Application Overview — Electronics Recycling
Battery Sorting in Modern Recycling Facilities
Battery recycling is experiencing explosive growth driven by EV battery end-of-life volumes and regulatory mandates for battery recovery (EU Battery Regulation requires 70% lithium recovery by 2030). Battery sorting separates different battery chemistries — critically, lithium-ion (Li-ion) from nickel-metal hydride (NiMH), lead-acid, and alkaline — because each requires a different recycling process. Cross-contamination between battery chemistries can cause dangerous reactions during mechanical processing.
Material Characteristics and Sorting Challenges
Battery sorting challenges: identifying battery chemistry from external appearance alone is impossible for many form factors (cylindrical Li-ion and NiMH cells look identical); damaged, swollen, or corroded batteries have altered visual and spectral characteristics; batteries can retain charge and pose fire/explosion risk during mechanical handling; and the diversity of battery form factors (cylindrical, prismatic, pouch, button) requires flexible handling systems.
Recommended Sorting Technology Stack
XRT (density-based pre-separation: lead-acid batteries are 3-5x denser than Li-ion) + RGB + AI (visual chemistry identification by terminal configuration, casing color, labeling) + induction (metallic content verification). For discharged/dismantled cells: LIBS or XRF for elemental chemistry verification. Fire suppression systems integrated throughout the sorting line.
Performance Benchmarks
| Metric | Target |
|---|---|
| Chemistry ID Accuracy | >98% |
| Li-ion Recovery | >95% |
| Throughput | 1-5 t/h |
| Safety Systems | Thermal imaging, gas detection, auto-suppression |
These benchmarks represent achievable performance with modern sensor-based sorting equipment, assuming properly sized, well-maintained equipment operating on representative feedstock. Actual results depend on specific material composition, throughput, and operating conditions.
