There is no doubt that we are the number one company in the world for lithium-ion battery shipments. However, the fact that lithium-ion batteries are being produced means that there are many more products that may become obsolete after this cycle is over. Since there are ways to recycle refrigerators, air conditioners, cell phones and other household appliances, can lithium-ion batteries be recycled on the same scale as these household appliances?

Lithium Recycling Market Size

After the DOD cycle, lithium batteries should be recycled just like household appliances. Although lithium batteries are known for being economical and environmentally friendly, they also have hazardous substances. If the previous landfill or incineration method is still used, it is bound to cause serious pollution to the atmosphere and soil, so there is an urgent need to improve the recycling system.

As of the end of 2017,Lithium battery recycling China's enterprises to carry out the cumulative promotion and development of new energy as a car more than 1.8 million vehicles, assembly work power battery about 86.9 GWh, after 2018 China's new energy as well as the main power battery of the car will enter into a large-scale decommissioning, it is expected that the cumulative total of more than 400,000 tons in 2022, the compound rate of increase of 70%. It is expected that the company's future we three years lithium-ion batteries can be recycled effective market will show economic rapid rising trend, to 2020 market demand is expected to exceed 15.6 billion yuan, compound annual growth rate of 41%.

Lithium battery is a chemical energy and electrical energy conversion of energy. The chemical reaction always occurs in the battery, and the side reaction between the anode and electrolyte is an important limiting factor in the cycle life of the battery. The average lifespan of consumer-grade batteries is 3 to 5 years, and the decommissioning cycle is generally judged based on the number of cycles, which is about 5 years. Power lithium batteries are used in new energy vehicles, and their lifespan depends on the charging frequency. The defense cycle for operating vehicles is 7 times per week, and for home use it is usually 1 time per week, and by 2025, lithium-ion battery waste is expected to reach 150 gigawatts.

Recycling process for waste lithium-ion batteries

Waste lithium battery anode material cut into small pieces, easy to anode copper foil on the carbon powder and acetylene crushed.

2. Put the plug plate under the crusher rotor, select the plug through the aperture, labeling machine leave the small one, continue to crush the big one repeatedly, and so on and so forth.

3. Falling into the crushing of screening technology equipment as well as particles can be used to use the size difference between these particles and shape difference by vibration for the screening process to achieve the separation of metallic copper and non-metallic carbon powder and acetylene black powder after hammer vibration stripping.

How to recycle lithium-ion batteries

First, the study of battery standardization, the implementation of traceability system.

Strengthen the power lithium-ion battery in the structural design,battery production line connection mode, process technology and comprehensive installation of standardization research, and as soon as possible to develop a mandatory coding standard for power lithium batteries, traceability system and new energy automobile product bulletin management system is connected to ensure that the record of battery life cycle information, in order to improve the convenience and accuracy of the test and evaluation.

Second, increase the research and development of key battery recycling technologies.

Increase the dismantling, reorganization, testing and life prediction of waste lithium-ion batteries and other key information technology companies to research and study, to improve the maturity of its technological development and the safety of the production and management process. At the same time, improve as well as battery dismantling, reorganization and recycling processing technology automation level and recycling efficiency, so that the power lithium-ion battery recycling and reuse aspects of China's economic and social feasibility and safety.
