Description

Technology Field

[0001] The present invention relates to an electrode tab that is selectively fixed to an active ingredient sheet. Background Technology

[0002] Generally, electrode tabs are used as electrical connection points for the input and output of current in various electrical and electronic components, such as batteries, sensors, and heating elements. These electrode tabs are typically manufactured in a form that is physically fixed to a specific area of ​​an active ingredient sheet (e.g., active material layer, heating layer, etc.) to establish an electrical connection with the sheet.

[0003] Referring to Korean Patent Publication No. 10-2017-0025861 and others, conventional electrode tab fixing methods such as thermal compression, ultrasonic welding, and adhesive bonding have been widely used. These methods have the advantage of being relatively simple processes and suitable for mass production. However, these conventional technologies have limitations in that the decision regarding electrode tab attachment must be made early in the manufacturing process, and the same fixing process must be applied to every product.

[0004] In particular, when the final specifications of a product may vary depending on customer requests or market demand, a uniform fixing method for electrode tabs hinders product design flexibility and lowers production efficiency. For instance, a problem arises where electrode tabs must be attached to all products and shipped according to conventional fixing methods, even though electrode tabs are not required for certain product lines. In such cases, unnecessary removal work is required during subsequent processes, and this can lead to unnecessary material waste and increased manufacturing costs.

[0005] Furthermore, in some applications, the decision regarding the attachment of electrode tabs must be made later during the product assembly or testing process. However, such selective attachment is difficult with conventional technology, and if electrode tabs are to be added in a subsequent process, separate bonding equipment and processes are required, increasing the complexity of the entire production line. This makes manufacturing process management difficult and increases the likelihood of delivery delays and quality issues.

[0006] Therefore, there is a persistent demand for a new type of electrode tab technology that allows for the selective attachment of electrode tabs to active ingredient sheets as needed, while reliably ensuring electrical reliability and mechanical bonding strength. This technology enables the flexible decision of whether to attach electrode tabs based on product specifications, thereby improving production efficiency and contributing to the development of products capable of meeting diverse customer demands.

[0066] The fixed insulating part (55) surrounds the fixed protective part (54) and may be provided with an insulating material. That is, the fixed insulating part (55) can facilitate the flow of current between the electrode tab contact part (2) and the active ingredient sheet (M) by minimizing the effect of the magnetism of the electrode tab magnetic part (3) on the electrode tab contact part (2).
