Latest Patents

Mille’s listed patent work includes two inventions titled “Battery Cell Having Welded Battery Cap.”

One patent describes a method for constructing a battery cell. The process involves forming a can and a jelly roll, placing the jelly roll and a top insulator inside the can, assembling the battery cap, connecting the cathode to a conductive rupture plate, and welding the cap to the can’s inner surface. The cap assembly includes an outer conductive ring, an insulator ring, a conductive top plate, and a conductive rupture plate.

The other patent describes a battery-cell structure with a cap welded to the can above the top insulator. The outer conductive ring, insulator ring, and conductive top plate are crimped together. A conductive rupture plate connects electrically to the top plate, while the cathode connects to the rupture plate and extends into the jelly roll. The design may also include an opening in the top plate covered by a welded central portion of the rupture plate.

Career Highlights

Mille’s listed inventions focus on battery-cell construction and the integration of conductive and insulating components. The welded cap design brings together cell sealing, electrical connections, and a rupture plate within a compact assembly.
