The new energy vehicle market has begun to rise in 2014, and the new energy vehicle has appeared during the 2008 Olympic Games. According to the corresponding scrap standards, the power lithium battery scrap cell market has begun. It is estimated that by 2018 my country's motivational lithium iron phosphate was originally The waste recycling market will begin to start a scale, accumulated 12.

08GWH of the use of waste power lithium batteries, and the accumulated scrap will reach around 1.72,500 tons. According to the measurement, the number of recovery markets created by the recovery of cobalt, nickel, manganese, lithium, iron and aluminum and aluminum in the waste dynamic lithium-ion battery will reach 5.

323 billion yuan, reaching 10.1 billion yuan in 2020, 2023 waste The power lithium-ion battery market will reach 25 billion yuan. Lithium-ion battery recovery is social responsibility, lithium-ion battery environmentalization, harmless disposal, in line with sustainable development.

Therefore, the government has implemented producers' responsibility extension, requiring producers to be responsible for battery recovery, guaranteeing battery source controllable, clear-to-clear, in order to mitigate the workload of recycling dismantling links; while advocating the form of the Pack Battery Group, Reduce recycling difficulty and improve industry efficiency. How to recover the lithium iron supply of iron phosphate? Lithium-ion battery recovery 1, the ladder use with the raw material recovery retire power lithium ion battery, take the road to use the road, is the ladder after use, the material is recovered; the direct material recovery is too small, no history, safety monitoring Unqualified, etc. Pursuing economic benefits is the driving force of companies and social behavior.

According to the truth, the ladder is used, and the available value to the battery is reduced to the maintenance cost, and then the raw material recovery is the maximum battery value. However, the actual situation is that the early dynamic lithium battery is traceable, quality, model is uneven. Early battery's ladder is high, and the cost of eliminating the risk is high.

Therefore, it can be said that in the early stage of the power lithium battery recovery, the battery's goal is mainly based on raw material recovery. 2, the positive electrode material value metal extraction method The current power lithium ion battery recovery, in fact, there is no comprehensive recovery of various materials on the battery. The types of positive electrode materials include: lithium cobaltate, lithium manganate, three-dimensional lithium, lithium iron phosphate ion battery, etc.

Battery positive material costs occupy a monomer battery cost 1/3 or more, and because the negative electrode is currently using more carbon materials such as graphite, there is less application of lithium titanate Li4TI5O12 and silicon carbon negative electrode Si / C, so the current battery recovery technology is important for Is battery positive material recycling. Recycling method of waste lithium ion batteries Important physical law, chemical method and biological law three categories. Compared with other methods, wet metallurgy is considered to be an ideal recovery method due to its advantages of low energy consumption, high recovery efficiency and high product purity.

Lithium-ion battery 1 Physical method physics method is treated with lithium iron phosphate ion batteries utilized by the physical chemical reaction process. Common physical chemical treatment methods are important to crush flotation method and mechanical grinding method. 2 Chemical method is a method of treating a lithium-ion battery using a chemical reaction process, and is generally divided into two methods of fire-based metallurgy and wet metallurgy.

3 Biological Biological Metallurgical Law is currently in progress, which uses the metabolic process of microbial bacteria to achieve selective leaching of metal elements such as cobalt and lithium. Biological energy consumption, low cost, and microorganisms can be reused, the pollution is small; however, the requirements for cultivating microbial bacteria requirements, long culture time, low leaching efficiency, and process to be further improved. The current powerful lithium-ion battery is important to recycle small workshops, professional recycling companies and government recycling centers, and have not appeared in the recycling system of power lithium battery production companies or electric vehicles.
