| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 95.4% | A — BESS ready | USD 221 |
| Year 4 | 91.1% | A — BESS ready | USD 212 |
| Year 6 | 86.8% | A — BESS ready | USD 203 |
| Year 8 | 82.5% | B — Second life | USD 178 |
| Year 10 | 78.2% | B — Second life | USD 155 |
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 Bajaj Chetak 3501 pack
3.5 kWh, 2 modules, about 20 kg — this is how the Hosur, Tamil Nadu team plans the job.
