Today, most electronic devices such as smart phones, tablets, wearable devices, electric vehicles are used in recyclable lithium-ion batteries. However, these lithium-ion batteries use two to three years, and function and efficiency will degrade, even ending life. At this time, you must consider the problem of recycling and reuse.

Recently, published a new study in International Energy Technology and Policy magazine, describing a new method can extract lithium and cobalt from these batteries, which constitute most of the battery packs. Method According to the Interpretation of the Mechanical Engineering Department of Malaysia International University, the interpretation of Rafiaafroz, the manufacture of lithium ion batteries, two metals to lithium and cobalt, so the prices of these two metals are increasing. At present, they have developed a new type of recovery technology that can effectively extract these metals from waste batteries.

The process team uses wet metallurgy technology, in the laboratory stage test, can reduce cobalt and lithium from the 48.8WH lithium ion battery. This process includes: First, baking batteries in 700 degrees Celsius, "calcination" cobalt, lithium, and copper, destroy organic compounds such as plastic and foam.

Such calcined materials carry metal and metal compounds (salt and oxides), then strong acid, hydrochloric acid, and sulfuric acid, extract metal ions. The team uses hydrogen peroxide as a reducing agent to test whether such reagents can improve the leaching process. They can extract lithium with about 50% efficiency, extract cobalt with about 25% efficiency.

Feasibility Because these metals represent 41% and 8.5% of the 48.8 WH battery, the overall extraction rate is high, and the use of heat and acid is added, and there is a method of business feasibility.

Electrode used to recover these batteries. This leaching metal can then be used to make new batteries or for other industrial applications. This contaminated liquid waste can further carry out more safe recovery.
