With the continuous development of new energy vehicles, continue to popularize. The country also strongly advocates new energy today, lithium batteries are constantly being eliminated, lithium batteries when the service life of about 3-5 years, so the market for recycling used batteries is also growing. In the severe background of the shortage of metal resources. Used lithium battery recycling has also received strong support from the state, because the lithium battery recycling industry has broad prospects for development.
Waste lithium battery recycling process methods:
Dry method: the waste lithium battery by first shredding, and then broken up, so as to collect the plastic diaphragm, and then through the magnetic separator to extract the iron shell nickel strip, and then crushed, once sieved, the mixture in into the grinder under the summary, in the sieve, and then copper and aluminum separation. According to the specific waste battery to see whether it needs to be equipped with discharge equipment as well as discharge cycle box. According to the type of dry and wet degree of boredom to determine whether the need for low-temperature furnace. The whole set of recycling process to use to: lithium battery recycling processing equipment.
Wet metallurgy: lithium battery regeneration mainly contains three processes: extraction, electrowinning and electrodialysis. Extraction is the main use of organic dissolution and water for the reasonable distribution of organic compounds, so as to extract valuable metals in the solvent. The more important thing in this process is that the extractant can be directly mixed with the raw material in the de-extractor, and then circulate the pump to the organic phase extraction, the extractant can add acid solution or other substances for ion exchange with the valuable metal, so as to form a precipitation. This recovery process is more costly.
Electrodialysis is the separation of substances by means of a click reaction, in which the ions contained in the solution migrate to the electrodes by means of an electric field. In the process of electrodialysis to achieve the selective separation of ions, this recycling room ah is mainly through the waste lithium battery electrode applied DC voltage can make the electrode surface charged ions through the current into the electrode gap, and then through the membrane pore adsorption and ion exchange, so as to effectively remove the waste battery equivalent lithium metal and phosphorus for effective separation. Thus, the purpose of recycling is achieved.
From the perspective of ecological protection. The recycling of used power batteries is still a huge challenge to the ecology, and the amount of new energy vehicles in China has reached 100 million. Electronic technology products are being phased out one after another, and the demand for recycling of used lithium batteries continues to increase. Therefore, the lithium battery recycling industry has good prospects for development.
