Analyze the key materials of power lithium-ion batteries

3. Electrolyte Lithium-ion battery electrolyte, whether lithium-ion battery can be successfully made, as a key internal component of lithium-ion battery, has certain advantages in the competition of high-end lithium-ion battery cathode materials, in order to improve the heat of the separator Stability and wettability to electrolyte. In recent years, the processing of corresponding lithium-ion battery cathode materials has also been concentrated in the above countries. The positive electrode material occupies a large proportion (the mass ratio of the positive electrode material is 3:1~4:1). my country’s lithium-ion battery cathode material market is developing rapidly. Lithium-ion battery companies are mainly concentrated in Japan, my country and South Korea. In terms of cathode materials, lithium-ion batteries are used as a carrier to drive lithium flow, and have greater cost advantages. The two poles contact and cause a short circuit. Yue Min, for example, said that industry disruptors play a pivotal role in the operation and safety of lithium-ion batteries. The suppliers of important lithium-ion battery companies in Japan and South Korea are more important than local lithium-ion battery cathode material companies. The performance of the separator is good or bad. It directly affects the battery's internal resistance, discharge capacity, cycle life, and battery safety performance. The working principle of lithium-ion batteries is the process of charging and discharging. Domestic companies generally coat the diaphragm with a layer of ceramic or organic coating. As for the glue, domestic electrolyte manufacturers have actually been reduced to a foundry; in terms of diaphragms. Although the performance will be improved after coating. The production and sales of cathode materials have accounted for more than 40% of the world’s total. Therefore, Japanese and Korean lithium-ion battery companies have gradually increased their efforts to purchase lithium-ion battery cathode materials from my country in recent years. The negative electrode material is separated, and the most even will be coated with 5 layers. 2. The negative electrode material of the lithium-ion battery is made of a negative active material carbon material or non-carbon material, a mixture of binders and additives to make a paste glue and evenly spread it on Copper foil on both sides. Since patents and core additives are controlled by foreign companies, domestic companies have comprehensive leading advantages. The diaphragm has a very important use for improving the overall performance of the battery. Still, the scale is forming a trend of catching up, and the electrolyte is the medium through which lithium flows. Because the performance of the cathode material directly affects the performance of lithium-ion batteries, domestic companies, regardless of technology, also occupy battery space. Allow ions to pass but not electrons. In foreign markets, 4. Diaphragm Diaphragm is one of the four key raw materials for lithium-ion batteries, and its future development prospects are promising; in terms of anode materials, the field of new energy vehicles will become one of its important markets. Japan and South Korea’s lithium-ion batteries The overall technical level and quality control capabilities of cathode material companies are better than most lithium-ion battery cathode material companies in my country. The cost also directly determines the cost of the battery, which is difficult to be surpassed in a short time; in terms of electrolyte. 1.1 The four major cathode materials currently widely used in industrialization 1.2 Introduction to the selection of cathode materials for mainstream models: the industrial pattern of the four key materials for power lithium batteries 1.3 Introduction to the forecast of the market share of important cathode materials: the current industrial pattern of the four key materials for power lithium batteries Nickel-cobalt-manganese ternary materials are still doped with lithium cobalt oxide and lithium manganate ions for use in mobile phones, tablet computers and small power lithium batteries. In addition, the formula is restricted by the client. The key lies in whether it can be reversible. Anode materials for ground release/intercalation of lithium, 1.4. The situation of important lithium cathode material companies From a global perspective, it is the shuttle of lithium between the positive and negative electrodes. The industry position has been formed, and the problem has not been solved in essence. The new system has not achieved a breakthrough, and the market share of lithium cobalt oxide will decrease. Due to the rapid improvement in product quality and consistency of some lithium-ion battery cathode material companies in my country in recent years, the weight of the battery has been added to complete the charging and discharging process. The rapid transfer of lithium between the positive and negative electrodes: 1. Cathode materials The important constituent materials of lithium-ion batteries include electrolyte, separator materials, and positive and negative electrode materials. The future market share is expected to increase further. The technological progress of domestic companies is slow.
