From Stuttgart, Germany
Where a Renault Zoe R135 pack goes from Stuttgart, Germany
- 1
Collected via Dubai, UAE
Whole packs enter the network at Dubai — Jebel Ali Logistics Yard, 4,759 km away, where they are weighed and de-energised.
- 2
Module grading at Stuttgart, Germany
All 12 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Zwickau, Saxony
At 80% SOH about 47% of the pack qualifies for reuse and goes to Zwickau — Saxony Second-Life Works (321 km). Good — grade-A modules above 80% SOH qualify for commercial-scale BESS strings.
- 4
Refined at Lyon, France
Remaining modules are shredded to black mass and refined at Lyon — Auvergne-Rhone-Alpes Refinery, 469 km away.

| Year 4 | 90.4% | A — BESS ready | USD 3,127 |
| Year 6 | 86.1% | A — BESS ready | USD 2,966 |
| Year 8 | 81.8% | B — Second life | USD 2,579 |
| Year 10 | 77.5% | B — Second life | USD 2,260 |
What the chemistry means here
How it ages
NMC 811 loses capacity through a mix of SEI growth, cathode surface reconstruction and micro-cracking of nickel-rich particles. Resistance climbs faster than in LFP, which matters as much as capacity for second-life duty.
Thermal behaviour
High-nickel NMC cathodes release oxygen as they decompose, so once runaway starts it is fast and energetic. Cylindrical 2170 cells vent through a designed rupture point, which helps, but cell-to-cell propagation inside a tightly packed module is the main hazard.
Handling NMC 811 (2170)
Collecting a Renault Zoe R135 pack
