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.
