Whole packs enter the network at Bhubaneswar — Khordha Collection Yard, 331 km away, where they are weighed and de-energised.
- 2
Graded at Pithampur, Madhya Pradesh
Modules travel 1,279 km to Indore — Pithampur Grading Plant for capacity, resistance and impedance testing across all 12 modules.
- 3
Second life at Butibori, Maharashtra
At 80% SOH about 47% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (956 km). Good — grade-A modules above 80% SOH qualify for commercial-scale BESS strings.

Inside the Volkswagen ID.4 Pro battery
The Volkswagen ID.4 Pro (2021) carries a 82 kWh NMC 811 Cylindrical 2170 pack with 12 modules at 400 V, weighing roughly 459 kg. High-nickel cylindrical cells with the strongest hydrometallurgical recovery credit per tonne of black mass.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 94.5% | A — BESS ready | USD 5,125 |
| Year 4 | 90.2% | A — BESS ready | USD 4,921 |
| Year 6 | 85.9% | A — BESS ready | USD 4,646 |
| Year 8 | 81.6% | B — Second life | USD 4,041 |
| Year 10 | 77.3% | B — Second life | USD 3,543 |
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)
