  • Patent number: 11329348
    Abstract: A cylindrical battery cell includes an electrode assembly of a cathode/separator/anode structure and an electrolyte disposed in a battery case, a cylindrical metal container forms the battery case with the electrode assembly and the electrolyte disposed therein, a cap assembly is mounted on the open upper end of the metal container and a gasket of an elastic material is interposed between the metal container and the cap assembly. The upper end of the metal container is clamped and bent inward toward the central axis of the battery cell to enable the upper portion of the metal container to surround the exterior surface of the gasket. A recessed groove configured to partially receive the gasket by clamping, is formed on the interior surface of the inward-bent portion of the metal container. Accordingly, damage to the gasket interposed between the metal container and the cap assembly is reduced and inhibits electrolyte leakage.

  • Patent number: 11316154
    Abstract: A three dimensional (3D) In-Silicon energy storage device is provided by a method that includes forming a thick dielectric material layer on a surface of a silicon based substrate. A 3D trench is then formed into the dielectric material layer and the silicon based substrate, and thereafter a dielectric material spacer is formed, in addition to the dielectric remaining on the field of the substrate, as well as along a sidewall of the 3D trench, and on a first portion of a sub-surface of the silicon based substrate that is present at a bottom of the 3D trench. A second portion of the sub-surface of the silicon based substrate that is present in the 3D trench remains physically exposed. Active energy storage device materials can then be formed laterally adjacent to the dielectric material spacer that is within the 3D trench and on the dielectric material layer.
