As China's ultra-thin aluminum foil leading manufacturers,
YHHX Aluminium Foil Technology Group has begun the R & D and production of new materials for new energy vehicle power battery aluminum foil in 2016.
On July 02, 2019, relying on the world's leading ultra-thin aluminum foil production technology, the company plans to invest 491 million yuan in an annual output of 35,000 tons of new energy power battery aluminum foil project has begun construction.
In the aluminum foil industry, aluminum strips having a thickness of less than 0.2 mm are generally referred to as aluminum foils, and aluminum foils having a thickness of less than 0.0055 mm are referred to as ultra-thin aluminum foils. The thinner the aluminum foil, the greater the technical difficulty of production and the higher the added value of the product. "The processing cost of ultra-thin aluminum foil is 4-5 times that of other products. The 0.0045 / 0.005 mm ultra-thin aluminum foil produced by YHHX aluminum foil technology company is currently mainly used for the production of high-end power and electronic capacitor products. How thin is 0.0045 mm? It is equivalent to 1/16 of the diameter of our hair, and it can be described as "thin as cicada wings".
As far as the entire aluminum foil industry is concerned, there are very few companies in the world that can produce ultra-thin aluminum foil in batches. YHHX aluminum foil technology's original casting and rolling method can not only complete stable and mass production, but also have the characteristics of short process and low energy consumption. Generally, aluminum foil manufacturing uses a hot rolling process, that is, electrolytic aluminum is processed into aluminum ingots, and then hot rolling is processed into thicker aluminum strips, and then processed into thinner aluminum foils. The casting and rolling rule is to directly cast and process electrolytic aluminum liquid into high-precision ultra-thin aluminum foil. The energy consumption is only half of the hot rolling process, and the manufacturing time is only 1/3 of the hot rolling process. Each ton of aluminum foil produced can reduce the power consumption by about 800 kilowatts. Time.
Ultra-thin aluminum foil products are highly in line with the needs of developed countries in Europe and the United States for the miniaturization and lightweight of capacitors. US companies such as GE (General Electric) and Swiss ABB have long purchased from YHHX aluminum foil technology companies. Zhou Yong said: "There are not many companies in the world that can produce ultra-thin aluminum foil, and we have full say in technology and market."
Based on the consideration of good green development potential of new energy vehicles, YHHX aluminum foil technology company has focused on the research and development of new products on battery foil for new energy vehicles. In January 2016, Haoxin Aluminum Foil Co., Ltd. set up an aluminum foil development project team for battery current collectors. The goal is to develop new aluminum alloy formulas, etc., and explore a set of technologies that can produce new types of aluminum foils for lithium ion battery current collectors. Localization.
Based on good market prospects, this product of YHHX aluminum foil technology company has attracted partners with strong advantages to participate in the development and production. With the advancement of the industrialization of this product, the aluminum foil for 0.009mm double-sided photolithium ion battery current collectors will become another core product after the ultra-thin aluminum foil.
In 2018, YHHX Aluminum Foil Technology's aluminum foil production capacity was 15,000 tons. "Our production line has to be built while producing, and the market demand is great." Zhou Yong said that the aluminum foil production line has been completed and the annual production capacity is 36,000 tons. After the completion of the aluminum foil project for energy and power batteries, the entire aluminum foil capacity demand will reach 7 10,000 tons.
