DEVICE FOR AND METHOD OF DETERMINING WHETHER OR NOT ELECTRODE TAB IS BENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17730766 titled 'DEVICE FOR AND METHOD OF DETERMINING WHETHER OR NOT ELECTRODE TAB IS BENT

Simplified Explanation

The patent application describes a device for determining whether or not electrode tabs in an electrode assembly are bent. The device includes a stable nesting portion where the electrode assembly is placed, an electrode tab contact portion that moves downward to bend the electrode tab and then elastically restores it to its original state, a weight measurement unit that measures the weight of the elastically restored electrode tab on a per-area basis, and a determination unit that determines if the electrode tab is bent based on the measured weight in different areas.

  • The device is designed to detect bent electrode tabs in an electrode assembly.
  • It includes a stable nesting portion for holding the electrode assembly securely.
  • An electrode tab contact portion is used to bend the electrode tab and then restore it to its original state.
  • A weight measurement unit measures the weight of the elastically restored electrode tab in different areas.
  • The determination unit analyzes the measured weight to determine if the electrode tab is bent.

Potential Applications

  • This device can be used in the manufacturing process of batteries to ensure the quality of electrode assemblies.
  • It can also be utilized in research and development of new battery technologies to evaluate the bending characteristics of electrode tabs.

Problems Solved

  • The device solves the problem of detecting bent electrode tabs in an electrode assembly, which can affect the performance and reliability of batteries.
  • It provides a reliable and efficient method for identifying bent electrode tabs during the manufacturing process, reducing the risk of faulty batteries reaching the market.

Benefits

  • The device allows for quick and accurate detection of bent electrode tabs, improving the overall quality control of battery production.
  • By identifying bent electrode tabs early on, manufacturers can take corrective measures to prevent further issues and ensure the reliability of the batteries.
  • The weight measurement approach provides a non-destructive and non-contact method for assessing the bending status of electrode tabs, minimizing potential damage to the electrode assembly.


Original Abstract Submitted

A device for detemining whether or not positive and negative electrode tabs constituting an electrode assembly are bent includes: a stably nesting portion in which the electrode assembly is stably nested; an electrode tab contact portion arranged on a side surface of the stably nesting portion and configured to move downward so as to come into contact with one end portion of an electrode tab, bending the electrode tab, and to elastically restore the electrode tab to an original state thereof; a weight measurement unit arranged above the stably nesting portion and configured to measure, on a per-area basis, a weight of the electrode tab that is elastically restored to an original state thereof; and a determination unit configured to determine whether or not the electrode tab is bent, depending on an area where the weight is measured.
