Tianshan Aluminum announced on the evening of July 13 that Jiangyin Xinren Aluminum Foil Technology Co., Ltd., a wholly-owned subsidiary of , plans to invest in a new phase with an annual output of 200,000 tons of battery aluminum foil , and implement battery aluminum foil technology with an annual output of 20,000 tons. Change project.
Specifically, the project includes an investment of 800 million yuan in Shihezi, Xinjiang, to build a battery aluminum foil blank production line with an annual capacity of 300,000 tons; an investment of 2 billion yuan in Jiangyin, Jiangsu, to build a battery aluminum foil finishing rolling, carbon coating and slitting production line with an annual capacity of 200,000 tons; Invest 100 million yuan to upgrade the original aluminum foil production line of Jiangyin Xinren Aluminum Technology Co., Ltd. to create a 20,000-ton power battery aluminum foil production capacity.
Power battery aluminum foil is currently a key material in the field of new energy vehicle power batteries. With the huge opportunities for change in the energy field, new energy batteries are widely used in various fields.
Tianfeng Securities predicts that global demand for lithium battery aluminum foil will be 320,000 tons in 2022 and reach 970,000 tons in 2025, with a compound growth rate of 48%. In addition, aluminum foil is used for both the positive and negative current collectors of sodium-ion batteries. If commercialized and scaled up, the demand for aluminum foil is expected to significantly increase in the future.
It is worth noting that lithium battery aluminum foil technology is difficult and has high added value. Currently, there are only a few companies in the market with certain production capabilities. The scale and speed of production expansion cannot match the scale and speed of expansion of power batteries, and the overall supply and demand are tight. Driven by demand for
, companies continue to accelerate production expansion. In January this year, Dongguang planned to invest 2.71 billion yuan to build a low-carbon high-end battery aluminum foil project with an annual output of 100,000 tons in Yidu City, Hubei Province. In the same month, Wanshun New Materials disclosed a plan to issue stocks to specific targets, with the total amount of funds planned to be raised not exceeding 1.7 billion yuan, which will be used for the annual production of 100,000 tons of power and energy storage battery foil projects and to supplement working capital.
Some people in the industry believe that with the release of new battery aluminum foil production capacity, there may be overcapacity in battery aluminum foil in 2024-2025.
However, from the perspective of the lithium battery production process, the production cycle of new battery foil is about 2-3 years. Generally, the average investment to produce 10,000 tons of battery aluminum foil is about 160 million yuan, and the production cycle is about 28 to 36 months. 's high investment and long cycle will undoubtedly limit future supply to a certain extent, and the relationship between supply and demand is difficult to determine in the short term.
