Waste ternary lithium battery cathode material recycling equipment

Our company Shaanxi Chengda Industrial Furnace Manufacturing Co., LTD. In the context of the dual carbon goal, with the country vigorously develop new energy vehicles, lithium batteries as a power source of new energy vehicles have been more widely used! . It is predicted that the number of electric vehicles on the road worldwide will reach 253 million by 2030. At the same time, the demand for power lithium-ion batteries will reach 2,800 to 3,000 GW.h, and the life of lithium-ion batteries is 3 to 10 years (1), so in the next 10 years, the number of used lithium batteries will show growth, which will bring new problems and challenges to environmental protection, human health and economic development. Therefore, how to recycle waste lithium batteries as green resources has become a hot topic in the whole society, especially the recycling of positive electrode materials with high added value.

Ternary lithium battery regeneration process
Wet gold leaching regeneration refers to the use of positive leaching liquid as raw material, by adding appropriate reagents to adjust the leaching liquid o and different metal ion concentration ratio to regenerate the synthesis of positive electrode materials, maximize the comprehensive recovery efficiency of metal, to achieve a closed cycle of recovery process. The advantage of wet regeneration is that the separation steps such as extraction, precipitation and so on are avoided after the dry process, which directly realizes the recycling of positive electrode materials. At the same time, the simple and effective process flow makes the wet regeneration has the value of popularization in industrial production. At present, the two most commonly used regeneration methods are co-precipitatin method and sol-gel method.
