Product Overview
This continuous lithium battery electrode slitting machine converts rolled, calendered positive and negative electrode sheets into accurately slit electrode rolls. It combines single-shaft center unwinding, controlled web transport, disc-knife roll slitting, upper and lower rewinding, edge-trim collection, web guiding, tension control, and dust removal in one coordinated production system. The result is stable strip formation with process-critical burr, straightness, width, and winding performance kept within the defined process range.
The equipment is intended for coated and calendered electrode materials used in lithium iron phosphate, lithium cobalt oxide, lithium manganate, ternary, nickel cobalt manganese oxide, lithium titanate, carbon, and graphite systems. It is suited to battery electrode preparation operations requiring continuous multiple-strip processing, including electrode formats used in cylindrical cell manufacturing and 4680 tabless cell production workflows where repeatable strip geometry and clean edges are essential.
Built for sustained manufacturing duty, this unit uses automatic closed-loop continuous tension control, an automatic web-guiding system, dedicated dust extraction, differential-shaft winding, and independent edge-scrap handling. These coordinated subsystems help keep the moving electrode web steady at production speed, reduce winding defects, and support consistent output during demanding electrode converting operations.
