Inside the Ola Electric S1 Air battery
The Ola Electric S1 Air (2023) carries a 3 kWh NMC 811 Cylindrical 2170 pack with 2 modules at 48 V, weighing roughly 17 kg. High-nickel cylindrical cells with the strongest hydrometallurgical recovery credit per tonne of black mass.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 95.2% | A — BESS ready | USD 189 |
| Year 4 | 90.9% | A — BESS ready | USD 181 |
| Year 6 | 86.6% | A — BESS ready | USD 174 |
| Year 8 | 82.3% | B — Second life | USD 151 |
| Year 10 | 78% | B — Second life | USD 132 |
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 Ola Electric S1 Air pack
3 kWh, 2 modules, about 17 kg — this is how the Sriperumbudur, Tamil Nadu team plans the job.
