Battery Recycling & Reuse
As the popularity of electric vehicles grows, so does the number of spent lithium-ion batteries that once powered them. Industry analysts predict that by 2030 the number of used Li-ion batteries will reach two million tonnes per year worldwide.
Li-ion batteries are extremely flammable and sensitive to high temperature. Under heat, these battery packs tend to degrade much faster than they normally would; and if they fail, they could burst into flames and can cause fire and/or explosion hazards. The potential danger warrants expert care and handling.
However, EV batteries can still retain at least 70% of their original storage capacity as they reach end-of-life, which means they can be repurposed for “second life” energy storage. Innovative new processes can also be used to rapidly extract valuable materials from existing battery packs and change their chemistries to ensure both economic and environmental benefits of recycling.
How it works
Since 2018, Dunwell has initiated an EV battery collection and recycling program as part of its one-stop recycling service for the automotive industry. By establishing risk management protocols in consultation with manufacturers, recyclers and relevant experts, our collection procedures can effectively avoid battery breakdowns and thermal or mechanical damage during the transportation and disassembly process.
The recycled EV batteries are then dismantled into valuable metals and materials such as copper, cobalt, nickel and rare earth elements, and exported to overseas qualified operators for further treatment and reuse. Dunwell also collaborates with different experts to research more ways to realize the potential of used batteries.
The types of batteries we handle include:
- Primary batteries
- Lead-acid batteries
- Hybrid car batteries
- EV batteries (Li-ion)
- EV batteries (Ni-MH)
- Other rechargeable batteries
The entire collection and recycling process complies with the regulation of Waste Disposal Ordinance (Cap.354) of HKSAR.
