METHOD FOR PRODUCING POWER STORAGE DEVICE AND POWER STORAGE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18462408 titled 'METHOD FOR PRODUCING POWER STORAGE DEVICE AND POWER STORAGE DEVICE
Simplified Explanation
The method described in the patent application involves forming a lid assembly for a power storage device by forging a protruding portion between a peripheral portion and an insertion-hole surrounding portion of the lid. This protruding portion is designed to block scattered light of a laser beam from reaching a resin member, with specific dimensions to ensure effectiveness.
- Forging process used to create a protruding portion on the lid assembly
- Protruding portion blocks scattered light of a laser beam from reaching resin member
- Specific distance measurements ensure optimal performance of the protruding portion
Potential Applications
The technology described in this patent application could be applied in the manufacturing of power storage devices, such as batteries or capacitors, where precise laser welding is required to seal the components.
Problems Solved
This technology solves the problem of scattered light from a laser beam interfering with the welding process of a power storage device, which could lead to defects or malfunctions in the final product.
Benefits
The benefits of this technology include improved welding quality, reduced risk of defects, and enhanced overall performance and reliability of power storage devices.
Potential Commercial Applications
The technology could be utilized by manufacturers of batteries, capacitors, or other power storage devices to improve the efficiency and reliability of their products.
Possible Prior Art
One possible prior art could be the use of shielding or masking techniques to prevent scattered light from interfering with laser welding processes in manufacturing.
Unanswered Questions
How does the protruding portion affect the overall structural integrity of the lid assembly?
The protruding portion may add strength to the lid assembly, but further testing or analysis would be needed to confirm this.
Are there any potential drawbacks or limitations to using this forging method for creating the lid assembly?
It is possible that the forging process could introduce imperfections or weaknesses in the lid assembly, so thorough quality control measures would be necessary to address this concern.
Original Abstract Submitted
A method for producing a power storage device includes forming a lid, forming a lid assembly, closing, and welding. In forming a lid, there is included forming, by forging, a protruding portion between a peripheral portion and an insertion-hole surrounding portion of the lid to block scattered light of a laser beam from being irradiated to a resin member, with a distance D from an end surface of the peripheral portion to a side surface of the protruding portion falling within 0.5t (D≤0.5t) relative to a thickness t of the lid.
