What is the proportion of lithium-ion battery recycling costs

As far as power lithium battery cells are concerned, they include positive electrode, negative electrode, diaphragm, and electrolyte. Because of its stable material structure and longer life span, lithium iron phosphate batteries may be more profitable in cascading use of energy storage. The ternary batteries used in passenger cars contain cobalt, lithium, nickel, copper, aluminum, etc., many of which are rare metals. One can imagine the huge profits hidden by their recycling. There are currently three recycling methods for lithium-ion battery costs. The first is that government departments cooperate with new energy vehicle companies to consume a part of used power batteries for energy storage or other purposes. The battery model and structure are more unified, and it is more convenient to use technical means to test battery performance and life. China Tower and Nanjing Jiangbei Energy Storage Power Station are the 'big brothers' in this field. The second is that car companies establish their own recycling system to recycle the decommissioned power batteries sold under their brands. Using technical means to use the battery ladder in other production equipment of its car factory, of course, completely scrapped batteries will be dismantled uniformly, and valuable metal substances and other materials will be recovered, which greatly saves the production cost of car companies. Volkswagen is already preparing to establish a battery factory in Germany. After completion, it will be able to process 1,200 tons of used car-grade lithium battery packs every year. The recycling rate is expected to reach 97% in the next ten years! The third type is a specialized battery recycling company. At present, there are only 5 recycling companies recognized by the state that meet industry standards. Because of the huge profits of recycling, many 'small workshops' recycle lithium batteries and conduct violent dismantling. The consequence of lack of professional means is that the recycled materials are rough, and the unprofessional treatment of battery electrolyte will cause environmental pollution. The power battery recycling market is huge, but this 'big cake' is not something that everyone can eat. It is necessary for people who can eat the cake to divide it up. This is the real use of the material. Fortum’s recycling of batteries uses a hydrometallurgical process. First, the batteries can be safely processed mechanically by separating plastic, aluminum and copper, and the separated materials are allowed to enter their respective recycling processes; then, the cobalt, manganese, nickel and Lithium is recycled and returned to the battery manufacturer for use in the production of new batteries. In addition, Fortum is still using batteries to test 'secondary' applications. After such batteries are no longer suitable for applications such as electric vehicles, they have been eliminated as stationary energy storage devices. In February of this year, Volkswagen announced that it had started a pilot project for a battery recycling plant in Salzgitter, Germany. The company stated that its long-term goal is to recycle 97% of the material in each battery. The Belgian company Umicore is currently able to recycle about 150,000 to 200,000 electric car batteries. In modern times, batteries can and are being recycled, but compared to recycling, it is still cheaper to produce new lithium and cobalt. China hopes to force electric vehicle manufacturers to recycle used batteries. In the summer of 2018, China launched a pilot program for recycling used electric vehicle batteries in 17 cities and regions.
