Technical problems restrict the development of domestic lithium-ion battery industry

In a specific concept, in the power lithium-ion battery technology, all the information technology to be imported is high technology, otherwise it should not be imported, so the price form of a complete product is displayed as high or low depending on the quantity of imported components.

There are four types of key information for Li-ion batteries: positive electrode, negative electrode, electrolyte, and gap. This information can be isolated when assembled into a power lithium battery. In terms of power lithium batteries, the import of electrolytes and gaps has pushed up and continues to push up the cost of power lithium-ion batteries, which in turn has led to the stagnation or even backwardness of related domestic industries.

At present, the gap, electrolyte, positive electrode data, and negative electrode data account for 85% of the battery cost of the total power, except about 25%, 15%, 30%, 15%, the electrolyte data to be imported, the lithium method is the most An important raw material for the production of electrolyte, accounts for about 50% of the cost of electrolyte. At present, there is only lithium hexafluorophosphate in the world. Japan has realized industrialization in my country, but the key technology is mastered by several Japanese companies in Kanto Electrochemical Industry and Morita Chemical. In China, there are only golden high-tech Co., Ltd., Tianjin Chemical Design and Research Institute, Tianjin, etc. A few companies can produce Taurus, but the capacity is low, and there is a big gap between the quality and foreign countries. As a result, my country's lithium hexafluorophosphate relies heavily on imports, and the pricing power is monopolized by Japanese companies.(Lithium - Ion Battery Equipment)

Another lithium-ion battery has a higher content of technical barrier materials and is highly dependent on imports. This is because the domestic consistency is poor compared with foreign excellent barrier films, and the use of domestic important differences in barrier films will lead to batteries. The quality is unstable, especially the parameters required in the field of power lithium-ion batteries must be highly uniform in each cell, which is difficult for domestic companies to solve. Many domestic companies spend a lot of time looking at the market, not technology, or even the incompleteness of the market, which has led to some misjudgments. It is this incomplete understanding that makes companies affect the development of domestic industries because of the high cost of imported technology.
