Battery Aluminum Foil Price

The battery aluminum foil price quoted by Haomei Aluminum can be regard as the most reasonable one regards of high quality and good after sale service. The current alloys used for battery aluminium foils are mainly: 1070, 1060, 1235, 1230, 1100, 8011, 3003, 1N30, etc., covering almost all alloy varieties used in aluminum foils, but the most used are 1235, 1060, 1070 industrial pure aluminum, 1100, 3003 aluminum alloys are mainly used to produce ultra-high strength battery foil.

Battery aluminum foil is a deep-processing product of aluminum foil, so production is much more difficult than ordinary aluminum foil, so the battery aluminum foil price is higher than that of ordinary aluminium foil, and there are many key technologies. First, the thickness requirements of battery aluminum foil are strict. The nominal thickness of the battery foil is getting thinner and thinner, it is hoped to achieve a double-sided finish of 9 μm or even 8 μm, which has exceeded the minimum rollable limit thickness of the current single-sheet rolling of aluminum foil products. Moreover, the thickness accuracy is required to be ±2%, which is the highest among all aluminum foil products at present. However, it is not difficult for China to produce such thin aluminum foil, and some battery aluminum foil manufacturers have long been able to produce 4μm aluminium foil.

Recently, general battery foil products generally require a strength of ≥180MPa, which is already equivalent to the performance of 8000 series aluminum alloys. With the continuous development of battery technology, due to various considerations, many users are constantly increasing the strength requirements of battery aluminium foil products. At present, the strength requirements of more than 200MPa are very common, and some users even require strengths of 270MPa or even 300MPa. The strength limit of cold hardening of aluminum foil products has been reached, and its production is extremely difficult. This is also another factors that affect the battery aluminum foil price.

In order to meet the needs of the coating process and the carbon coating process, the battery foil has high requirements on the surface dyne value, but the high surface dyne value control is contradictory to high strength, and the extremely high plate shape requirements and thickness difference are both contradicting with high-strength ultra-thin rolling, that is to say, battery aluminum foil requires the thinnest thickness, highest strength, highest surface dyne value, smallest thickness difference, optimal plate shape, and cleanest surface, to pursue these six extreme values.
