Electrodeposited (ED) Copper Foil

Electrodeposited (ED) Copper Foil

Electrodeposited (ED) copper foil is manufactured by depositing copper ions, via electrolysis, onto a rotating metallic mandrel to form a thin layer of foil. Through this process, very wide and high purity thin foils can be manufactured that are suitable for a range of applications from PCB's to Lithium ion batteries.Throughout the development of new battery technologies, battery manufacturers have often used copper foil that has been manufactured by rolling or by electro-deposition, often not knowing which product suited either their manufacturing process or their application.At Avocet Precision Metals we believe that ED copper is the future of LiB manufacture due to being able to achieve a higher elongation compared to the rolled counterpart, but most importantly as ED copper foil reduces the propensity for pinholes that is of upmost importance during manufacture of power storage devices.ED Copper Foil For Lightning Strike ProtectionIn LSP, the goal is to prevent damage to composite materials (like carbon fiber) by conducting the electrical energy of a lightning strike away from the structure.
