ELECTRODE QUALITY EVALUATION METHOD AND ELECTRODE MANUFACTURING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17916932 titled 'ELECTRODE QUALITY EVALUATION METHOD AND ELECTRODE MANUFACTURING METHOD
Simplified Explanation
The patent application describes a method for evaluating the quality of electrodes used in various applications. The method involves measuring the color coordinate value of the active material layer on the electrode before roll-pressing. Based on the measured value, the electrode is evaluated as either good or defective.
- The method evaluates electrode quality by measuring the color coordinate value of the active material layer.
- The electrode consists of a current collector and an active material layer.
- The measurement is done using an optical instrument.
- If the measured color coordinate value satisfies a predetermined criterion, the electrode is considered good.
- If the measured color coordinate value does not satisfy the predetermined criterion, the electrode is considered defective.
Potential Applications
- Battery manufacturing: This method can be used to quickly identify defective electrodes before they are used in battery production, ensuring the quality of the final product.
- Electronics industry: The method can be applied to evaluate the quality of electrodes used in electronic devices, such as capacitors or sensors.
Problems Solved
- Efficient quality control: The method provides a simple and quick way to filter out defective electrodes, reducing the time and effort required for quality control.
- Early detection of defects: By evaluating the electrodes before roll-pressing, potential defects can be identified early in the manufacturing process, preventing further waste of resources.
Benefits
- Time-saving: The method allows for a rapid evaluation of electrode quality, enabling manufacturers to quickly identify and remove defective electrodes from the production line.
- Cost-effective: By filtering out defective electrodes early on, manufacturers can avoid wasting resources on further processing and assembly of faulty components.
- Improved product quality: Ensuring that only high-quality electrodes are used in the manufacturing process leads to better overall product quality and reliability.
Original Abstract Submitted
Provided is a method of evaluating electrode quality capable of simply and quickly filtering out defective electrodes by measuring a color coordinate value of electrodes before roll-pressing, which specifically includes: providing an electrode which includes a current collector and an active material layer formed on the current collector and has not been roll-pressed; measuring a color coordinate value of the active material layer using an optical instrument; and evaluating the electrode as a good product when the measured color coordinate value satisfies a predetermined electrode quality evaluation criterion and as defective when the measured color coordinate value does not satisfy the predetermined electrode quality evaluation criterion.
