How to Recycle EV Battery Cells
Individual lithium-ion cells from EV battery systems, typically cylindrical (Tesla) or pouch (most others) format. These are the fundamental energy storage units and can be tested, refurbished, or recycled. Each cell contains valuable materials worth $5-50 depending on chemistry and condition.
- 1Only handle cells if you're a certified technician
- 2Ensure cells are discharged to safe voltage (<3.0V)
- 3Wear appropriate PPE and work in well-ventilated area
- 4Test individual cell voltage and internal resistance
- 5Sort cells by chemistry type and condition
- 6Package cells in non-conductive, fire-resistant containers
- 7Use proper UN-certified packaging for transport
- 8Document cell specifications and test results
- 9Contact certified recycler for proper disposal
- Certified battery cell recyclers
- EV battery testing facilities
- Second-life battery companies
- Specialized electronics recyclers
- Research institutions and universities
Individual EV battery cells can still contain dangerous voltage and pose fire risks. They should only be handled by certified professionals with proper safety equipment and procedures.
Recycling individual cells allows for more precise material recovery and sorting. Good cells can be refurbished for second-life applications, while degraded cells are recycled for material recovery.

Can I use old EV battery cells for DIY projects?
Only if you have proper knowledge and safety equipment. EV cells can still contain dangerous voltage and pose fire risks. Consider working with certified professionals instead.
What's the difference between different cell chemistries?
NMC (Nickel-Manganese-Cobalt) cells have high energy density, LFP (Lithium Iron Phosphate) cells are safer and longer-lasting, and NCA (Nickel-Cobalt-Aluminum) cells offer high performance.
How do I know if an EV battery cell is still usable?
Only certified testing can determine cell condition. Factors include voltage, capacity, internal resistance, and physical condition. Good cells typically maintain 80%+ of original capacity.
