Industrial Grade Lithium Hydroxide For Ternary Batteries
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. In addition, the production methods of lithium hydroxide include "Gouhua Fa" and "one-step Fa", with domestic enterprises mostly adopting the latter to improve product quality but increase investment costs.
1、 Advantages of industrial grade lithium hydroxide
Cost advantage
The purity requirement for industrial grade lithium hydroxide is relatively low (≥ 99%), the production process is relatively simple, and there is no need for complex purification steps. The production cost is about 30% lower than that of battery grade products.
In the field of low-end energy storage batteries or non power batteries (such as lead-acid battery alternatives), the use of industrial grade lithium hydroxide can significantly reduce material costs.
Supply stability
Industrial grade lithium hydroxide has sufficient production capacity and a wide range of raw material sources (such as direct calcination of ores), which can meet large-scale production needs in the short term and avoid the risk of supply chain shortages.
2、 Disadvantages of industrial grade lithium hydroxide
Performance limitations
High impurity content (such as metal impurities such as Fe and Na) can easily lead to structural defects in the positive electrode material of lithium-ion batteries, reducing battery energy density and cycle life (reducing cycle times by 20% -30%).
Unable to meet the sintering requirements of high nickel ternary materials (NCM811/NCA), residual impurities at high temperatures can damage the positive electrode crystal structure and affect battery stability.
Security risks
Metal ions (such as Fe ² ⁺) in impurities may cause internal side reactions in batteries, leading to an increased risk of thermal runaway, especially in fast charging or high rate discharge scenarios where safety hazards are greater.
Limited application scenarios
Only applicable to fields with low requirements for electrochemical performance (such as low-end energy storage and backup power), and cannot be used for high-energy density power batteries such as new energy vehicles and aerospace
