POWER STORAGE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18461509 titled 'POWER STORAGE DEVICE
Simplified Explanation
The patent application describes a power storage device with a unique positive terminal design for improved performance and efficiency.
- The positive terminal is ultrasonically welded to the positive current collecting part of the electrode body.
- The surface-welded portion of the positive current collecting part has a rectangular shape and is rotated by 45 degrees or less from the virtual surface-welded portion.
- The distance from a reference position to the closest corner is longer than the virtual distance to the closest virtual corner.
Potential Applications
The technology described in this patent application could be applied in various power storage devices such as batteries, capacitors, and supercapacitors.
Problems Solved
This innovation solves the problem of inefficient power storage due to poor connection between the positive terminal and the electrode body in conventional devices.
Benefits
The benefits of this technology include improved performance, increased efficiency, and enhanced durability of power storage devices.
Potential Commercial Applications
The technology could be commercialized in the consumer electronics industry, electric vehicles, renewable energy systems, and grid energy storage solutions.
Possible Prior Art
One possible prior art could be the traditional methods of connecting terminals to electrode bodies in power storage devices, which may not provide optimal performance and efficiency.
Unanswered Questions
How does the ultrasonic welding process work in this specific application?
The patent application mentions ultrasonic welding as a key process, but it does not provide detailed information on how this process is specifically utilized in this context.
What materials are used in the construction of the electrode body and the positive terminal?
The patent application does not specify the materials used in the construction of the electrode body and the positive terminal, which could be crucial information for understanding the performance and durability of the device.
Original Abstract Submitted
A power storage device includes a flat wound electrode body, a case, and a positive terminal ultrasonically welded to a positive current collecting part of the electrode body. A surface-welded portion of a welded portion formed on a laminated current collecting part of the positive current collecting part has an outer periphery of a rectangular shape and corresponds to a virtual surface-welded portion configured such that the virtual surface-welded portion is rotated by 45 degrees or less in a rotation direction in which a closest virtual corner is moved away from an electrode body main part. A distance from a reference position to a closest corner is longer than a virtual distance from the reference position to the closest virtual corner.
