How to dispose of lithium batteries properly?

Lithium batteries are mainly composed of positive electrode, negative electrode, separator and electrolyte. After the battery is used, these components still contain a large amount of recyclable materials, such as copper, aluminum, cobalt, lithium, etc. 

However, how to properly dispose of used batteries has become a core issue in lithium battery recycling. As a professional lithium battery recycling machine manufacturer, Henan Doing will provide you with efficient and environmental friendly lithium battery recycling methods and related equipment. Next, let's learn about the disposal process of lithium battery, taking Doing’s lithium battery recycling machine as an example.

Used battery collection:

The first step in lithium battery recycling is collecting used batteries. This includes collecting used batteries from sources such as discarded electronic equipment, electric vehicles, tools and more. Establishing an effective recycling network can promptly recycle and dispose of used lithium batteries.

Pretreatment - discharge treatment:

Soak the used lithium battery in a sodium chloride solution to short-circuit the positive and negative electrodes of the battery, thereby completely discharging the battery and releasing excess battery energy. This can avoid the risk of short circuit and fire during the crushing and sorting process.

Crushing and screening:

The discharged used lithium batteries are sent to the double-shaft for shredding. The fragments are then further broken up. The crushed pieces of lithium battery enters magnetic separator, which can separate the iron. The broken particles fall into screening equipment (such as vibrating screens, air separator, electronic separator etc.), and the size and shape differences between particles are used to separate copper, aluminum and black mass.

Carbonization:

In lithium battery recycling, carbonization process is an important part. Carbonization is the process of converting organic matter into carbon-like substances by heating battery residue in a low-oxygen or anaerobic environment. Carbonization helps convert battery residue into high-purity carbon materials that can be reused in battery production or other industrial applications.

Waste Disposal:

Environmental protection is also a very important consideration throughout the disposal of lithium batteries. The waste and by-products generated during the disposal of used lithium batteries need to be handled and disposed of safely. The exhaust gas treatment of our lithium battery recycling equipment mainly uses a spray tower system, an activated carbon system and a UV photooxygen catalytic system. The combination of cyclone dust collector and pulse dust collector can collect the dust generated during the entire process and make the site clean.

Doing lithium battery recycling machine can process different types of used lithium batteries to separate copper, aluminum, diaphragm and black mass, greatly improving the flexibility and efficiency of lithium battery disposal. In addition, lithium battery recycling machine is equipped with an intelligent negative pressure system, a remote operating system and an advanced waste disposal system, making the entire disposal process efficient, highly controllable and environmentally friendly.
