SEALED BATTERY AND ASSEMBLED BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240128493 titled 'SEALED BATTERY AND ASSEMBLED BATTERY
Simplified Explanation
The present disclosure describes a technique for improving the strength and reducing the electrical resistance of a connecting portion in a sealed battery that performs heterometal interjunction. The sealed battery includes an electrode body, a battery case, internal and external terminals for both positive and negative electrodes. In the connecting portion between the negative electrode internal terminal and the negative electrode external terminal, a plated layer is stacked between the upper ends of the terminals, joining them together. Additionally, a rough surface with recessed portions is formed on the upper surface of the negative electrode external terminal, allowing the plated layer to penetrate into the recessed portions, creating a connecting portion with high strength and low resistance.
- Plated layer is used to join the negative electrode internal and external terminals in a sealed battery.
- A rough surface with recessed portions on the negative electrode external terminal improves the connection strength and reduces resistance.

Original Abstract Submitted
the present disclosure provides a joining technique capable of improving strength and reducing electrical resistance of a connecting portion that performs heterometal interjunction in a sealed battery. a mode of the sealed battery disclosed herein includes an electrode body, a battery case, a positive electrode internal terminal, a positive electrode external terminal, a negative electrode internal terminal, and a negative electrode external terminal. in the sealed battery, in a connecting portion between the negative electrode internal terminal and the negative electrode external terminal, an upper end of the negative electrode internal terminal and the negative electrode external terminal are stacked with a plated layer interposed therebetween and, at the same time, the negative electrode internal terminal and the negative electrode external terminal are joined to each other via the plated layer. in addition, a rough surface having a plurality of recessed portions is formed on the upper surface of the negative electrode external terminal having been stacked with the plated layer interposed therebetween, and a part of the plated layer penetrates into the recessed portions. accordingly, a connecting portion having high strength and low resistance can be formed between the negative electrode internal terminal and the negative electrode external terminal.
