Further explanation of the production process and flow of lithium carbonate

With the intensification of global environmental problems, countries and enterprises have accelerated the pace of human society's transition to a clean and energy-efficient society. Among them, the development of electric vehicles has made great contributions to fresh air and reducing carbon emissions, occupying an important position in the new energy industry. At present, domestic car companies are accelerating the layout of power batteries, and downstream demand is forcing higher and higher requirements for materials and processes of power batteries. Lithium batteries are mainly composed of four parts: positive electrode active material, negative electrode active material, electrolyte, and separator. Among them, carbon material is commonly used as the negative electrode active material, and lithium based materials dominate the positive electrode material. So, what is the development stage of lithium containing minerals as upstream raw materials for positive electrode materials, and what are the developments in lithium extraction processes?

Lithium carbonate is the most important lithium salt in lithium compounds and is the main raw material for preparing high-purity lithium compounds and lithium alloys. It has broad application prospects in fields such as glass and ceramic manufacturing, medicine, non-ferrous metal smelting, and lithium battery electrode materials. At present, the main raw materials for producing lithium carbonate include spodumene, salt lake brine, seawater, etc. Due to different production materials, the production process also varies.

1、 Research status and industrial chain of lithium carbonate at home and abroad

In recent years, China has been actively developing lithium resources in salt lakes. However, due to the high magnesium content in salt lake brine in China, it is difficult to separate magnesium and lithium, and there has not been large-scale industrial production in the past few years. Therefore, China has been extracting lithium salts from lithium ores. Due to the significant differences in the properties of different lithium minerals, the processes for extracting lithium carbonate from lithium minerals also vary. The main processes are as follows.
