As the lithium‑battery industry continues to raise its standards for substrate flatness, Jiangsu Jinlun Roller’s spreader rollers are seeing expanding applications in the new‑energy sector. Rubber‑coated curved rollers, Teflon‑coated curved rollers, and adjustable mid‑to‑high‑profile spreader rollers are well suited for bi‑axial stretching, slitting, and rewinding of lithium‑battery separators, as well as for flattening and reeling copper and aluminum current‑collector foils. By leveraging lateral tension to eliminate micro‑folds in ultra‑thin substrates, these rollers help reduce defect rates and support stable, high‑speed operation of upstream material production lines for power batteries.
