[November Thematic Report] Batteries recycling |

Battery experts and environmentalists give many reasons to recycle lithium-ion batteries. Recycled materials can be used to make new batteries, which reduces manufacturing costs. Currently, these materials account for more than half of battery costs. In recent years, cathode metal prices have fluctuated dramatically Most commonly, cobalt and nickel are the most expensive components. The current market prices for cobalt and nickel are about $27,500 per metric ton and $12,600 per metric ton, respectively. In 2018, the price of cobalt exceeded $90,000 per metric ton. In many types of lithium-ion batteries, the concentrations of these metals, as well as lithium and manganese, exceed those found in natural ores, which makes used batteries similar to highly concentrated ores. If these metals can be recovered from used batteries more costly and economically than natural ore, then it should be That the price of batteries and electric vehicles decrease. In addition to the potential economic benefits, recycling can also reduce the amount of materials entering the landfill. Sun Zhi, a pollution control expert with the Chinese Academy of Sciences, said that cobalt, nickel, manganese and other metals in the battery can easily leach out of the battery shell, and pollute soil and groundwater, and threaten ecosystems and human health. The same is true for solutions of lithium fluoride salts (usually LiPF 6) in organic solvents used in battery electrolytes. Not only do batteries have a negative impact on their end-of-life, but they can also have a negative impact before a battery is manufactured. As Gaines of Argonne pointed out, more recycling means less extraction of raw materials and fewer environmental risks. For example, mining requires minerals to process ore Metal sulfide for some batteries, which require a lot of energy and emit SO X, which may cause acid rain. Reducing reliance on extraction of battery materials may also slow consumption of these raw materials. Gaines and Argonne colleagues used computational methods to study this problem to simulate how increased battery production will affect geological reserves of many minerals by 2050. Researchers recognize that these projections are “complex and uncertain.” The researchers found that the world's reserves of lithium and nickel are sufficient to sustain the rapid growth in battery production. But battery manufacturing could reduce global cobalt reserves by more than 10%. Recycling materials of lithium-ion batteries is the key to the development of electric transportation In the future, battery packs won't just come from the mining industry. They have to come from applications that recycle and use industrial side currents. The ability to recycle these materials will lead to the growth of electric vehicles. The limited availability and environmental impact of mining means that recycling these scarce elements for battery manufacturing is critical to minimizing the environmental impact of using batteries throughout their life cycle

Hello, this is your mentor Minkyung.
Thank you for sharing your knowledge of battery recycling. Because we are using so many batteries in our daily lives and in other various areas, recycling batteries will be more and more important.
I'll be looking forward to your next report :)

Hi, Abdelouahab KRIM!
This is your mentor, Yoon.
Thank you for introducing the battery recycling, which is a very important technology to enable a circular economy of battery components.
You also did well in bringing up how manufacturing batteries are harmful to the environment.
Great job on writing the free report.
I am looking forward to reading your following report!
