 7, 2022Publication date: March 7, 2024Inventors: Qili SU, Zhe LI, Meiyuan WU, Haijing LIU, Dave G.

Publication number: 20230293955Abstract: Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The upper portion can have a rear opening. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.Type: ApplicationFiled: May 23, 2023Publication date: September 21, 2023Inventors: Jacob T. Clarke, Cory S. Bacon, Dave Wu, Martin R. Jertson, Travis D. Milleman, Ryan M. Stokke

Patent number: 11725253Abstract: Embodiments are described herein of a bifurcated heat treatment apparatus and methods for localized heat treatment of a golf club hosel or golf club head. The heat treating method comprises a bifurcated process in which the golf club head is treated in the first heating unit via induction heating and then moved to the second heating unit for convection heating. Both steps are to localize the hosel heat treatment. The heat treatment apparatus may also include a cooling component, such as a heat sink, to ensure the body of the club head remains at the correct temperature during the second heating stage when the hosel is heated in isolation. The overall bifurcated method and apparatus of the localized heat treatment leads to a hosel or golf club head with at least two different hardness values to allow for manipulation of the material without cracking or fracturing.Type: GrantFiled: December 22, 2021Date of Patent: August 15, 2023Assignee: Karsten Manufacturing CorporationInventors: Dave Wu, Tyler Shaw, Matthew W.
