Outlook on lithium battery recycling

Source: 2020 - 04 - The ten sons of hits: first lithium battery recycling prospects compared with Japan, Korea, Europe and the United States, the lithium ion battery industry in China in the new product development and recycling is weak. Product production and recycling is an interrelated whole, must have the product recycling. Therefore, in order to reuse the lithium ion battery, the future of our country need to strengthen the research and development of new products and waste recycling. New product development is the key to lithium ion battery electrode materials of basic research. Now than can and cycle life of lithium iron phosphate batteries in there are a lot of limitations, need from synthesis, doping, coating and other technical means to improve. Development of specific surface area is higher than carbon material of silicon material can improve the battery voltage. In addition, using lithium iron silicate instead of lithium iron phosphate can reduce cost, reduce the pollution of the environment. Considering the lithium. Sulfur and high than oxygen lithium battery can cause the great interest of researchers both at home and abroad. Waste lithium ion battery recycling method has written before, you can click on the link to see, but several problems existing in the current processing: ( 1) The classification of lithium ion batteries and recycling. Different types of lithium ion batteries with different material properties, this not only is the work of battery recycling enterprise, needs to be carried out effective policies and regulations, and help enterprises, guide people to the collection and classification of the battery. ( 2) Lithium ion battery recycling is limited to recycling of precious metals. High cost of recycling of metals, discarding the electrolyte and anode material, cause secondary pollution, the lack of the whole battery recycling system; ( 3) The recycling process still exist the problems of high cost, serious second pollution. To solve above problems, the lithium ion battery recycling needs not only in the process of optimization and improvement, also need to build a large-scale, comprehensive recovery process, a more pressing need to establish a system recovery system. In this regard, the state should make effective policies and regulations, the lithium ion battery manufacturers in China to scale, low cost, low secondary pollution in the direction of development. In addition, for the emergence of new products, we should plan ahead, recycling the basis of the research work.
