Lithium battery anode foil is a material used for the positive electrode collector of lithium batteries.  The thickness of aluminum foil is generally between 10 and 50 microns.The material for lithium battery anode aluminum foil is usually high-purity aluminum, with various alloy grades such as 1060, 1050, 1145, and 1235.These aluminum anode foils have high purity, ensuring the electrochemical performance and stability of the battery.Including -O, H14, -H24, -H22, -H18 states.

The anode aluminum foil has the following characteristics:

Uniform thickness:

The thickness of lithium battery aluminum foil is usually between 10 and 50 microns, with uniform thickness and high precision, which can ensure the capacity and life of the battery.

The surface is smooth and flat:

The surface of the lithium battery negative aluminum foil is smooth and flat, with no color difference, no serious oil odor, no visible oil spots, and a surface tension of not less than 32 dyne.It ensures the electrical contact and charging efficiency of the battery.

Strong corrosion resistance:

The aluminum foil for lithium battery anode has good corrosion resistance and can resist the corrosion of various chemical substances, thus ensuring the stability and longevity of the battery.

Strong adaptability:

Lithium battery anode foil can adapt to a variety of different battery structures and manufacturing processes, with a wide range of applications.

Physical properties:

The aluminum foil should be wrapped tightly, with smooth and clean end faces and smooth edges;the aluminum foil staggering should not exceed ±1.0mm;the width of the aluminum foil core should be greater than or equal to the width of the anode foil, and the length of the two ends of the core should generally not exceed 5mm of the width of the foil;the aluminum foil should be wrapped around the center of the core;there should be clear joint marks at the connection points on both ends of the reel.

In general, lithium battery anode foil has the characteristics of high quality, high precision, and high safety, and is an indispensable and important material in the manufacture of lithium batteries.
