The Recycling of Used Lithium Batteries The low molecular organic matter lithium hexafluorophosphate, heavy metals and plastics in lithium batteries can bring serious harm to the natural environment and human health. If the waste batteries can be recycled, not only can save a lot of natural mineral resources, but also eliminate the various hazards caused by waste batteries. Therefore, in recent years, the recycling of used lithium-ion batteries has become a key research area for various research institutes. The recycling of used lithium batteries is mainly to extract the relatively high value of non-ferrous heavy metals such as cobalt and lithium in lithium batteries. As the positive material in the lithium battery is complex, it may lead to the separation and extraction process of the metal material purity is not high. And lithium battery recycling processing equipment is good for sorting processing, which can improve the recovery rate of valuable metals. Used lithium batteries are physically recycled, the equipment is fast and efficient, and does not cause any environmental pollution. present disposal lithium batteries need lithium battery recycling processing equipment, ternary lithium battery recycling processing equipment, used lithium battery positive and negative electrodes processing equipment, lithium iron phosphate battery recycling processing equipment, lithium battery crushing and recycling equipment, these devices correspond to different lithium batteries for processing.

3 in 1 Pouch Cell Machine Usually, we need 3 machines for pouch cell top-side sealing, electrolyte dissusion, and vacuum pre-sealing. TOB, we designed 3 in 1 machine TOB-YF200-JZ that can combine these three functions. 1. The sealing head is soft type, when do top sealing, there are tabs between pouch, soft sealing head can get better sealing effect. 2. It's equipped with battery box, put batteries in the box and remove air from the electrolyte under vacuum, it’s suitable for all types of batteries to do vacuum standing process (especially soft bag battery and cylinder battery). 3. Tilted battery fixture plate design that revent leakage of electrolyte during pre-sealing. By the way, when do vacuum secondard sealing, you can manual puncture the air bag, and also use this machine do the vacuum secondard sealing. TOB, we are not only providing you high quality equipment, good service, but also professional technology. If you are interested in lithium ion battery, please contact us freely.
