The difference between industrial grade lithium carbonate and battery grade lithium carbonate

Industrial grade lithium carbonate

Industrial grade lithium carbonate refers to the lithium carbonate products used in the industrial field. It is usually made from ore as raw material through a series of ore beneficiation, purification and chemical reaction. The main characteristics of industrial grade lithium carbonate are as follows

1. Lower purity: the purity of industrial grade lithium carbonate is generally around 90%, which is slightly lower than battery grade lithium carbonate.

2. Contain more impurities: industrial grade lithium carbonate may contain more impurities, such as iron, sodium, potassium, etc., these impurities may have an impact on some application scenarios.

3. Wide application: Industrial grade lithium carbonate can be used in glass ceramics, gold treatment, chemical industry and other fields, widely used in various industrial production.

Battery grade lithium carbonate

Battery grade lithium carbonate refers to the lithium carbonate products used in battery manufacturing. Compared with industrial grade lithium carbonate, battery grade lithium carbonate requires higher purity and fewer impurities. Its main characteristics are as follows

1. High purity: Battery grade lithium carbonate requires high purity, usually above 99.9%. High purity lithium carbonate can improve the performance and cycle life of the battery.

2. Low impurity content: battery-grade lithium carbonate in the impurity content requirements are low, especially for some heavy metal ions content requirements are more stringent, so as not to adversely affect the performance of the battery.

3. Specialized use: Battery-grade lithium carbonate is mainly used in the manufacture of lithium-ion batteries, such as cell phone batteries, electric car batteries, etc. Comparison: industrial grade potassium carbonate and battery-grade lithium carbonate.

Industrial grade lithium carbonate and battery grade lithium carbonate have some differences in purity, impurity content and application areas. Industrial grade lithium carbonate is mainly used in industrial production, widely used in dry glass ceramics, gold treatment, chemical industry and other fields, while battery grade lithium carbonate is specifically used in the manufacture of batteries, which requires higher purity and fewer impurities. The purity and impurity content of battery grade lithium carbonate are more stringent to ensure the performance and safety of the battery.
