Copper foil in lithium batteries is extremely thin but has very high purity. It usually sells for $8,000 to $10,000 per ton in international markets. This demand remains stable because copper foil is essential in many industries beyond batteries, such as electronics and power cables. If you fail to recover copper foil, you lose a valuable revenue source and risk causing environmental damage through metal leaching. Recovering copper foil not only boosts profits but also builds a greener business image.
