A. introduction
During the cutting and punching process of lithium battery electrodes, burrs are prone to occur. This article briefly explains the causes, hazards, and solutions of burrs.
B.The impact of burrs on lithium batteries
1. Impact on battery performance: Burrs may cause poor contact between the electrodes, affect battery charging and discharging efficiency, and reduce battery capacity.
2. Increase safety hazards: Burrs may pierce the battery separator, causing short circuits and even leading to safety accidents such as thermal runaway and fire of the battery.
3. Reduce product quality: Burrs can increase the internal resistance of the battery, reduce its cycle life, and affect product quality.
4. Increased production costs: Burrs may lead to scrap of the polarizer, increasing production costs.
C. Reasons for burr formation
1. Tool wear: Over prolonged use, tool wear can cause the cutting edge to become dull, resulting in burrs.
2. Equipment failure: During the operation of the equipment, faults in the transmission system, tool positioning system, etc. may cause insufficient contact between the tool and the material, resulting in burrs.
3. Improper operation: Improper use of tools and equipment by the operator, such as incorrect tool installation, excessive feed speed, etc., may also lead to the formation of burrs.
4. Material issues: The characteristics of lithium battery electrode material itself, such as tensile strength, hardness, etc., may also affect the generation of burrs.
D. Solution measures
1. Regular inspection of cutting tools: Regularly inspect and replace cutting tools to ensure their sharpness and avoid burrs caused by tool wear.
2. Equipment maintenance: Regularly maintain the equipment to ensure its normal operation and reduce the occurrence of burrs caused by equipment failures.
3. Standardized operation: Strengthen employee training, standardize operating procedures, ensure correct tool installation, moderate feed rate, and reduce burrs caused by improper operation.
4. Choose high-quality materials: When purchasing lithium battery electrode materials, choose products with reliable quality and stable performance to reduce burrs caused by material problems.
E. Attention
1. Operators should receive professional training, be familiar with the operation and maintenance methods of equipment, and ensure standardized operation.
2. When using cutting tools, it is necessary to strictly follow the instructions for using the tools to avoid burrs caused by improper use of the tools.
3. During the operation of the equipment, regular inspections and maintenance should be carried out to ensure normal operation and avoid burrs caused by equipment failures.
4. When purchasing lithium battery electrode materials, it is important to choose products with reliable quality and stable performance to avoid burrs caused by material issues.
5. In the production process, it is necessary to strengthen the inspection and management of product quality, timely detect and handle burrs, and avoid affecting product quality and safe use.
In short, understanding the causes and hazards of burrs on lithium battery electrodes and taking effective solutions can improve product quality, reduce production costs, and ensure the safe use of lithium batteries.
