Lithium-Ion Battery Cathode Aluminum Foil 1235 / 1060 / 1070 H18

Lithium-ion battery cathode aluminum foil is an essential current collector material in battery
manufacturing. It is primarily used to carry cathode active materials and efficiently conduct the
electric current generated during electrochemical reactions to the external circuit.
For power batteries, energy storage batteries, and consumer electronics batteries, the thickness
accuracy, surface quality, electrical conductivity, mechanical strength, and processing consistency
of aluminum foil directly affect battery manufacturing efficiency and final battery performance.
We supply 1235, 1060, and 1070 aluminum foil in H18 temper for lithium-ion battery cathode current
collectors. Customized specifications can be provided according to customers’ battery chemistry,
coating process, equipment requirements, and purchasing standards.

Performance Advantages of Lithium-Ion Battery Cathode Aluminum Foil
1.Excellent Electrical Conductivity
Made from high-purity aluminum with low electrical resistivity, our foil helps reduce internal cell
resistance and improve charging and discharging efficiency.
2.Strong Mechanical Properties
The H18 full-hard temper provides high tensile strength, tear resistance, and bending resistance. It
is suitable for high-speed coating and winding processes, helping prevent strip breakage and
wrinkling.
3.Superior Surface Quality
The foil surface is clean and free of pinholes, oil contamination, and other defects. It provides
strong adhesion for cathode active material coatings, reducing powder shedding and delamination while
improving cell consistency.
4.Electrochemical Stability
The material offers good resistance to electrolyte corrosion and oxidation. It is less prone to
corrosion during charge-discharge cycling, contributing to a longer battery service life.
5.High Dimensional Accuracy
With tight thickness tolerance and consistent coil uniformity, our aluminum foil helps reduce
manufacturing defects and improve production yield.
