Specialized treatment and recycling enterprises have advantages in lithium battery recovery

Compared with lithium battery producers, specialized treatment and recycling enterprises have many advantages in the field of recycling, especially in specialized treatment technologies and environmental protection support. Accumulated a wealth of recycling experience and a complete team of talents including lead batteries, nickel-metal hydride batteries, and lithium batteries, and has the expertise to use wet and dry methods to deal with different types and models of used lithium batteries. At the same time, specialized treatment and recycling enterprises have obvious advantages in providing comprehensive environmental protection solutions. Most enterprises are equipped with complete secondary pollution treatment facilities, and various types of emissions meet environmental protection standards. In addition, some enterprises already have relevant waste treatment qualifications, such as hazardous waste operating licenses.

In order to improve the economic recovery of power cells, the state stipulates in the "Standard Conditions for the Comprehensive Utilization of New Energy Vehicle Power Batteries" that under the conditions of wet smelting, the comprehensive recovery rate of nickel, cobalt, and manganese should not be less than 98 %; The comprehensive recovery rate of nickel and rare earth should not be less than 97 %. The domestic leading lithium power recycling company, Bonp Group, mainly uses wet method technology, and the comprehensive recovery rate of nickel, cobalt, and manganese has approached or reached the requirements of the "standard conditions"; Taking into account that the source of used lithium batteries is not only a "high-taste" power battery, the high recovery rate of the Bond Group has proved the technical strength of the specialized processing companies it represents.

Specialized processing and recycling companies attach great importance to the construction of R&D teams. Domestic professional recycling companies such as Green America, Bond Group, and Fangyuan Environmental Protection have cooperated with strong metallurgical schools such as Tsinghua University, Zhongnan University, and Beijing University of Technology to carry out "production and research" and actively introduce academicians., professors and other talents. In the field of deep tillage recycling for many years, specialized treatment and recycling enterprises have obvious advantages in the recovery technology of dry and wet methods and have many patents. With the outbreak of the old power battery market, specialized processing enterprises R&D reserves, scale effect and other advantages will be highlighted.

The secondary pollution in power cell recycling is a huge challenge for enterprises. Extractive agents used in recycling, exhaust gas generated during recycling, and residues after metal extraction will cause pollution to the environment. The Environmental Protection facilities of specialized treatment and recycling enterprises are complete, and a more mature treatment system has been established in the prevention and control of secondary pollution. Take greenmail as an example, the company will recycle the metal residue and coal gangue, shale, etc. for mixing, roasting, pressing into environmental protection bricks to maximize the recycling of resources; At the same time, the results in liquid pollution treatment and water ecological restoration are obvious, with a complete set of environmental ecological restoration system.

At present, only waste lithium batteries are recycled, and there are no relevant qualification requirements. However, waste lithium batteries contain heavy metal elements such as nickel, cobalt, and manganese. Further treatment of waste battery components containing certain heavy metals(such as nickel) requires a hazardous waste operating license; In addition, the electrolyte contains lithium hexafluorophosphate, which is prone to release hydrofluoric acid in water and is harmful to the human body and the environment. In May 2017, the state issued the "Guidelines for the Dismantling of Vehicle Power Batteries for Recycling and Utilization", which put forward some specific requirements for the recycling qualifications of power batteries. In the future, with the gradual landing of relevant policies, we expect that the qualification related to battery recycling such as hazardous waste management licenses will become an important asset and competition barrier for specialized treatment enterprises.
