摘要： A battery configured to support a relatively high rate of energy discharge relative to its capacity for energy intensive therapy delivery. The battery includes a feedthrough insulator cap disposed within the interior of the battery on at least a portion of a ferrule, at least a portion of an insulator, and at least a portion of a pin, which define a feedthrough extending through an enclosure of the battery; a first electrode disposed within the enclosure and electrically coupled to the pin; a second electrode disposed within the enclosure and separated a distance from the first electrode; and an electrolyte disposed between the first electrode and the second electrode. During operation of the battery, the feedthrough insulator cap reduces dendrite formation on at least a portion of the ferrule, the pin, or both.

摘要： A method for manufacturing a secondary battery includes: an accommodating process of accommodating an electrode assembly in a battery case so that an electrode lead connected to the electrode assembly protrudes to both sides of the outside of the battery case; a sealing process of sealing an outer circumferential surface of the battery case after the accommodating process; a coupling process of coupling a coupling clip to the electrode lead after the sealing process; and a transfer process of transferring the cell to a position for a next process after a gripper grips the coupling clip after the coupling process.

摘要： A battery, including a battery cell and a housing assembly accommodating the battery cell. The battery cell includes a first tab. The housing assembly includes a first housing body and a second housing body. The first housing body and the second housing body define an accommodation space to accommodate the battery cell. The first housing body and/or the second housing body include an installation portion provided with a via hole. A conductive member is disposed on an inner surface or an outer surface of the housing assembly and electrically connected to the first tab. In a through direction of the via hole, a projection of the conductive member is at least partially located in the via hole. The conductive member can avoid occupying internal space of the housing assembly, and increase the energy density of the battery. An electric device containing the battery is provided.
