Recently, research in the lithium ion battery industry has found that the surface of an aluminum (Al) alloy foil used as a lithium ion rechargeable battery can be etched and roughened to improve the charging and discharging characteristics of the battery. After the surface roughening treatment, the adhesion between the battery case aluminum foil and the active material is higher than that of the aluminum foil without surface treatment. Therefore, aluminum foil for lithium batteries also plays an important role in the field of hybrid batteries and rechargeable batteries for electric vehicles.
The application advantages of battery aluminum foil are:
1, greatly improve the consistency of the battery pack, and greatly reduce the battery composition;
2, significantly reduce the increase in dynamic internal resistance of the battery cell;
3, improve the consistency of the battery pack;
4, extend battery life;
5, significantly reduce battery components.
