What are the current modes of lithium Battery recycling

At present, there are two recycling modes for batteries: one is cascade utilization, and the other is to disassemble and remake the raw materials for lithium batteries. In terms of incentive measures, the state will provide support for technology research and development, equipment import, and other aspects of cascade utilization and recycling enterprises within existing funding channels, encouraging enterprises to continuously improve their technological level, save resources, and protect the environment.

In terms of technology research and development, the state supports the research and development of recycling technologies and equipment related to power batteries, and encourages waste power battery recycling enterprises, cascade utilization enterprises, and recycling enterprises to continuously develop and promote new technologies. In terms of international cooperation, the state will encourage international exchanges and cooperation in the field of electric vehicle power Battery recycling recycling, support the joint formulation, coordination and unification of national standards, and support the construction of high-level demonstration projects.

Nowadays, there has been a significant breakthrough in the recycling technology of waste lithium-ion batteries, but the existing technology has high costs, complex operations, and can also cause secondary pollution. The existing recycling technology only focuses on the positive electrode material, which is only a simple separation and copper foil recycling for the negative electrode. Carbon negative electrode waste has not been effectively repaired and reused.

The project adapts to the industry development plan and relevant requirements, and has high feasibility. The completion of the research and development of key technologies of the intelligent production line for the comprehensive recovery of waste lithium batteries of new energy vehicles will greatly promote the recovery and utilization of lithium Battery recycling in automobiles. The development and layout of the industry chain will be improved. The recovery and treatment of waste lithium ion Battery recycling can not only reduce environmental pollution, but also achieve considerable economic benefits.

The complexity of waste batteries is high, and disassembly is inconvenient. The complexity of retired power batteries is high, including the complexity of manufacturing and design processes for different types of batteries, the form of series parallel grouping, service and usage time, and the diversity of application models and usage conditions. For example, there are different types of batteries, such as square, cylindrical, and soft packs, and their stacking and winding forms are also different. Due to different integration forms, the battery packs after grouping are also different.

These complexities make it inconvenient to recycle or disassemble Battery recycling. Therefore, in the case of low automation level at present, most processes are completed manually, and the skill level of workers may affect the yield of Battery recycling. At the same time, during manual disassembly, battery short circuit and leakage may lead to fire or explosion, which has potential safety hazards to people and property.

The recycling of lithium battery packs urgently requires the introduction of intelligent production line equipment throughout the entire process from warehousing to scrapping, from warehousing, dismantling battery packs, to cascade utilization or recycling, and conducting full lifecycle traceability management.
