Where a Ather Rizta Z pack goes from Sriperumbudur, Tamil Nadu
- 1
Collected via Zaheerabad, Telangana
Whole packs enter the network at Hyderabad — Zaheerabad Recovery Campus, 581 km away, where they are weighed and de-energised.
- 2
Graded at Hosur, Tamil Nadu
Modules travel 230 km to Bengaluru — Hosur Diagnostics Centre for capacity, resistance and impedance testing across all 2 modules.
- 3
Second life at Butibori, Maharashtra
At 80% SOH about 56% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (893 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refining at Sriperumbudur, Tamil Nadu
Black mass from failed modules is leached and refined here into battery-grade lithium salts.

Inside the Ather Rizta Z battery
The Ather Rizta Z (2024) carries a 3.7 kWh LFP Prismatic (LiFePO4) pack with 2 modules at 52 V, weighing roughly 27 kg. Cobalt-free prismatic chemistry dominant in Indian passenger EVs and commercial fleets. Low black mass value, exceptional second-life economics.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 96.4% | A — BESS ready | USD 194 |
| Year 4 | 93.3% | A — BESS ready | USD 188 |
| Year 6 | 90.2% | A — BESS ready | USD 182 |
| Year 8 | 87.1% | A — BESS ready | USD 176 |
| Year 10 | 84% | B — Second life | USD 152 |
What the chemistry means here
How it ages
LFP fades slowly and fairly linearly for most of its life. Capacity loss is driven mainly by lithium inventory being locked up in the SEI layer on the graphite anode, while the cathode structure stays largely intact.
Thermal behaviour
LFP's olivine cathode holds its oxygen tightly, so thermal runaway typically starts at higher temperatures than nickel-rich cells and releases noticeably less heat. It is not inert: a failing LFP cell still vents flammable electrolyte vapour and hydrogen, and large prismatic cans store a lot of energy in one place.
Handling LFP Prismatic
Collecting a Ather Rizta Z pack
3.7 kWh, 2 modules, about 27 kg — this is how the Sriperumbudur, Tamil Nadu team plans the job.
Removal
Removable packs are unclipped by hand; fixed packs are removed at the dealer bench with the frame supported.
Packaging
Packs travel in UN-approved steel or plastic cages with non-conductive dividers, typically dozens per cage.
Consolidation
Dealer and swap-station returns are aggregated at a single point so one collection clears many units.
Before the truck arrives
- Tape terminals and connectors on every pack
- Separate swollen or dropped packs into their own container
- Record serials in a single list per cage
- Store below 30% charge away from charging racks
Sriperumbudur, Tamil Nadu site notes
- Whole packs are not accepted; route them through a grading or integrated campus first and the black mass will follow.
- Black mass must arrive in sealed, labelled bulk bags with an assay report or at least a declared chemistry.
- Deliveries are scheduled against SEZ gate windows, and imported material needs customs paperwork before arrival.
- Moisture above the agreed limit is recorded at the weighbridge and reflected in settlement.

Rules in India
Battery Waste Management Rules 2022 (BWMR)
Regulator: Central Pollution Control Board (CPCB) and State Pollution Control Boards
The refinery is permitted by the Tamil Nadu Pollution Control Board, with effluent, air emission and hazardous-chemical conditions typical of acid-leaching plants. As a registered recycler under the Battery Waste Management Rules 2022, it generates the recovery evidence that producers file on the CPCB EPR portal. Its SEZ location adds customs controls on any imported feed or exported product.
