　　What are the shortages of CR2032 button cell battery materials? How do CR2032 button cell battery manufacturers make breakthroughs in materials? In recent years, CR2032 button cell battery material manufacturers have been squeezed by major international material manufacturers on the one hand, and disorderly price competition caused by overcapacity on the other. The production capacity utilization rate of iron-lithium materials is only less than 10%, and price competition directly leads to a decrease in gross profit margins of material manufacturers and weakened profitability. In order to reduce production costs, large manufacturers continue to expand production capacity, which intensifies industry competition, thus forming an industry-wide Vicious cycle.

　　At present, there are more than 60 domestic companies that have achieved mass production of lithium iron phosphate. Due to the high technical threshold for the production of lithium iron phosphate batteries, most CR2032 button cell battery manufacturers cannot guarantee the stability of their products during mass production. As a result, the number of companies that have achieved mass production is close to 20 companies. According to public statistics, the actual output is far lower than the production capacity. In 2018, the domestic effective production capacity of lithium iron phosphate cathode materials will reach 300,000 tons/year. There will be a significant surplus of lithium iron phosphate material production capacity. The lithium iron phosphate material industry more competitive.

　　What are the shortages of CR2032 button cell battery materials?

　　The main upstream raw materials used in the cathode include: lithium ore, cobalt ore, nickel ore and manganese ore. But even at the industrial research level, manganese is rarely discussed, because the supply of manganese is not a problem, but there is pressure to increase prices.

　　The market demand for CR2032 button cell battery copper foil in my country is still showing a rapid growth trend. Although new companies continue to enter this field and the scale of production capacity is rapidly expanding, it still cannot meet the domestic market demand, especially in the field of lightweight copper foil, where the imbalance between supply and demand is relatively serious. . Although copper is abundant, the production capacity of copper foil production equipment is limited, which affects the speed of production expansion of various manufacturers. In order to meet the demand for increased specific energy of power lithium batteries, there is a large demand for thin copper foil, and the relationship between supply and demand is even tighter.

　　Cobalt resources are in short supply and prices are growing rapidly. In the future, most passenger cars will use ternary lithium batteries, and the demand for cobalt will increase three to four times. The situation in Congo, the origin of cobalt, is not good and will remain tense in the future. Cobalt prices have been on a downward trend in recent years, but the decline has been narrowing year by year, which also indicates that historically high inventories have been significantly improved. Therefore, the current cobalt price is at a historical bottom, the industry is suffering serious losses, and the value may be expected to return reasonably.

　　It can be seen that cobalt and copper foil will continue to be in short supply; lithium iron phosphate cathodes, graphite anodes, and lithium hexafluorophosphate are at risk of excess; although the demand for lithium carbonate is huge, production capacity is gradually released, and the supply and demand relationship will tend to be balanced, and the same is true for lithium hydroxide; in order to meet the high demand In the technical direction of specific energy, lightweight, and fast charging, the demand for high-nickel ternary cathode materials may increase significantly. The demand for wet-process separators is greater than that of dry-process separators. Lithium titanate also has certain room for growth.

　　How do CR2032 button cell battery manufacturers make breakthroughs in materials?

　　Technical breakthroughs in key materials for lithium batteries should mainly depend on application scenarios, and then decide how to break through technical bottlenecks based on the application scenarios. The four key materials of lithium batteries are negative electrode material, positive electrode material, electrolyte and separator. Chinese companies must have the final say on CR2032 button cell battery materials in the future, because Chinese CR2032 button cell battery material suppliers have achieved a leap from "imitation-following-catch-up" and are now on the road to "catching up" one after another.

　　Domestic enterprises in cathode materials are forming a trend of "catching up from behind" in terms of technology and scale, and their future development prospects are promising; in terms of anode materials, domestic enterprises have comprehensive leading advantages, and their industry status has been established, which will be difficult to surpass in the short term; Electrolyte Since patents and core additives are controlled by foreign companies, and the formula is controlled by the client, domestic electrolyte manufacturers have actually become OEMs;

　　In terms of diaphragms, the technological progress of domestic enterprises is slow, the new system has not achieved breakthroughs, and the problem has not been fundamentally solved. The industry needs disruptors. In order to improve the thermal stability of the separator and its wettability to the electrolyte, domestic companies generally apply a layer of ceramic or organic glue on the separator, and even 5 layers at most, although the performance will be improved after coating. , but it also takes up battery space and increases battery weight.

　　Domestic research on lithium titanate materials as negative electrode materials has also been fruitful, improving the specific energy of batteries and reducing costs. Not only does the material have good safety, long life, and high charge-discharge power ratio, but it also has the problem of foreign patent protection.

　　In general, the future development of lithium batteries requires new alternative materials to reduce the volume, increase the storage capacity per unit volume, and increase the charging efficiency per unit time. and cost reduction. Only in this way will battery technology develop.
