Lithium batteries are widely used in new energy vehicles, consumer electronics, energy storage equipment, and other fields, and their safety and stability are crucial. The manufacturing process of lithium batteries involves multiple high-temperature links, such as cell drying, tab welding, and module packaging, and requires auxiliary materials to have excellent high-temperature resistance, insulation, and flame retardancy. LVZHIMEI high-temperature tape, with its customized product series for lithium battery manufacturing, provides comprehensive safety and stability guarantees for the production of lithium batteries.
In the cell winding process of lithium batteries, LVZHIMEI high-temperature tape is used for fixing and insulation. The lithium battery cell is composed of positive electrode, negative electrode, separator, and electrolyte. During the winding process, the electrode sheet and separator need to be firmly fixed to avoid displacement and deformation. LVZHIMEI high-temperature tape for cell winding has good flexibility and adhesion, can closely fit the surface of the electrode sheet and separator, and maintain stable adhesion during the subsequent drying process (temperature up to 120℃-150℃). At the same time, the tape has excellent electrical insulation performance, which can effectively isolate the positive and negative electrodes, prevent short circuits, and ensure the safety of the cell.
In the tab welding and fixing process, LVZHIMEI high-temperature tape plays a key role in protection and insulation. The tab is the key part connecting the cell and the external circuit, and its welding quality directly affects the performance of the lithium battery. During the tab welding process, the temperature of the welding point can reach 200℃-250℃, and the tape is used to protect the tab root and the cell surface, preventing damage caused by high temperature and welding spatter. After welding, the tape is used to fix the tab, ensuring that the tab is firmly connected and not easy to break or loosen due to vibration and extrusion. The tape has good high-temperature resistance and aging resistance, can maintain stable performance during the service life of the lithium battery, and avoid safety hazards caused by tape failure.
In the cell drying and module packaging processes, LVZHIMEI high-temperature tape also shows excellent performance. The cell drying process is to remove the moisture in the cell, which needs to be carried out in a high-temperature and vacuum environment. The tape used in this process must have good high-temperature resistance and low outgassing rate, so as not to release harmful gases and contaminate the cell. LVZHIMEI high-temperature tape has been specially treated to have a low outgassing rate, which meets the requirements of cell drying processes. In the module packaging process, the tape is used for bonding and fixing the cells, and at the same time, it plays a role in insulation and flame retardancy. The flame-retardant high-temperature tape launched by LVZHIMEI can effectively prevent the spread of fire in case of abnormal thermal runaway of the lithium battery, improving the safety of the battery module.
LVZHIMEI has carried out in-depth research and development according to the special needs of lithium battery manufacturing, and its high-temperature tape products comply with the safety standards of the lithium battery industry, non-toxic, environmentally friendly, and flame-retardant. With the rapid development of the new energy industry, LVZHIMEI high-temperature tape will continue to upgrade its performance, providing more reliable safety guarantees for the high-quality development of the lithium battery industry.
