Do you know the development prospects of lithium battery recycling?
With the development of electric vehicles, the demand for recycling of lithium batteries will increase, and the current publicity has never mentioned the disassembly of lithium batteries after recycling. What is the current situation of domestic lithium battery recycling industry?
Today, let's take a look at the whole process of lithium battery recycling.
1. It is to split and crush the lithium-ion battery for pretreatment. Wrong, this is a wrong step. What we should do first is to completely discharge the recycled lithium battery. There are two discharge methods. One is that the physical discharge is a short-circuit discharge, which is cooled with liquid nitrogen at low temperature, and then forcibly discharged through perforation. Second, chemical discharge is electrolytic discharge with a conductive solution. Obviously, the chemical method is low in cost and can be industrialized on a large scale.
To be green and efficient, electrolyte is the secret of each family. Whether it can be green depends on conscience. The lithium battery must be broken first. After screening, the electrode material is obtained, and these are regular operations. Lithium cycle technology allows mechanical comminution without emissions. The next step is hydrometallurgy, which dissolves and leaches the electrode material, making it rich in various metals and chemicals that enter the leachate in the form of ions.
3. The key technology of the third link is to separate and recover the valuable metals in the leaching solution. There are many methods, and each company depends on its ability. Some enterprises have strong technology, which can make the recovery rate of effective substances of lithium batteries reach more than 80%.
At present, with the explosive growth of new energy vehicles, the penetration rate has increased year by year, and the sustainable development of power batteries has also attracted the attention of all sectors of society. Including carbon emissions in the manufacturing process of power batteries and the disposal of used batteries, this is one of the key issues that the industry urgently needs to solve and improve in the future. At the same time, the rapid development has also brought many problems. The sharp increase in battery production has stimulated a cyclical rise in raw material prices. At present, the prices of many major raw materials have risen more than once or several times, resulting in a shortage of material resources in the industry, which is not conducive to the long-term and stable development of the industry.
Therefore, the demand for raw materials for the development of lithium batteries in China is relatively passive. In recent years, many Chinese companies have gone to sea to arrange or purchase good resources to stabilize future supply and industry status. At the same time, the recycling of power batteries is also an important part, which can be used as an effective way to supplement raw materials. Recycling can reduce the energy consumption and emissions of production, which is more in line with the definition of green energy.
Economic benefits are one of the important driving forces to promote the development of the recycling market. The shortage of raw materials and the rapid rise in prices have made many battery companies pay attention to the benefits of the recycling market, which can reduce costs. Lithium battery companies, material companies, recycling companies, etc. form a closed-loop business model through cooperation, which can not only achieve environmental protection, but also help companies reduce costs. In the future, the domestic lithium battery recycling business will usher in a large-scale development stage.
