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.
Main Applications
Our 1235, 1060, and 1070 H18 aluminum foil can be used in a wide range of lithium-ion battery manufacturing applications.
Power Lithium-Ion Batteries
Used as cathode current collector material for electric vehicle batteries, suitable for cylindrical, prismatic, and pouch cell production systems.
Energy Storage Batteries
Suitable for lithium-ion batteries used in energy storage systems, meeting the requirements of large-scale and continuous manufacturing.
Consumer Electronics Batteries
Applicable to lithium-ion batteries for smarts, tablets, laptops, digital devices, and other consumer electronic products.
Other Lithium-Ion Battery Applications
Depending on battery chemistry and manufacturing process requirements, the foil can also be used as a current collector for other cathode material systems.
