After the rapid expansion of the production capacity of lithium carbonate, the price began to decline from April 16, and the price of lithium hydroxide has always maintained a high level. The price difference between the two is currently 42,000 yuan/ton. Nickel triple materials have become the development trend of positive plate materials. If the price of lithium hydroxide continues to rise and lithium carbonate prices remain unchanged, the price difference will be increased, and the processing profit of lithium hydroxide processing will increase.

　　Policy -driven, lithium hydroxide replace lithium carbonate or become mainstream trends

　　Lithium hydroxide is used to make high nickel tripular materials have higher energy density and better charging and discharge performance. At present, most of the co -sedimentation methods are adopted in the production of high three yuan positive materials. Taking NCM ternary as an example, first use nickel salt, diamond salt, manganese salt to mix, add sodium hydroxide, ammonia, and complexing agents to precipitate, obtain a triple front drive, and burn through lithium carbonate or lithium hydroxide. Get the positive electrode material.

　　Lithium hydroxide replaced lithium carbonate has become a trend. In the migration process, due to the cost of lithium carbonate is generally lower than lithium hydroxide, most manufacturers used lithium carbonate as lithium source materials. Theoretical research shows that the use of lithium hydroxide as a lithium source material, the first discharge capacity is as high as 172mAh/g, and it has better vibration density, and has a greater power charging and discharge performance. Therefore, many high -nickel three yuan materials such as NCM811 and 523 will gradually use lithium hydroxide to replace lithium carbonate.

　　Lithium hydroxide has high nickel triple yuan, and the theoretical discharge capacity is as high as 172mAh/g. It can improve the density of the material vibration. It has better charging and discharge performance, and its advantages are obvious. At the same time, the latest subsidy policy has given a higher subsidy coefficient to high -energy density vehicles, becoming an important force driving the development of high nickel ternary yuan; the proportion of the amount of three yuan in the market is expected to steadily increase, and demand will grow quickly.

　　New lithium hydroxide production capacity is limited, and the rapid growth of demand is expected to promote the steady increase in prices and is conducive to the rise in the profit market for battery -level lithium hydroxide.

　　The latest subsidy policy stimulates the development of high -energy density batteries. In terms of passenger cars, the latest subsidy policy gives subsidies at 1.1 times the quality and energy density than 120Wh/kg. In terms of buses, the latest subsidy policy gives different subsidy adjustment factor for different energy density of the car. On the whole, new energy vehicles with higher energy density will receive high policy subsidies and become an important driving force for the development of high -nickel ternary batteries. And high -energy density high nickel three yuan must be usedLithium hydroxide, so lithium hydroxide instead of lithium carbonate may become a trend.
