Lithium-ion battery manufacturers talk about the current situation of waste lithium battery market and lithium-ion battery recovery technology. With the continued rise of new energy vehicles, there is only a large-scale powerful lithium-ion battery demand, and the industry opportunities for lithium-ion battery recovery and ladder use, develop lithium-ion battery recycling and ladder use in preventing waste of resources Pollution will also have considerable economic benefits and investment opportunities. The following lithium-ion battery manufacturers talk about the current situation of the waste lithium battery market and the recovery technology of lithium-ion battery.

Current status of lithium elements in the waste lithium-eM industry as elements widely used in power lithium-ion batteries, which are widely used, and now the price of lithium carbonate on the mall is constantly high, demand, especially new power car drive, demand expansion, and supply-to-supply production The difficulty of the release is effective in the price of lithium carbonate, which promotes more and more companies to pay attention to economic benefits of lithium-ion batteries. In 2018, it was considered to be the first year of the dynamic lithium battery, driving the rapid rise in the scale of the radical lithium-ion battery, and the use of the waste power lithium-ion battery has become an important rise point of battery recovery. The lithium ion battery of the power vehicle contains a large amount of lithium, manganese, nickel, and cobalt, etc.

, also contains a lower value metal such as iron and copper. Recycling these priceless metals from the power lithium battery has high economic value, while also reduces pollution to the environment. The market size of the 2020 waste lithium battery recycling and ladder is expected to reach 10 billion yuan.

The current powerful lithium battery recovery main body has an important recycling small workshop, professional recycling company and government recycling center, and has not appeared in the recycling system of the power lithium battery production company or electric vehicle company. At present, the recycling channel of the dynamic lithium-ion battery is important to recycle small workshops, and the professional recycling company and the government recycling center are less, the system needs to be reorganized. Most of the waste dynamic lithium batteries have flowed into the lack of qualified refurbishment workshops, these company process equipment is behind.

However, if it is submitted to register the tax payable according to law, the qualifications are obtained and emissions according to national standards will cause the lack of competitiveness. Therefore, it is necessary to improve the sustainable development of the policy to ensure the battery recovery industry. Lithium-ion battery recovery technology 1.

High temperature metallurgical method: High-temperature calcination is simply mechanically crushed by a discarded lithium-ion battery, and the fine powder containing metal and metal oxides is sieved. High temperature metallurgy process characteristics: process is relatively simple, suitable for large-scale processing; battery electrolytes and other ingredients can cause air pollution. Second, wet metallurgy: After breaking the battery, selectively dissolve with a suitable chemical reagent, isolated metal elements in the leaching liquid.

Wet metallurgy process features: good process stability is suitable for the recovery of small and medium-sized waste lithium-ion batteries; high cost, waste liquid needs to be further processed. Third, physics dismantling: divide the battery pack, screened, magnetic separation separation, fine pulverization and classification to obtain high content substance, and then carry out the process of next recovery. Physical dismantling process characteristics: low processing efficiency, low time consumption; process is very environmentally friendly, will not cause secondary pollution to the environment.

In general, the waste lithium-ion battery environment is high, but the recovery value is high, and the metal elements are more scarce, imported rely on higher metal resources. At the same time, for the company, the recycling of waste lithium electricity also contains business opportunities. After effective recovery, it can have a large amount of production costs for battery production, with very high economic value.
