METHOD FOR PRODUCING POWER STORAGE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18462411 titled 'METHOD FOR PRODUCING POWER STORAGE DEVICE

Simplified Explanation

The method described in the patent application involves placing a lid assembly with a lid and terminal member integrated via a resin member to close an opening portion of a case body, and then laser-welding the opening portion of the case body and the peripheral portion of the lid over the entire circumference.

• Lid assembly includes lid and terminal member integrated via resin member
• Laser-welding of opening portion of case body and peripheral portion of lid
• Peripheral high-level region provided in proximate long-side opening portions and peripheral portions of the lid

Potential Applications

The technology described in this patent application could be applied in the manufacturing of power storage devices, such as batteries, capacitors, or other energy storage systems.

Problems Solved

This technology solves the problem of securely sealing the opening portion of a case body in a power storage device, ensuring the integrity and safety of the internal components.

Benefits

The benefits of this technology include improved sealing and structural integrity of power storage devices, which can lead to increased reliability and longevity of the devices.

Potential Commercial Applications

The technology could be utilized in the production of various power storage devices for consumer electronics, electric vehicles, renewable energy systems, and other applications where reliable energy storage is essential.

Possible Prior Art

One possible prior art in this field could be the use of traditional welding or adhesive methods to seal the opening portion of a case body in power storage devices. Laser-welding the opening portion and peripheral portion of the lid over the entire circumference may be a novel approach to achieving a secure seal.

How does this technology compare to traditional welding methods for sealing power storage devices?

This article does not provide a direct comparison between laser-welding and traditional welding methods for sealing power storage devices. Further research or testing may be needed to determine the advantages and disadvantages of each method in terms of durability, cost, and efficiency.

What are the potential challenges or limitations of implementing this technology in large-scale production of power storage devices?

The article does not address the potential challenges or limitations of implementing this technology in large-scale production. Factors such as cost, scalability, and compatibility with existing manufacturing processes could be important considerations that need to be explored further.

Original Abstract Submitted

A method for producing a power storage device includes placing a lid assembly that includes a lid and a terminal member integrated therewith via a resin member to close an opening portion of a case body with the lid, and laser-welding the opening portion of the case body and the peripheral portion of the lid over an entire circumference. In placing the lid assembly, a peripheral high-level region, in which a peripheral outer surface of the peripheral portion of the lid is located on the outer side relative to an opening end surface of the opening portion of the case body is provided in proximate long-side opening portions, close of the opening portion and proximate long-side peripheral portions of the peripheral portion.
