Talking about the recycling value of lithium batteries

In recent years, lithium batteries have been accepted as a new type of energy storage method. At present, a large number of lithium batteries are used in travel tools and electronic equipment. The recycling of lithium batteries is imminent. Energy storage electrical lithium battery manufacturers attach great importance to lithium battery recycling. Regarding the usefulness of waste lithium batteries, we know that cobalt, lithium, copper and plastics in waste lithium batteries are precious resources with extremely high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. In order to alleviate the increasingly serious resource shortage and environmental pollution problems caused by the rapid economic development, it has become a global consensus to realize full-component recycling of waste lithium batteries. 1. Lithium battery power demand continues to rise. The use of lead-acid batteries as power in low-speed electric vehicles is largely due to the cost advantages of lead-acid batteries. Lead-acid batteries are relatively mature, stable and safe. However, due to the huge environmental pollution risk of lead-acid batteries and the continuous development of lithium battery technology, as well as the advantages of lithium batteries in terms of capacity and service life, lithium batteries as power will become the development trend of low-speed electric vehicles. It is foreseeable that more and more used lithium batteries will be received in the repair workshop in the future. 2. Waste lithium batteries have a strong recycling value. The anode, cathode, diaphragm, electrolyte and other materials contain a large amount of precious metals. The cathode materials of different power lithium batteries contain different precious metals, among which the most potential metals are cobalt, lithium and nickel. For example, the uniform content of lithium in a ternary battery is 1.9%, nickel is 12.1%, and cobalt is 2.3%. In addition, the proportions of copper and aluminum have reached 13.3% and 12.7% respectively, which have high recycling value. At present, some companies have begun to collect lithium batteries for a fee. 3. Improper solutions to waste lithium batteries will threaten the environment and health. Although lithium batteries do not contain mercury, cadmium, lead and other toxic heavy metals, they can also cause environmental pollution. For example, once the electrode material enters the environment, metal ions in the positive electrode of the battery, carbon dust in the negative electrode, strong alkali and heavy metal ions in the electrolyte may cause heavy environmental pollution, including increasing the pH value of the soil. If improperly solved, toxic gases may be generated. . Therefore, the solution of waste lithium batteries can not only bring economic benefits, but also contribute to the sustainable development of environmental protection and social economy.
