Where to Buy Aluminum Foils for Li-ion Batteries

Publish: Modify: Oct 11, 2022Author: From:  Haomei

Battery aluminum foil is mainly used as current collectors of lithium batteries and sodium batteries. 300-450 tons of foils for li-ion batteries are needed per GWh. Where to buy it with reliable quality?

Battery aluminum foil is mainly used as current collectors in the positive and negative electrodes of lithium batteries and sodium batteries, which have an important impact on battery performance. The internal resistance of the lithium-ion battery directly affects the reliability and cycle life of the battery, which is not only determined by the four main materials of the battery, but also related to the current collector.

The current collector is not only the carrier of the active material, but also the conductor of the current generated during operation, which can form a larger current and improve the charging and discharging efficiency of the lithium battery. According to the actual survey data, 300-450 tons of foils for li-ion batteries are needed per GWh.

Driven by both new energy vehicles and energy storage, the global demand for battery foil is expected to reach 740,000 tons in 2025, with a compound annual growth rate of 37%. Aluminum foil battery price is determined by the method of "aluminum price + processing fee". At present, the thickness of battery foil is between 8-15μm, the mainstream thickness of overseas electric power battery and energy storage field is 15μm.

The thickness and rolling precision of the battery foil are close to those of the traditional light gauge foil. At present, there are two main ways to expand the production capacity of battery foils in the industry: 1. purchase rolling mills and install new equipment; 2. Upgrade the light gauge foil production line to produce aluminum foil for battery. Haomei Aluminum has increased the production capacity of battery foil by adopting the second solution.

Compared with the traditional aluminum foil, the battery foil's requirements on the shape and and accuracy are greatly improved. The aluminum foil has high requirements for tensile strength, elongation strength, pinhole, edge trimming, burr, convexity rate, etc. Leading companies like Haomei Aluminum in the industry have more than 10 years of production experience and R&D accumulation.

The common aluminum foils for battery include 1070, 1235, 1100, 1060, 3003, HL07, HL08,etc. As a special battery aluminum foil manufacturer, Haomei Aluminum has all the main alloys of battery aluminum foils. Welcome to leave message below to inquire aluminum 1100 price and other alloys.
