SEALED BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18544761 titled 'SEALED BATTERY

Simplified Explanation

The technique disclosed in this patent application involves suppressing movement of an electrode body inside an exterior body by using a sealed battery with specific design features.

• The sealed battery includes an electrode body with a wide rectangular face, an exterior body made of laminated film, and positive and negative electrode current collector terminals.
• The exterior body has a housing part to contain the electrode body and a sealed part to isolate the inside and outside of the exterior body.
• The housing part has a flat face facing the wide face of the electrode body and four side walls that rise from the sealed part towards the flat face.
• Two of the side walls corresponding to the long sides of the wide face curve towards the electrode body and inward of the exterior body to closely approach the electrode body.

Potential Applications

This technology could be applied in various electronic devices requiring stable and secure battery components, such as smartphones, laptops, and electric vehicles.

Problems Solved

This innovation solves the problem of electrode body movement within a battery, which can lead to short circuits, reduced performance, and safety hazards.

Potential Commercial Applications

The technology could be valuable for battery manufacturers looking to enhance the quality and safety of their products, as well as for electronic device manufacturers seeking reliable battery solutions.

Possible Prior Art

One possible prior art could be the use of various methods to secure electrode bodies within batteries, such as adhesives, mechanical fasteners, or additional casing layers.

How does this technology compare to existing methods of securing electrode bodies in batteries?

This article does not provide a direct comparison to existing methods of securing electrode bodies in batteries.

What specific materials are used in the laminated film of the exterior body?

The patent abstract does not specify the materials used in the laminated film of the exterior body.

Original Abstract Submitted

Provided is a technique capable of suppressing movement of an electrode body inside an exterior body. According to the technique disclosed herein, a sealed battery is provided, which includes an electrode body having a wide face having a rectangular shape, an exterior body made of a laminated film, and positive electrode and negative electrode current collector terminals. The exterior body includes a housing part housing the electrode body, and a sealed part formed around the housing part to isolate the inside and the outside of the exterior body from each other. The housing part has a flat face facing the wide face of the electrode body and four side walls corresponding to four sides of the wide face respectively, the four side walls being formed so as to rise from the sealed part toward the flat face. A pair of the side walls corresponding to long sides of the wide face curves toward the electrode body and inward of the exterior body so as to closely approach the electrode body.
