Waste lithium batteries are very troublesome to handle, and littering is very harmful to the environment. At present, the batteries for electric vehicles on the market mainly include traditional lead-acid batteries and emerging lithium batteries, but the recycling of lithium batteries is completely different.
If the discarded lithium batteries are not handled properly, the lithium hexafluoroate, carbonate organic compounds and heavy metals such as cobalt and copper contained in them will inevitably pose a potential pollution threat to the environment. On the other hand, cobalt, lithium, copper and plastics in waste lithium batteries are precious resources with high recycling value.
When the waste lithium pool is discarded as garbage and enters nature, the heavy metals in it cannot be biodegraded, causing serious pollution to the environment. According to statistics, a waste battery can permanently lose the value of 1 m2 of soil, and a button cell can pollute 600,000 liters of water.
