Abstract:
According to one embodiment, in a manufacturing method of a sealed secondary battery of the embodiment, a first sealing body, which is configured to seal an opening portion of a lid body to cover the opening portion and is formed into a sheet-like shape by using a metal material, is placed on the lid body, and the first sealing body is welded to the lid body. The sealed secondary battery having the first sealing body welded thereto is charged, and the sealed secondary battery is discharged after the charge. A hole is bored in the first sealing body to form a hole portion after the discharge, a second sealing body is placed to cover the first sealing body, and the second sealing body is welded to the lid body through the first sealing body.
Abstract:
The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a first set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The separator may include a ceramic coating and a binder coating over the ceramic coating. During manufacturing of the battery cell, the layers are stacked, and the binder coating is used to laminate the first set of layers within the first sub-cell by applying at least one of pressure and temperature to the first set of layers. One or more fiducials are also disposed on each electrode from a set of electrodes for the battery cell and/or a fixture for the electrodes. The one or more fiducials may be used to align the electrodes during stacking of the set of electrodes.

Abstract:
Disclosed is a pole sheet laser cutting machine. It comprises a base frame component, a laser cutting device, a cutting manipulator component for driving the laser cutting device, a control system, and at least one sheet feeding assembly; the sheet feeding assembly comprises a material grabbing manipulator component, a fixed length feeding component and a material releasing component, with both the cutting manipulator component and the material grabbing manipulator component being mounted on the base frame component, the fixed length feeding component being arranged between the material grabbing manipulator component and the material releasing component, and the control system being connected to the cutting manipulator component, the material grabbing manipulator component and the fixed length feeding component. The present invention achieves the sheet making process for lithium ion batteries or super capacitors by applying laser technology, which is able to overcome the problems that existed in the prior art through applying a traditional cutting process so that the pole sheets were easily deformed and the burrs were relatively large, etc., and at the same time, the quality of the sheet making process and hence the rate of acceptable products are improved through the control of the control system.
