What are the problems of waste lithium battery recycling?

Used batteries contain a large amount of nickel, cobalt, manganese and other metals, which have a high recycling value. However, if they do not get timely solution, they will cause great harm to their bodies. Waste lithium-ion battery pack has the characteristics of large size, high power and special material. Under certain temperature, humidity and poor contact, they are likely to spontaneously combust or explode. In addition, unreasonable disassembly and installation may also cause electrolyte leakage, short circuit, and even fire.

It is reported that at present, there are two main methods of recycling used lithium-ion batteries: one is phased use, which means that the used battery continues to be used as a power source in areas such as electrical energy storage and low-speed electric vehicles; the second is to disassemble and reuse the battery that can no longer be used for recycling purposes. Some experts say that the gradual use is only one of the links, and the end-of-life lithium batteries will eventually be dismantled.

Obviously, no matter which aspect to consider, a lithium battery recycling company in improving its decomposition technology is a must. However, the industry also said that China's electronic information industry is still in its infancy, the core technology of each link is not fully mature, facing greater challenges in technology, equipment and other aspects.

The recycling of various types of batteries makes it difficult to automate the dismantling process, thus affecting the efficiency. Some experts believe that the recycling of lithium-ion batteries faces many constraints due to the complexity of their composition, as well as high technical barriers.

For the lithium-ion battery echelon use industry, assessment is the foundation, disassembly is the key, application is the lifeblood, and lithium-ion battery recycling assessment technology is an important basis for disassembly, but it is still not perfect, such as the lack of non-disassembly test methods for new energy vehicles, long assessment test time, low efficiency, etc.

The technical bottleneck of waste lithium batteries due to their residual value evaluation and rapid testing makes it difficult for recycling enterprises to obtain their recycling patterns and related data. Without relevant data support, it is very difficult to test used batteries in a short period of time.

The complexity of the eliminated lithium batteries is also a major challenge for the company. The complexity of end-of-life battery models, diverse structures and large technical gaps have resulted in higher costs and lower utilization rates for battery recycling and disassembly.

Various types of batteries are recycled, which makes automatic dismantling very difficult and thus leads to a decrease in work efficiency.

Enterprises and industry players demanded the establishment of a complete lithium system and the development of corresponding standards.

These problems have caused the recycling of waste lithium batteries in China is facing the dilemma of "higher cost of dismantling than direct disposal". However, some experts believe that one of the main reasons for the above problem is that there is no unified standard for lithium-ion batteries. With the rapid development of China's lithium battery recycling industry, there is an urgent need to develop new battery standards.

The recycling and disposal of waste power battery packs involves multiple links, involving physics, chemistry, materials science, engineering and other fields, the process is complex and time-consuming. Due to the different technical paths and dismantling methods adopted by each enterprise, it has resulted in poor technical communication within the industry and high technical costs.

Companies and industry players have called for a complete lithium system with corresponding standards. If there is a standard, then there must be a standard dismantling process. By establishing a standardized base, the investment costs of enterprises can also be reduced.

Then, how should a standard lithium-ion battery be defined? The design processing and recycling technology standard system for lithium-ion batteries should be improved as soon as possible, the standard design and dismantling specifications for lithium-ion batteries should be increased, the promotion of mandatory standards should be strengthened, and the corresponding control standards should be formulated.
