Discarded batteries contain nickel, cobalt, manganese, and other elements, making them valuable for recycling. However, if not disposed of promptly, they pose significant safety hazards. Waste lithium-ion battery packs are large, high-powered, and made of special materials. Under certain temperature, humidity, and poor contact conditions, they are prone to spontaneous combustion or explosion, similar to other types of batteries. Furthermore, improper disassembly can lead to electrolyte leakage, short circuits, and fires.
It is understood that there are currently two main methods for recycling used lithium-ion batteries: one is phased use, which allows used batteries to continue to be used as power sources in areas such as energy storage and low-speed electric vehicles; the other is dismantling and recycling batteries that can no longer be used. Experts point out that tiered utilization is only one link in the recycling process, and the final destination for retired lithium-ion batteries still needs to be dismantled.
Clearly, from any perspective, lithium-ion battery recycling companies possess essential skills for improving lithium-ion battery dismantling capabilities. However, industry experts point out that because the industry is still in its early stages of development, key technologies at each stage are not yet mature, leading to numerous challenges in technology and equipment.
Recycling different types of batteries presents significant challenges to automated disassembly, reducing work efficiency.
Industry insiders point out that due to the complex composition of lithium-ion batteries, recycling faces many limitations and high technical barriers.
For industries using lithium-ion batteries, assessment is fundamental, disassembly is crucial, and application is the lifeline. Lithium-ion battery recycling assessment technology, as an important basis for disassembly, is still immature. For example, new energy vehicles lack non-disassembly testing methods, and assessment and testing are time-consuming and inefficient.
Bottlenecks exist in technologies such as residual value assessment and rapid detection of end-of-life lithium-ion batteries, making it difficult for recycling companies to obtain battery cycle models and lithium-ion battery management data. Without supporting data, recycling companies struggle to quickly detect end-of-life batteries.
The complexity of the retired lithium-ion battery family has also become a challenge for the company. The complex models, diverse structures, and significant technological gaps of retired batteries directly lead to high battery recycling and dismantling costs and low utilization rates.
Different types of batteries have been recycled, which has made dismantling automation very difficult and reduced work efficiency.
Companies and industry experts are calling for the development of lithium-ion battery systems and standards.
The aforementioned problems have directly led to the awkward situation in the recycling of used lithium-ion batteries: dismantling costs are higher than the cost of direct disposal. However, experts point out that a major reason for these problems is the lack of a unified lithium-ion battery standard. As the lithium-ion battery recycling industry continues to develop, the need for introducing battery standards is growing.
The entire process of recycling and processing used lithium-ion battery packs involves multiple steps and interdisciplinary fields such as physics, chemistry, materials science, and engineering, making it technically complex and lengthy. Different companies choose different technical approaches and dismantling methods, leading to poor technology flow within the industry and high technical costs.
Companies and industry experts are calling for the establishment of lithium-ion battery systems and standards, as the development direction of lithium-ion batteries undoubtedly determines the development direction of their reprocessing industry. If there is a standard for battery processing, then disassembly will certainly form a unified standard. With a standardized foundation, companies can also reduce investment costs.
So, what are the specific requirements for the standardization of lithium-ion batteries? We need to improve the technical standard system for the design, processing, and recycling of lithium-ion batteries as soon as possible, add new standard design and disassembly specifications for lithium-ion batteries, increase the promotion of mandatory standards, and formulate relevant control standards.
