Lithium batteries, widely used in modern electronic technology, are based on lithium-ion batteries (Li-ion batteries). They are known for their high energy density, long lifespan, and energy-saving, environmentally friendly characteristics, gradually replacing other types of batteries. In the production process of lithium batteries, the electrode plate mold plays a crucial role in manufacturing the electrode plates, making it one of the core tools for lithium battery production. This article will introduce how to maintain and repair lithium battery electrode plate molds.

1. Structure of Lithium Battery Electrode Plate Molds

The main components of a lithium battery electrode plate mold include the upper and lower templates, guide posts, compression springs, sliding sleeves, etc. The materials used for the mold are high-quality steel and tungsten steel. While the mold structure is simple, it requires high precision, making it one of the key aspects of maintaining the lithium battery electrode plate mold.

2. Maintenance and Repair

1. Cleaning and Greasing

To ensure the mold operates efficiently and conveniently, it should be cleaned and greased after each use. Before removing the mold, use a cotton cloth or soft brush to clean the surface of the mold to remove dust and other impurities. Then, apply a thin layer of machine oil or a specialized rust prevention oil for molds to the surface of the mold. This helps prevent rusting and extends the mold's lifespan for the next use.

2. Regular Inspection of the Electrode Plate Mold

During production, the electrode plate mold may suffer damage or wear, so it needs to be inspected regularly. Key areas to check include:

• Whether the guide posts are damaged.
• The ejection gap and surface wear.
• Whether cleaning has been performed properly.

If any damage is found in the guide posts, they should be replaced or repaired promptly. If there is significant wear, grinding may be required. Regular inspections are an important way to prevent mold damage.

3. Proper Use

To ensure the performance and longevity of the lithium battery electrode plate mold, attention should be paid to the following during use:

• Adjusting pressure, temperature, and other conditions to ensure accurate results during the molding process.
• When setting up the mold for processing, choose the best processing method to ensure the mold can withstand the applied processing pressure.
• Avoiding collisions between the mold and hardware or workpieces to prevent mold damage.

4. Timely Troubleshooting

If damage or other issues occur during the use of the lithium battery electrode plate mold, they should be addressed promptly. Some issues may arise from improper mold use, while others may be due to poor mold quality, which leads to quick wear. If issues such as carbon buildup or deformation are observed, the mold should be repaired or replaced in time to prevent it from affecting its lifespan.

Conclusion

Maintaining lithium battery electrode plate molds can significantly improve production efficiency, reduce production costs, and create a smoother, more efficient manufacturing process. Therefore, regular maintenance and repair of the electrode plate mold should be conducted, issues should be resolved, and the mold should be replaced when necessary. Additionally, attention to safe machine operation and enhanced safety training is essential to increase production safety and efficiency.
