Systems and methods for producing battery parts, such as battery parts, are described herein. In one embodiment, a battery part machine is configured transform a profile of one or more acid rings on a battery part from a first cross-section to a second cross-section. The machine can include a rotatable spindle configured to receive the battery part, and a first tool and a second tool configured to engage the battery part. The orientation of the first tool and the second tool can be configured to engage the battery part at adjustable to polish, crimp, flare or otherwise transform the profile of the acid rings thereon to produce a finished battery part. An operator can input operating parameters to a machine controller to adjust the finished profile of the acid rings produced by the machine without requiring disassembly thereof.

A system for attaching a thermal battery to a flange of a power supply section of an underwater craft, such as a torpedo, comprising a fixing sleeve arranged around and fixed to the battery and provided with fixing lugs comprising holes for the passage of screws for attachment to the flange, wherein the sleeve is in an overall shape of a C, of which an intermediate part and ends of branches comprise the fixing lugs for fixing the fixing sleeve to the flange.

A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive and non-automotive applications. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween. A plurality of rods extend through the each heatsink assemblies to secure the heatsink assemblies and the cell with one another to form the battery module.

A sealed battery manufacturing method includes inserting a supply nozzle (120) into an opening (33) that is opened outwardly, the opening (33) being formed in a battery container (33); and introducing a detection gas (He) into the battery container in such a manner that injection of the detection gas from the supply nozzle (120) is started at a pressure smaller than a predetermined injection pressure, and then an injection pressure of the detection gas (He) is increased by stages until the injection pressure of the detection gas (He) reaches the predetermined injection pressure.

The invention relates to a stacking device and a method for stacking flat materials, e.g. electrodes having a separation film (1) interposed in a zigzag manner by means of a guiding device (8). The stacking device comprises a stacking table (11), a holder (4; 5) for immobilizing the stack, and grippers (6, 7) for picking the electrodes (2, 3) up and putting them down in a defined manner, said grippers having an excess pressure module (9) for the targeted shaping of a defined film pocket (17) in the separation film (1).
