Are there any Japanese materials in lithium batteries?

Among the lithium-ion battery materials, Japan has absolute advantages in materials: lithium hexafluorophosphate, aluminum plastic film, protective IC, and tab glue. 1. Lithium hexafluorophosphate, also known as lithium salt, is mainly monopolized by three Japanese companies, namely: Morita Chemical, Toda Denka, and SUTERAKEMIFA. These three companies account for 40%, 25%, and 10% of the market share respectively; the material cost of lithium salt Only 50,000 RMB/ton, and the processing cost is 100,000 RMB/ton. However, the price of Japan sold to China is about 350,000/ton. You can calculate how much the gross profit has reached. In addition, the friends must have seen the The remaining 25% of the market is occupied by other manufacturers. By the way, our hope lies in this 25% of the market. At present, many manufacturers in China and South Korea are processing lithium salt. The representative manufacturers are: South Korea’s Weishan , Formosa Plastics, Tianjin Jinniu, Polyfluoride, Jiujiujiu, Tianci, Cathay Pacific, etc., also have a small amount of products out every year. Among them, the annual output of Tianjin Jinniu reaches 500 tons, the annual output of South Korea’s Weishan is 200 tons, and the annual output of polyfluorine is also 200 tons. Several other companies also have mass-produced products. Although these products are only used in China Low-end batteries, but better than useless ones. Compared with Japanese products, the performance of domestic lithium salt will definitely decrease after being applied to the battery, but it is also an option. 2. Aluminum-plastic film DNP and Showa account for more than 90% of the market. The products and gross profit of these two companies will not be detailed; the alternative product is Lichon, South Korea. Although the depth of the pit is slightly worse, it is substituted Japanese products are sufficient, and several domestic companies are actively researching and developing, such as Funan Yinyu in Hong Kong (samples are already available), and some manufacturers in Anhui are also trying. 3. The protection IC is mainly monopolized by Japan's Ricoh and Seiko, and brands such as Sanyo and Meizhimei also have a certain market; but there are also several Taiwanese companies in processing, mainly Hongkang, Fortune, etc., and Taiwan's products are also used well. , The price is much cheaper; Continental Coslight also has mature products. When everyone chooses to protect ICs, try to choose domestically produced ones, which can greatly reduce costs and promote the development of Chinese companies. 4. Tab Glue Glue basically relies on Japan. DNP, Showa, Toppan, Hitachi, etc. are the main tab glue suppliers. The domestic ones seem to have never heard of it, sad; but everyone, take a look, they are generally made of aluminum plastic. All the membranes are made of lug glue, and it is believed that in the near future, lug glue will also be made domestically. If you know who is doing research and development in China, let us know to facilitate the process of localization!
