Foil is an important component of lithium-ion batteries, which act as current collectors. Current collectors are important for electrochemical energy storage. They are responsible for 90% of electrical conductivity and the mechanical strength of electrodes in lithium-ion batteries. Nickel foam is considered to be used for energy absorption and rechargeable battery application because nickel foam is a good collector of alkaline supercapacitors. NF has porous structure with good electrical conductivity and excellent mechanical strength.
