Lithium battery positive aluminum foil
Why do lithium-ion batteries use aluminum foil as the positive electrode of the battery instead of copper foil? Both copper foil and aluminum foil can be used as current collectors. Lithium battery positive aluminum foil, due to the active chemical nature of aluminum, aluminum foil will be consumed first when the battery is discharged. , This will damage the battery and reduce the battery's service life. And if the aluminum foil is used as the positive electrode of the battery, it can protect the lithium electronic battery.
Aluminum foil has thermal conductivity, electrical conductivity and certain mechanical strength. has 10 foil rolling mills with an annual output of more than 50,000 tons of aluminum foil. Lithium battery positive aluminum foil is produced through an online plate roller and a Siemens control system. The imported high-precision rolling mill has a uniform, clean surface, flat plate shape, and no obvious roll marks, pitting, voids, or corrosion marks. It has won unanimous praise from major manufacturers in the lithium-ion battery manufacturing industry.
