Londian Wason manufactures electrolytic copper foil, a critical component for lithium-ion batteries and printed circuit boards. The company’s primary product is LiB copper foil, which functions as the anode current collector in batteries for electric vehicles, energy storage systems, and consumer electronics. Londian Wason also produces PCB-grade copper foil used as a signal conductor in servers, computers, and communication equipment. As a leading global supplier by sales volume, the company serves major battery manufacturers including LG Energy Solution, CATL, BYD, and Samsung SDI. Londian Wason uses a processing fee model where it passes the cost of raw copper through to customers and earns a margin based on a value-added fee. These fees depend on product complexity; thinner and more technically demanding foils command higher prices. Londian Wason operates multiple manufacturing facilities in China and requires significant capital investment for machinery and utilities. The company is shifting its product mix toward high-end ultra-thin foils, typically between four and six micrometers, to meet demand for high-density batteries. Londian Wason is also expanding its manufacturing capacity in China and Malaysia to support global demand and is increasing its focus on the energy storage system market.
