The lithium battery is mainly composed of a shell, a positive electrode, a negative electrode, an electrolyte and a diaphragm. The positive electrode is composed of lithium cobalt oxide powder coated with polyvinylidene fluoride (PVDF) on both sides of the aluminum foil collector, which has a bonding effect; the structure of the negative electrode is similar to that of the positive electrode, and is composed of carbon powder bonded on both sides of the copper foil collector. Lithium-ion batteries have the advantages of high voltage, large specific capacity, long service life, and no memory effect. Since commercialization, lithium battery recycling has rapidly occupied the power market of portable electronic devices, and the output has increased year by year.

The service life of lithium batteries is about 2 years. If the scrapped lithium battery is not recycled properly, the heavy metals such as lithium hexafluorophosphate, carbonate organic matter, cobalt, copper and so on will inevitably pose a potential pollution threat to the environment. On the other hand, cobalt, lithium, copper and plastics in waste lithium batteries are valuable resources with high recycling value. Therefore, the scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits.

Principle of lithium battery recycling equipment: lithium battery recycling equipment uses crushing equipment to tear up the raw material shell, crush it to less than 10mm by coarse crusher, then enter the particle crusher for stripping and crushing, and then enter the micro-powder classifier for separation and treatment. The tail ash is collected by the post-cyclone separator and the pulse dust collector.

Lithium battery recovery According to the lithium battery positive and negative structure and its constituent materials copper, carbon powder material characteristics, waste lithium battery negative plate treatment equipment using hammering crushing combination process, vibration screening and air separation separation recovery of waste lithium battery negative component materials. The whole set of equipment runs under negative pressure, no dust leakage, and the metal separation effect is good.

Performance characteristics of lithium battery recycling equipment:

1. For the recycling of waste lithium batteries, it has played a greater economic benefit;

2. The recovery and separation technology of lithium battery recovery equipment improves the recovery efficiency of lithium battery and realizes automatic separation technology;

3. Lithium battery recycling equipment can recycle all kinds of waste lithium batteries, including soft bags, plastic shells, hard shells, steel shells, lithium batteries, etc.

In the past, the disposal of used lithium batteries has been a problem. Improper handling may cause harm to the environment and human body. Now, the use of lithium battery recycling equipment effectively solves this problem. Its treatment will not cause harm to the environment, and copper and aluminum metal materials will be recycled through the equipment. The precious metals contained in waste lithium batteries can be reused, which greatly reduces the consumption of energy materials and realizes the virtuous cycle and development of lithium battery resources. Lithium battery recycling equipment is in line with the current development trend of environmental protection. With the continuous growth of the new energy market, the future market development space is huge.
