usine de recyclage de batteries au lithium

In recent years, with the explosive growth of the electric vehicle and energy storage markets, demand for lithium batteries has surged, but this has also led to increasingly severe problems with the disposal of used batteries. Currently, the global lithium battery recycling rate remains less than 10%, leaving a large number of used batteries landfilled or improperly disposed of, resulting in resource waste and environmental pollution. Therefore, establishing an efficient lithium battery recycling system is urgent.

Current Status of Lithium Battery Recycling

Currently, lithium battery recycling is primarily focused on ternary lithium batteries and lithium iron phosphate batteries. European and American countries are promoting recycling through legislation, while China, the world's largest lithium battery market, is rapidly developing its recycling network. However, technical bottlenecks (such as low metal separation purity) and cost issues remain challenges for the industry.

Lithium Battery Disposal Methods

The treatment of used lithium batteries primarily involves cascade reuse and disassembly and recycling. Mildly degraded batteries can be downgraded for use in energy storage or low-speed electric vehicles. Completely scrapped batteries are then processed through crushing, sorting, and hydrometallurgical processes to extract valuable metals such as lithium, cobalt, and nickel. Wet recycling has become mainstream due to its high recovery rate (over 95%), but pyrometallurgical recycling still has applications in some areas.

Recycling Process

Collection and Transportation: Used batteries are collected and transported through partnering automakers or recycling centers to ensure safe transportation.

Discharge and Disassembly: After complete discharge, the battery casing and electrode materials are mechanically separated.

Material Separation: After crushing, metals, plastics, and electrolyte are separated physically or chemically.

Purification and Reuse: Leaching, precipitation, and other processes are used to extract high-purity metals for re-production.

Recycling Plant Location and Plan

The ideal recycling plant should be located near battery production centers or major cities to reduce logistics costs. The plan should include:

Automated production lines: Improve sorting efficiency and reduce manual intervention.

Environmentally friendly design: Equipped with an exhaust gas and wastewater treatment system that meets green standards.

Partnership Model: Build a closed-loop supply chain with automakers and battery manufacturers to ensure a stable supply chain.

Lithium battery recycling is not only an environmental imperative but also a resource strategy. With technological advancements and policy support, large-scale, intelligent recycling plants will become an industry trend.
