In the process of energy-saving and environmental protection, new energy vehicles, as a new low-carbon and environmentally friendly travel tool, are loved by many people. More and more people abandon fuel vehicles and choose new energy vehicles. As the core power of new energy vehicles, the quality of lithium batteries greatly affects the performance of new energy vehicles. Therefore, how to produce high-quality lithium batteries has become a difficult problem for many manufacturers.
Lithium battery pole piece (lug) cutting equipment - metal laser film cutting machine
In the production process of lithium battery, it is mainly divided into three parts: pole piece (lug) manufacturing, cell manufacturing and battery assembly. Each step directly determines the performance of lithium battery and also affects the performance of new energy vehicles. Therefore, every step of the production of lithium batteries has very high manufacturing requirements. Laser technology known for its high precision is gradually applied to the production of lithium batteries.
The lithium battery laser cutting machine perfectly avoids the wear, dust falling and burrs in the traditional cutting method, which may cause various dangerous problems such as battery overheating, short circuit and even explosion. The lithium battery laser cutting machine has the advantages of no physical wear, flexible cutting shape, edge quality control, higher accuracy and lower operating cost, which is conducive to reducing manufacturing costs, improving production efficiency Greatly shorten the die cutting cycle of new products.
Where is the lithium battery laser cutting machine mainly used?
Metal foil slitting
Metal foil slitting is to cut a roll of metal foil into thin strips along the long side. The laser cutting machine for lithium battery can cut the electrode coating at high speed and high quality.
Metal foil cutting
Metal foil cutting refers to cutting the elongated anode film and cathode film into required shapes. Depending on the battery design and whether the metal foil roll is completely coated, the light beam can be selected or adjusted to cut the coating or only the metal foil. The laser used in this link is the same as the aluminum foil slitting link.
Isolation film cutting
Similar to aluminum foil cutting, the cover film should also be cut into the required shape according to the battery design. Because the isolation film is composed of organic compounds, pulsed UV laser is the most suitable choice.
