The recycling process of the power lithium-ion battery is currently important for power lithium-ion battery manufacturers using electric vehicle manufacturers' sales networks, recycling waste batteries in reverse logistics. Consumers pay the scrapped battery back to the nearby electric vehicle sales service outlets, according to the cooperation agreement of battery manufacturers and electric vehicles, electric vehicles producers to the battery production company, and specialized recycling Battery manufacturers can continue to utilize recycled metal materials. The recycling of the power lithium-ion battery can be divided into two cyclic processes: first is the ladder utilization, important for battery capacity reduction makes the battery normally operate normally, but the battery itself is not scrapped, can still continue to use in other ways, for example For power storage; secondly is dismantling recovery, important for battery capacity loss, so that the battery cannot continue to use, only the battery is resourcefully processed, recovering the use of value regeneration resources.

Under policies, interests, responsibilities, etc., more and more related companies have begun to launch a lithium-ion battery recycling. In addition to the Shenzhen Greenmei, Wu Feng Lithium Industry, etc.

As the earliest group of new energy vehicles, BYD has begun to work with dynamic lithium-ion battery recycling work at the beginning of the new energy vehicle. At present, the channels of the BYD battery are important to entrust authorized dealers to recycle the waste dynamic lithium-ion batteries. When there is customer requirements or scrapped vehicles to replace the power lithium-ion battery, the dealer will take the power lithium-ion battery from the vehicle body, and Transportation to BYD Bao Long Factory for preliminary testing.

If the waste battery can be reused and continued, the waste battery will further test in Baolong Factory, which will continue to apply in the field of home energy storage or base station alternate power supply in the future. If the battery is unable to use, the BYD Bao Long Fact will transport the battery to the relevant departments of Huizhou Materials Factory. Dissolve, purified, reaction (due to the reaction before lithium iron phosphate formation, the use of the acid iron phosphate ion battery with wet recovery, the recovery effect is better).

In addition, another important component of the power lithium ion battery will also be recovered, and the dissolution method is collected, while the volatilized partial electrolyte light degradation is performed by the exhaust emission system, degrades into normal gas after discharging. As for the material such as the battery housing, it is also possible to carry out secondary utilization. For example, BYD dynamic lithium-ion battery has a relatively sound process system, high recovery efficiency.

In addition, BYD and Greenmei reached cooperation in September 2015, the most important part of the content of both parties is the circulation recycling of the waste product. Greenmei and BYD work together to build a circulating system for "Material Regeneration - Battery Renewability - New Energy Automobile Manufacturing - Dynamic Lithium Ion Battery Recycling". BYD is the largest car power lithium-ion battery manufacturer in China, and Green Mei is a domestic lithium-ion battery recycling leader company.

The two jointly established a leading position in the field of dynamic lithium-ion battery gradient utilization and recycling. Waterma Wartma In 2012, the route, method, method, method using the retired electric vehicle power lithium-ion battery in 2012, and built a 3MW phosphate ion battery energy storage power station. Raoders of waste power storage batteries laid the foundation.

At present, Watma has passed the declaration of Shenzhen Municipal Large-capacity Energy Stations Construction and Demonstration Applications, and the secondary use of two retired dynamic lithium-ion batteries, which is to test the decommissioned dynamic lithium ion battery, and there is a ladder utilization Value battery is used for energy storage power stations and mobile trimers, and cannot be used to decompose materials and regenerate, prevent environmental pollution. Currently recycled and ladder use to process 200MWH retired dynamic lithium-ion batteries. In addition to the development of the energy storage power station, Watma has also successfully developed 1200kwh, 750kwh, 640kWh mobile filling tram (used for electric vehicles, energy storage capacity, etc.

). In the future, it is considered to use waste dynamic lithium-ion batteries to mobile supplementary vehicles, and further explore the application of waste power lithium ion batteries in the energy storage system. In the lithium-ion battery recovery link, Watma adopts the multi-element component ratio to formulation reduction technology through the company's original "directional cycle" technology, the world's leading "reverse product positioning design" technology, supplemented by the formulation reduction technology to heat the synthetic solution And the power pH regulation, realize the "directional circulation" from the waste battery to the battery material, thereby organically integrating the battery from manufacturing and consumption to recycling throughout the circulation.

Guoxuan Gaoke Guoxuan Gaoke began the recycling of power lithium-ion batteries in 2012. In 2012, Guoxuan's high-tech made 1.3MW pure electricity and 4.

4MW container-type pure electric ladder utilization project. At present, Guoxuan HKU is developing battery recycling and ladder utilization related technologies and markets, which is about to launch a 12,000 AH battery recovery line, dynamic lithium-ion battery dismantling, metal and powder separation, powder treatment Waiting for it inside. According to the planning of Guoxuan's high-class, 2017, the sales scale of Guoxuan high-tech storage market is about 1 billion yuan, and will build a battery dismantling resource recycling line, day processing of 2000 battery.

In addition to the construction of the recycling system, CATL has cooperated with Hunan Bangpu, which is qualified to materials recovery, and the material is classified, dismantled, and materials. Recycle. Generally speaking, after the power lithium-ion battery is used, CATL will use very low cost to modify the energy storage.

Waiting for the battery to recover the battery after using it. In terms of energy storage, CATL invests in the Qinghai Xining investment plant, project plan investment of 7.5 billion yuan, covering an area of ​​20,000 mu, is an important part of the R & D, manufacturing, sales, supply of energy storage lithium-ion batteries, and supplies to the network.

Type and grid-wide energy storage products. In the field of energy storage, it has undertaken large energy storage projects of some key customers. When the total annual project has exceeded 40 megawatts, it will also deepen the relationship with provincial and area cooperative relations with domestic renewable energy power generation.

China Aviation lithium battery in terms of battery recycling, China Aviation lithium electricity has domestic first phosphate-based lithium-ion battery recovery production line. The demonstration line can maximize the valuable material in the lithium-powered lithium ion battery, wherein the copper aluminum metal recovery is as high as 98%, and the positive electrode material recovery exceeds 90%. After the battery is recovered, it will be placed in the battery area to be discharged, and the engineer is preliminary evaluation, understand the performance state of the current battery.

For the retired power lithium ion battery first test, filter out a better battery module or a monomer battery, divide the level according to certain rules, then carry out steps. After a part of the battery module is re-combined, it will be applied to motor boat applications, communication energy storage applications, spare power applications, agricultural machinery and other fields. About the battery monomer that is not reused again, the discharge treatment and further dismantling are performed, and the internal partial sections are classified and recovered.
