摘要： In some examples, a method for forming an energy storage device assembly, e.g., for an implantable medical device, may comprise partially enclosing electrodes of an energy storage device within a foil pack, wherein the foil pack includes an unsealed portion and a sealed portion when partially enclosing the electrodes of the energy storage device. The method may further comprise forming a first heat seal at the unsealed portion of the foil pack, and subsequently forming a second heat seal that is redundant with the first heat seal of the foil pack.

摘要： A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.
