How to dispose of old Li-ion batteries safely?

When Li-ion batteries reach the end of their lifespan, improper disposal or dismantling can lead to short circuits, leakage, or even fires. Furthermore, the chemical substances contained within the batteries, such as heavy metals and electrolytes, can cause long-term damage to soil and water sources if released into the environment. Therefore, safely handling old lithium-ion batteries is not only necessary to prevent safety risks but also a demonstration of environmental responsibility.

Key Steps for Safe Disposal of Li-ion Batteries:

1. Standardized Collection and Classification

Old lithium-ion batteries should be collected separately and not mixed with other waste. It is recommended to store them in corrosion-resistant, insulated containers and classify them according to battery type, specifications, and condition. Storage areas should be kept dry, well-ventilated, and away from high temperatures and sources of ignition.

In addition, when transporting scrap lithium batteries, ensure that the battery electrodes are wrapped in insulating material to prevent accidental short circuits. For bulk transportation, use packaging and specialized transport containers that meet safety standards to reduce the risks during the transportation of Li-ion batteries.

2. Entrust to Professional Institutions

Individuals or businesses should not disassemble used batteries themselves. The safest way is to hand over old lithium-ion batteries to qualified recycling institutions. These institutions possess professional battery recycling equipment and technology, enabling safe and efficient processing.

3. Resource Utilization

① Discharging old Li-ion batteries is an important pre-treatment step that reduces risks during subsequent disassembly. This step must be performed in a controlled environment.

② Li-ion batteries are disassembled using specialized equipment to separate components such as the casing, electrode materials, and diaphragm. This process should avoid manual disassembly to control safety risks.

③ The disassembled lithium batteries can be further separated and purified. Valuable materials in used lithium-ion batteries, such as lithium, cobalt, and nickel, can be extracted and used to produce new batteries or other products. This process reduces resource waste and lowers the environmental pressure of mining new materials.

As a manufacturer of Li-ion battery recycling machine, DOING continuously focuses on industry safety standards and technological advancements. We are committed to helping our customers achieve safer and more sustainable battery processing and recycling through equipment optimization, covering various stages including discharge, crushing, sorting, and material recovery.

DOING li-ion battery disposal recycling machine

For example, we use automated mechanical dismantling and recycling methods to separate materials from waste lithium-ion batteries, reducing the risk of direct contact. The entire battery recycling process design emphasizes airtightness and the control of exhaust gases and dust, minimizing the possibility of fire and pollution.

Besides, DOING lithium-ion battery recycling machine utilizes multi-stage crushing and fine sorting technologies (such as airflow separation, screening, and magnetic separation) to achieve efficient separation of black powder (containing lithium, cobalt, and nickel) and copper-aluminum foil, directly improving economic efficiency. The entire Li-ion battery processing flow employs an intelligent PLC control system to monitor and warn against critical parameters such as temperature, pressure, and oxygen concentration in real time, ensuring visualization and traceability throughout the entire process, guaranteeing safe, environmentally friendly, and stable operation.
