Experimenting with a method for recovering metals such as lithium and cobalt that are used
A scientist has taken an environmentally friendly approach to hydrometallurgy. This is one of the modern methods of recovering metals from used batteries for reuse in the production of new ones.
The process typically uses harsh acidson a mineral basis. But to recycle the metals from the cathode—the positive side of the battery—the new method's author is experimenting with milder organic chemicals. They have minimal impact on the environment.

Using mixtures of organic acids, scientistsrecovered more than 80% of lithium from used batteries, and “once this figure approaches the 100% mark, it can be used in industry,” noted the authors of the new study.
Lithium-ion batteries that power everythingfrom mobile phones to electric cars, are part of the daily life of a modern person. The problem is that over time they wear out. And it comes at a huge cost to the environment.
Because over the past decade, wasteSince electrical and electronic equipment has begun to accumulate rapidly, a new approach will solve most of the problems that people face. The concept is also an “ideal model” for solving a number of challenges in battery manufacturing, including cost and dependence on raw material mining for raw material supply.
