Recently, in the production line of JXJT Copper Foil Technology Corporation, the first roll of 4-micron ultra-thin lithium battery copper foil was successfully rolled off the production line. This marks that JXJT has successfully mastered the key technology of industrialized manufacturing of 4-micron ultra-thin lithium battery copper foil, and has become one of the few copper foil manufacturers in China that can mass-produce 4-micron ultra-thin lithium battery copper foil products.
Lithium battery copper foil is a key material for energy storage systems and power batteries in the new energy field, and its thickness directly affects the overall performance of the cells. At present, according to the needs of improving battery performance and reducing costs, the demand for lithium battery copper foil in the power battery market has transitioned from 8 microns to 6 microns. Therefore, leading companies have begun to switch 4.5-micron products in small quantities, and 4-micron products are in the testing stage.
JXJT's lithium battery R&D team locks in high-end needs, constantly transforms the needs of high-end high-quality customers into technology and quality control standards, and ultimately relies on product and technology reform and innovation.
The production requirements of the ultra-thin lithium battery copper foil manufacturing process are very strict. "It's like the cling film roll is not good, and it is prone to tearing, wrinkling, and breaking. These are the key factors that plague the production process of lithium battery copper foil from 4.5 microns to 4 microns.
