Waste lithium batteries For ternary batteries, compared with lithium iron phosphate, its battery life is shorter. 80% of the cycle life of ternary material batteries is only 800-2000 times, and there are certain risks. It is not suitable for the use of energy storage power stations, communication base station backup power supplies and other complex cascade utilization areas. However, since ternary power lithium batteries contain rare metals such as nickel, cobalt and manganese, by disassembling and extracting lithium, cobalt, nickel, manganese, copper, aluminum, graphite, diaphragm and other materials, it can theoretically achieve an economic benefit of about 42,900 yuan per ton, which is economically feasible. Taking ternary 523 batteries as an example, the nickel, cobalt, manganese and lithium contents of ternary batteries per ton are about 96, 48, 32 and 19 kilograms. At present, the average recovery rate of nickel, cobalt and manganese in the market can reach more than 95%, and the recovery rate of lithium is about 70%. The market prices of metal lithium, cobalt, electrolytic nickel and electrolytic manganese are 900,000 yuan/ton, 480,000 yuan/ton, 100,000 yuan/ton and 17,000 yuan/ton respectively. The nickel sulfate, cobalt sulfate, manganese sulfate and other metal salts recycled from power lithium batteries can be produced sustainably to solve the problem of processing ternary precursors, with clear value-added space.
Finished product diagram of waste lithium batteries As for the use of waste lithium batteries, we know that cobalt, lithium, copper and plastic in waste lithium batteries are all valuable resources with great recycling value. Therefore, scientific and effective treatment and disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. Due to the increasingly serious resource shortage and environmental pollution problems caused by rapid economic development, it has become a consensus in the industry to realize the recycling of all components of waste lithium batteries. To recycle waste lithium batteries and make money, choose a set of production lines for disassembly and recycling equipment, as shown in the figure below:
Waste lithium battery disassembly and recycling equipment is the lithium battery recycling and disassembly equipment production line that collects scrapped power batteries, recycles nickel, cobalt, manganese, copper, aluminum, lithium and other metals in the battery through process technology, and then recycles these materials to manufacture power battery packs and apply them in new energy vehicles. When the power capacity drops below 40% of the initial capacity, it is generally selected to enter the dismantling and recycling stage. The disposal processes included in the application of lithium battery recycling and dismantling equipment include dismantling process, crushing process, pulverizing process, screening and sorting process and waste gas collection process.
