Since 2013, China has successively introduced various subsidy policies for new energy industries, and the new energy automobile manufacturing industry has also begun to enter the acceleration stage. However, the lithium iron phosphate battery can be used for 6 years and the ternary lithium battery can be used for 7 years. In other words, from 2020, new energy batteries will be gradually retired.

By 2030, 12 million tons of lithium-ion batteries will be decommissioned in the world, and the output value will reach 200 billion yuan. China will become one of the largest markets in the battery recycling industry. It is a mine that can be continuously developed by the new energy industry and a land that can be deeply cultivated by the environmental protection industry. A cell phone battery can pollute 1 square kilometer of land. Cobalt, manganese, nickel and other heavy metals cannot be degraded by themselves. For example, more than 500 micrograms will lead to manganese poisoning.

The weight of new energy batteries is thousands of times that of mobile phone batteries. Tesla Model 3 battery weighs 480KG, and Weilai automobile weighs more than 500 kg. If you throw it away at will, the pollution will be immeasurable. At this time, it is necessary to recover the lithium battery.

At present, there are two main methods for recycling waste batteries:

The first is echelon utilization;

The second is to recycle the battery metal directly;

The goal of new energy battery recycling is to achieve high recovery rate, reduce costs and reduce environmental pollution.
