Battery Aluminum Foil

Our Battery Aluminum Foil adopts 1XXX series pure aluminum alloys including 1060, 1070, 1100 and 1235, supplied in rigid H18 hard temper to reach tensile strength above 180MPa, fully meeting the high-strength demand of power battery production. This Battery Aluminum Foil focuses on ultra-thin lightweight upgrading: mainstream thickness covers 10–20μm, and we support advanced thin gauges of 8μm & 6μm to lift battery energy density effectively.

Strict thickness tolerance of ±2% eliminates uneven coating risks for this Battery Aluminum Foil. Zero pin-hole production standard avoids internal micro-short circuit of cells, with clear limits on maximum pin-hole diameter. The foil surface is free of aluminum dust, grease and scratches, with dyne value over 32mN/m to secure stable adhesion during electrode coating. Custom width ranges 400–1320mm, featuring excellent electrical conductivity and corrosion resistance, the standard cathode current collector raw material for lithium-ion battery manufacturers worldwide.

Our high-purity H18 temper Battery Aluminum Foil serves as core cathode current collector for all types of lithium batteries, widely mass-purchased by new energy battery factories across four major application fields, with stable thin-gauge performance solving core production pain points.

1. Power Lithium Battery For New Energy Vehicles

This ultra-thin 6–20μm Battery Aluminum Foil is the key raw material for EV power cell cathodes. High tensile strength ≥180MPa resists breakage during high-speed coating and winding procedures, while ultra-tight ±2% thickness tolerance guarantees consistent electrode load. Zero pin-hole design effectively prevents cell micro-shortage and safety hazards, making this Battery Aluminum Foil the mainstream choice for passenger car, commercial vehicle and truck power battery production lines.

2. Energy Storage Station Battery

For grid energy storage and household energy storage battery packs, this Battery Aluminum Foil delivers outstanding corrosion resistance and uniform conductive performance. Clean oil-free surface with dyne value over 32mN/m ensures long-term stable bonding of active materials, extending the cycle life of energy storage cells. Wide customizable width up to 1320mm improves factory winding efficiency and cuts material waste in large-capacity storage cell manufacturing.

3. Consumer Electronic Lithium Battery

The 8–12μm thin-spec Battery Aluminum Foil perfectly matches small lithium cells for smartphones, laptops, tablets and wireless earbuds. Ultra-light thin gauge raises battery capacity within limited casing space, high flatness fits compact automated winding equipment, and zero pin-hole control reduces defective rate of tiny consumer batteries drastically.

4. Industrial & Special Equipment Lithium Battery

For AGV robots, medical devices and aerospace backup batteries, this 1XXX series Battery Aluminum Foil balances high conductivity and mechanical toughness. H18 hard temper avoids foil deformation under frequent charge-discharge cycles, super clean surface meets strict electronic-grade production standards, supporting customized slitting width to adapt small-batch special battery production demands.

We provide full tailor-made Battery Aluminum Foil solutions to match different lithium battery production line standards. Buyers can select 1060, 1070, 1100 or 1235 pure aluminum alloy, all produced in H18 hard temper to maintain tensile strength over 180MPa. This Battery Aluminum Foil supports full thickness customization: conventional 10–20μm mass stock, plus advanced ultra-thin 6μm & 8μm options to boost battery energy density.

All customized Battery Aluminum Foil maintains ±2% strict thickness deviation and zero pin-hole standards, with surface dyne value stably above 32mN/m. Custom slitting width ranges from 400mm to 1320mm to fit various winding machine sizes. Free pre-order samples are available for pin-hole, tensile strength and coating adhesion testing. Flexible international trade terms simplify bulk import procedures for all battery manufacturers sourcing our customized Battery Aluminum Foil.

Every jumbo roll of Battery Aluminum Foil is individually wrapped with dust-proof & moisture-proof plastic film to shield the ultra-clean surface from aluminum dust, grease and oxidation during transit. This Battery Aluminum Foil roll is fixed on dedicated metal core shafts, then padded with shock-absorbing foam and loaded into sealed export wooden cases to avoid extrusion deformation and surface scratch damage.

Multiple packed cases are stacked on fumigated export pallets and fully wrapped with stretch film for stable loading. Clear labels marked alloy, thickness, width and dust-free fragile warnings are attached outside each package of Battery Aluminum Foil. We cooperate with reliable global logistics providers for sea freight, complete customs clearance inspection documents are attached to each batch, guaranteeing this high-standard Battery Aluminum Foil arrives dust-free and intact for your lithium battery production.
