Lithium ion battery gravure technology

　　Advantages of gravure technology for lithium-ion batteries:

　　1. The intaglio design of lithium batteries can expand the effective area of the battery, significantly increasing its capacity. Under the same volume, its capacity far exceeds that of traditional flat battery designs.

　　2. The intaglio structure increases the number of grooves on the positive and negative electrode surfaces of the battery, allowing the electrodes to closely adhere to the separator, reducing the internal resistance of the battery, and enhancing stability and efficiency.

　　3. The intaglio structure increases the electrode surface area, enhances heat dissipation capability, effectively suppresses temperature rise during fast charging, effectively prevents thermal runaway, and ensures the safety performance of the battery.

　　4. This structural design is beneficial for the diffusion and flow of electrolytes during the charging and discharging process, greatly reducing the degree of electrode polarization and extending the cycle life of the battery.

　　Disadvantages of gravure technology for lithium-ion batteries:

　　1. The manufacturing process of gravure printing is relatively complex, requiring high production equipment and technology, resulting in increased production costs.

　　2. During long-term use, the intaglio structure may experience local damage due to stress concentration at the grooves, which can affect the overall performance and lifespan of the battery.

　　3. The design and manufacturing of gravure batteries require higher precision and quality control, otherwise consistency issues may arise, affecting the performance of the battery pack.

　　4. In terms of recycling, the complex structure of gravure batteries also brings certain difficulties and challenges to the recycling process.
