Anhydrous Lithium Hydroxide
Product advantages
The main advantages of lithium hydroxide products include high specific energy, long lifespan, high stability, and broad application prospects.
High specific energy: Lithium hydroxide has a high specific energy, which allows the battery to store more electrical energy, thereby improving the battery's endurance.
Long lifespan: Lithium hydroxide has stable chemical properties and low self discharge rate, which can reduce energy loss of the battery and extend its service life.
High stability: Lithium hydroxide performs well in extreme environments such as high and low temperatures, reducing corrosion and damage inside the battery and improving its overall performance.
Widely used: Lithium hydroxide has broad application prospects in industrial fields such as electric vehicles, glass, ceramics, etc., especially indispensable in high-performance power batteries.
With the development of clean energy and the introduction of national energy-saving and environmental protection policies, the market demand for lithium hydroxide will continue to expand. Especially in the global trend of automotive electrification, the demand for lithium hydroxide as a battery material will further increase.
The difference between industrial grade and battery grade
Purity and impurity control
Industrial grade lithium hydroxide with a purity of ≥ 99%, suitable for non battery fields such as lubricating grease and developer solutions; Battery grade purity ≥ 99.5%, strict control of impurities such as Fe and Na is required.
The price of industrial grade products is about 30% lower than that of battery grade products, but the level needs to be selected according to the application scenario to avoid performance issues.
Production process optimization
Industrial grade products are often prepared by direct calcination of ores, while battery grade products require further purification (such as ion exchange and recrystallization) to meet electrochemical performance requirements.
