METHOD OF MANUFACTURING POWER STORAGE CELL AND POWER STORAGE CELL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18482412 titled 'METHOD OF MANUFACTURING POWER STORAGE CELL AND POWER STORAGE CELL

Simplified Explanation

The abstract describes a method of manufacturing a power storage cell involving preparing a case main body, a lid main body with a pressure release valve, and an inversion plate, welding the inversion plate to the lid main body, and connecting the lid main body to the case main body.

• The lid main body includes a pressure release valve.
• The welding process starts from the opposite portion of the inversion plate, away from the pressure release valve, and ends at that opposite portion after welding the periphery of the inversion plate to the lid main body.

Potential Applications

The technology described in this patent application could be applied in the manufacturing of power storage cells for various industries such as automotive, renewable energy, and consumer electronics.

Problems Solved

This technology solves the problem of efficiently manufacturing power storage cells with a pressure release valve for safety and performance reasons.

Benefits

The benefits of this technology include improved safety, better performance, and potentially lower manufacturing costs for power storage cells.

Potential Commercial Applications

A potential commercial application of this technology could be in the production of electric vehicle batteries, solar energy storage systems, and portable electronic device batteries.

Possible Prior Art

One possible prior art could be the traditional methods of manufacturing power storage cells without the specific welding process described in this patent application.

How does this technology compare to existing methods of manufacturing power storage cells?

This article does not provide a direct comparison between this technology and existing methods of manufacturing power storage cells. Further research or a comparative analysis would be needed to answer this question.

What are the specific safety benefits of incorporating a pressure release valve in the lid main body of a power storage cell?

The article mentions the inclusion of a pressure release valve in the lid main body, but it does not elaborate on the specific safety benefits of this feature. Additional information or testing results would be necessary to answer this question accurately.

Original Abstract Submitted

A method of manufacturing a power storage cell includes: preparing a case main body, a lid main body, and an inversion plate; welding the inversion plate to the lid main body; and connecting the lid main body to an opening of the case main body. The lid main body prepared in the preparing includes a pressure release valve. In the welding, the welding of the inversion plate to the lid main body is started from an opposite portion of the inversion plate that is located opposite to a side of the inversion plate facing the pressure release valve, and after welding a periphery of the inversion plate, the welding of the inversion plate to the lid main body is ended at the opposite portion.
