With more people using electronic products and new energy vehicles, the consumption of lithium batteries is also increasing. However, the amount of power battery recycling on the market has not reached the "small peak". At present, waste lithium batteries are commonly treated together with domestic garbage by landfilling, incineration, composting and other methods. The recycling work is large and urgent.
Although lithium-ion batteries for sale do not contain mercury, cadmium, lead, and other toxic heavy metal elements, they can also cause environmental pollution. For example, once the electrode material enters the environment, the metal ions of the battery cathode, the carbonaceous dust of the battery anode, the strong alkali and heavy metal ions in the electrolyte may cause heavy environmental pollution, including increasing the pH of the soil, toxic gases may be produced if treat improperly. In addition, the metal and electrolyte contained in lithium batteries can harm human health. For example, cobalt may cause intestinal disorders, deafness, myocardial ischemia and so on. Therefore, disposing of waste lithium batteries can not only bring economic benefits but also contribute to environmental protection and sustainable social and economic development.
1. Batteries that conform to the degree of energy attenuation take echelon utilization (used in the field of energy storage or low-speed electric vehicles), such as lithium iron phosphate batteries and ternary batteries.
2. Disassemble the batteries without echelon utilization value, and recover the nickel, cobalt, manganese, lithium, and other materials, such as digital batteries and some ternary batteries. In the field of battery recycling, especially the field of power battery recycling, the scale for echelon utilization is much lower than the scale of recycling and dismantling.
1) Lithium battery recycling faces unprecedented opportunities.
2)The secondary utilization of lithium batteries is a global trend.
