All You Need to Know About EV Battery Recycling
As the electric vehicle (EV) market continues to surge, managing end-of-life (EOL) battery packs has become a pressing concern for manufacturers. Recycling these batteries not only reduces environmental impact but also secures critical raw materials for future production. At Infinitev, we are committed to exploring and implementing innovative recycling solutions to drive a sustainable circular economy. Here's a closer look at the evolving landscape of EV battery recycling.

Key Recycling Methods for EV Batteries
There are two commonly used recycling methods in pyrometallurgy and hydrometallurgy, with emerging technologies such as direct recycling in early-stage development.
-
Pyrometallurgical Recycling
Involving high-temperature smelting, this widely used method recovers metals like cobalt and nickel but often loses lithium in the process. -
Hydrometallurgical Recycling
This chemical leaching process efficiently extracts valuable metals such as lithium, cobalt, and nickel. -
Direct Recycling
An emerging technology that preserves the structure of cathode materials for reuse.
As you'd expect, each method has it's own advantages and challenges. Here are five common questions we get asked about these methods, and quick answers to allow a side by side:
| Question | Pyrometallurgy | Hydrometallurgy | Direct recycling |
|
1. How does this method work? |
High-temperature smelting to recover metals. |
Chemical leaching to extract valuable metals. |
Retains and reuses cathode materials with minimal processing. |
|
2. Which valuable materials are recovered? |
Cobalt and nickel; lithium is often lost. |
High recovery of lithium, cobalt, and nickel. |
Cathode materials (e.g., lithium, cobalt, nickel) remain intact. |
|
3. What are the associated costs? |
High; energy-intensive and costly environmental controls. |
Moderate; chemical handling required. |
Potentially low; still in R&D phase, needs scaling. |
|
4. How scalable is this method? |
Highly scalable but less sustainable. |
Scalable; widely adopted globally. |
Not yet scalable; promising for the future. |
|
5. What are the environmental impacts? |
High emissions due to energy use. |
Lower emissions; chemical waste must be managed. |
Lowest impact; minimal energy use and emissions. |
Addressing Key Industry Questions About EV Battery Recycling
Different scenarios will favour different recycling methodologies. Morever, frequently asked questions about EV battery recycling include these ones:
How do battery chemistries (NMC, LFP, solid-state) affect recycling methods?
Lithium Nickel Manganese Cobalt (NMC) batteries offer high recycling value due to valuable metals. Lithium Iron Phosphate (LFP) batteries, with fewer critical materials, are less profitable to recycle. Solid-state batteries will require new recycling technologies as they scale. Depending on the scale of operations, recycling can have a negative yield. That means it costs more to run the recycling process than the value of outputs that's generated. This is why reusing battery cells and components makes a lot of economic sense, in addition to being good for the environment.
What role do OEMs play in advancing battery recycling technology?
OEMs can design batteries for repairability and recyclability, invest in innovative recycling startups, and develop closed-loop systems to recover and reuse materials. Collaboration with remanufacturers and recyclers can improve recovery rates and reduce dependency on raw materials.
Are there regulations incentivising battery recycling innovation?
Yes. The EU Battery Regulation enforces recycling targets, the U.S. Inflation Reduction Act incentivises domestic recycling, and China mandates battery tracking and certified recycling partnerships. In Australia, the Association for the Battery Recycling Industry (ABRI) and Battery Stewardship Council (BSC) are exploring suitable incentive schemes, as is the Battery Industry Group (BIG) in New Zealand.
What are the risks associated with recycling EV batteries?
Risks include thermal runaway during transport, hazardous material handling, and supply chain bottlenecks. Implementing strict safety protocols and scaling infrastructure are essential to mitigate these risks. At Infinitev, we have extensive experience in decommissioning batteries so that they are safe to handle and transport, ready to be recycled.
What emerging technologies could improve battery recycling efficiency?
Innovations such as direct cathode recycling, bioleaching (microbial extraction of metals), and robotic disassembly promise to make recycling safer, more efficient, and environmentally friendly.
