Wet extractants of precursor materials for ternary lithium batteries

1、 Introduction
In recent years, the development and application of green energy have become an important research direction for global researchers. As one of the important green energy sources, lithium batteries are increasingly widely used in fields such as new energy vehicles and mobile electronic devices. And ternary lithium batteries are the leader among lithium batteries, becoming the preferred power source for many devices due to their advantages such as high energy density and long cycle life. The preparation technology of key materials, namely precursor materials for ternary lithium batteries, has gradually become a research hotspot. This article will focus on the latest technology of wet extraction of precursor materials for ternary lithium batteries.
2、 Overview of Wet Extraction Technology
Wet extraction is a method that uses a solution to treat solid minerals, converts useful components in the minerals into a solution through chemical reactions, and then separates useful components from the solution through chemical methods. Compared to traditional dry extraction, wet extraction has the advantages of thorough reaction, high efficiency, energy conservation and environmental protection.
3、 A New Technology for Wet Extraction of Precursor Materials for Ternary Lithium Batteries
1. Electrochemical wet extraction technology
Electrochemical wet extraction technology is an emerging wet extraction technology that electrolyzes useful elements from ores through electrolytic reactions. This method not only improves extraction efficiency, but also significantly reduces energy consumption, making it a very environmentally friendly extraction method.
2. Biological wet extraction technology
Biological wet extraction technology utilizes the metabolic activity of microorganisms to convert useful elements in ore into extractable substances in solution. This method not only can be performed at room temperature and pressure, but also does not require the addition of any chemical reagents, making it a very green extraction method.
3. Ionic liquid wet extraction technology
Ionic liquid wet extraction technology utilizes the strong solubility and good stability of ionic liquids to dissolve useful elements in ores. This method not only has high extraction efficiency, but also can be carried out over a wide range of temperature and pressure, making it a very flexible extraction method.
4、 Conclusion
The new technology of wet extraction of precursor materials for ternary lithium batteries has great research value and application prospects, whether from the perspective of improving extraction efficiency, reducing energy consumption, and environmental protection. However, at the same time, these technologies also face issues such as high cost, complex equipment, and high operational difficulty, which require further research and improvement. With the in-depth research of researchers on these new technologies, it is believed that there will be more efficient, environmentally friendly, and economical wet extraction methods for precursor materials of ternary lithium batteries in the future.
