摘要： A displacement-generating battery cell for driving a drug-delivery device is described. The cell may include at least one volume-changing element. The cell may include a housing formed according to a concertina-shaped design with folds in the walls thereof and may contain an internal chemical reaction system. The chemical reaction system may include an electrode. The electrode may be the volume-changing element. The arrangement of said chemical reaction system may be such that an expansion of the volume-changing element in a direction lengthens the cell and thus reduces the extent of the folds. Drug-delivery devices including the displacement-generating battery cell are also described.

摘要： A technology capable of sealing a target with higher airtightness is provided. The plug attaching device disclosed herein is for attaching, to a through hole of a target, a cylindrical plug having therein a non-through hole that has an opening in one end surface. The device includes an insertion pin, and a guide portion. The guide portion is slidable in the axial direction of the insertion pin. This device is configured such that the plug is disposed inside the through hole, the insertion pin is pushed into the non-through hole with the guide portion disposed on the periphery of the opening to attach the plug into the through hole, and after the attachment, the insertion pin is moved in an opposite direction to the non-through hole to remove the insertion pin from the non-through hole, and the guide portion is then detached from the opening.

摘要： Electrochemical stacks such as lithium-ion battery stacks and methods of assembling the same are disclosed. The stacks may include various electrochemical cells having different attributes. In one variation, the outer electrochemical cells may be different than the inner electrochemical cells. For example, the electrodes of the outer cells and inner cells may have different compositions, loading levels, and/or thicknesses. In a refinement, the separators of the outer cells and inner cells may have different thicknesses or porosities.

摘要： The herein-disclosed sealed battery includes a battery case, a terminal member (negative electrode external terminal) including an opposed surface opposed to the battery case, and an insulating member (negative side gasket) disposed between the sealing plate and the negative electrode external terminal. Then, the surface of the battery case and/or an opposed surface of the negative electrode external terminal includes a 1st rough surface area on at least a part of a portion contacting with the negative side gasket, and an arithmetic average roughness Sa of the 1st rough surface area is equal to or more than 1 μm. By doing this, it is possible to suppress a liquid leakage of an electrolyte caused by degradation of the negative side gasket.
