　　With the rapid development of my country's new energy vehicle market, the demand for power lithium batteries has increased significantly. As the energy density requirements for lithium batteries continue to increase, the market demand for ternary button battery cr1620 materials has always maintained a growth trend.

　　Whether it is policy orientation, market demand, or technology evolution direction, high nickel content of ternary materials has become an inevitable trend in the development of power button battery cr1620 materials. Against the background of declining subsidies and intensifying international competition, domestic companies are actively deploying in the high-nickel ternary field.

　　button battery cr1620 manufacturers have learned that due to the urgent demand from car companies and battery companies for the introduction of high-nickel ternary materials, the pace of advancement has been accelerating. Since 2018, NCM811 materials have been in serious short supply. In order to meet market demand, domestic cathode material manufacturers are also actively deploying high-nickel products, and these production capacities have been gradually supplied to the market. In particular, the production capacity and output of NCM811 products have attracted great attention.

　　It is expected that global cathode material shipments will exceed 600,000 tons by 2022 and will be close to 1 million tons by 2025. Among them, ternary materials will still account for the majority, and high-nickel ternary materials will also usher in opportunities that rise when the tide rises. From a domestic perspective, the compound growth rate of shipments of ternary button battery cr1620 materials is expected to remain above 30% in the next three years, and shipments will exceed the 200,000 tons mark by 2020.

　　As the core material of lithium batteries, cathode materials will continue to benefit in the future, and the technology of cathode materials is still in the evolving stage and has huge potential. Cathode material companies must not only have technology development and product update capabilities, but also have production capacity to protect them; they must have a stable supply of upstream resources and be recognized by downstream customers. For high-nickel ternary button battery cr1620 companies, it is time to reshape the scattered and chaotic pattern of cathode materials in the future, and leading companies are expected to win.

　　Technical pain points of high-nickel ternary cathode materials

　　The capacity of high-nickel ternary button battery cr1620 cathode materials mainly comes from Ni2+/Ni4+ redox, so the higher the nickel content, the greater the capacity of the material. However, when the Ni content increases, high-nickel ternary cathode materials will bring about a series of difficult technical problems. The main raw material of high-nickel ternary cathode materials is hydroxide precursor, and Ni exists in the form of Ni2+.

　　The high-nickel ternary button battery cr1620 cathode material is structurally unstable at high temperatures, and during the cycle, a cubic rock salt phase is formed that no longer has lithium ion deintercalation activity. The higher the nickel content, the higher the total alkali content. The high total alkali content puts forward higher requirements for its industrial production, storage, transportation and battery preparation. When the material comes into contact with air, the structure, morphology and composition of the powder material change, and the electrochemical performance gradually decreases, especially when exposed to humid air. This phenomenon is particularly obvious.

　　During the preparation and coating process of high-nickel ternary button battery cr1620 cathode slurry, environmental humidity has a huge impact on it. If water absorption occurs during the process, it is particularly likely to cause changes in the properties of the slurry, resulting in unstable quality during the electrode manufacturing process. Problems such as poor process consistency may even make the coating process impossible when a gel slurry is formed.

　　High-priced nickel will react with the electrolyte to release heat and gas, and it is also very unstable. It will decompose and precipitate O2 when heated. When heat and gases such as CO2 and O2 accumulate inside a sealed battery and reach a certain pressure, an explosion will occur.

　　At present, the popular words in the power battery industry are not only "high nickel", but also: "solid-state battery", "lithium-rich manganese-based solid solution material", "lithium-sulfur battery", etc. The emergence of new technologies, new materials and new concepts It will have a certain impact on the application of high-nickel ternary button battery cr1620 materials.

　　The raw material cost of high-nickel ternary button battery cr1620 materials has declined because nickel is cheaper than cobalt. However, these technical pain points of high-nickel ternary materials have led to extremely harsh production conditions, declining raw material costs, and rising production costs. Therefore, the cost of high-nickel ternary materials will not be significantly reduced in the future. However, due to national and market requirements for battery specific capacity, high-nickel ternary materials are imperative.
