What are the different battery recycling methods?

As lithium batteries in the market accounted for a growing proportion of the recycling of used lithium batteries are also constantly innovating, the current international and domestic recycling of lithium batteries are mainly: pyrotechnic, wet and mechanical separation method, mechanical separation method is mainly through the lithium battery recycling equipment.

1 Individual thermal recycling and wet recycling is low automation and produces large pollution, high temperature smelting and long time blistering will make the valuable metals in the waste battery can not be maximized recovery, the recovery efficiency is very low.

2 The second is the combination of fire method and wet method. Its workflow is to put the used batteries into the smelting furnace with the temperature close to 1000 degrees Celsius by fire method, through the high temperature, the liquid and organic matter in the used batteries will finish decomposition, leaving the alloy. Next is the wet process, which utilizes the chemical reaction of acid and alkali precipitation to separate the valuable metals in the alloy. The advantages of this method are: multiple types of batteries can be processed at the same time, and the high temperature reduces the toxicity of the batteries. The disadvantages are: the operation process will produce a large amount of pollution, no timely and effective treatment, low recovery rate of lithium, easy to evaporate at high temperatures.

3 Mechanical recycling method - through the lithium battery recycling equipment recycling treatment of waste batteries. The workflow of this method is to crush the discharged lithium batteries into small materials first, dry the materials through the low-temperature drying oven, and then carry out multiple sorting and crushing of the materials, respectively, to screen out the black mass, copper and aluminum and other metals. At the same time, the lithium battery recycling equipment has supporting environmental protection facilities, such as spray tower, light oxygen, activated carbon, etc., the equipment operation process generated by the exhaust gas, dust, etc. will be processed through the environmental protection equipment and then discharged. Lithium battery recycling equipment can not only deal with many types of batteries at the same time, for example, cylindrical batteries, soft pack batteries, hard shell batteries, etc., and in a high degree of automation, with little manual involvement. In terms of recycling efficiency, multiple sorting and crushing, so that the purity of the recycling is enhanced and the value is high. So it is the most effective way to recycle waste lithium batteries through lithium battery recycling equipment.
