What a tonne of black mass contains
| Element | kg / 100 kg | kg / tonne | Recovery |
|---|---|---|---|
| Lithium | 4.1 | 41 | 91% |
| Nickel | 0 | 0 | 98% |
| Cobalt | 0 | 0 | 98% |
| Manganese | 0 | 0 | 98% |
| Copper | 12.4 | 124 | 98% |
| Aluminium | 14.8 | 148 | 98% |
Because LFP black mass carries iron and phosphate rather than nickel and cobalt, refiners watch iron and phosphorus closely — they dilute payable value and complicate lithium recovery.
Reference case
How LFP Prismatic behaves at end of life
Ageing and fade
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.
The knee point
The knee — the point where fade accelerates — usually arrives late, often well past the point a vehicle retires the pack. That is why most retired LFP packs still test in grade A or B territory.
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.
Disassembly
Module-to-pack designs with bolted busbars disassemble cleanly. Cell-to-pack and blade designs bonded with structural adhesive take longer and often push cells straight to the refining route.
Where it works after the vehicle
Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- Solar-plus-storage shifting
- Telecom and data-centre backup
- EV charging buffers
- Commercial peak shaving
Limits
Packaging and transport
Prismatic LFP cans are heavy and rigid: palletise them upright, restrain them against movement and keep terminals capped. Swelling is less common than in pouch cells but any bulged can goes straight to quarantine.
- Below 30% state of charge, recorded per serial
- Terminals capped, service disconnect removed
- UN-approved packaging with non-conductive cushioning
- Damage status declared before pickup

LFP Prismatic: common questions
Is LFP Prismatic worth recycling?
Yes. At current settings a LFP Prismatic pack credits about USD 1.9 per kg as black mass, and grade A modules are worth around USD 58 per kWh in second life.
How does LFP Prismatic age?
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. The knee — the point where fade accelerates — usually arrives late, often well past the point a vehicle retires the pack. That is why most retired LFP packs still test in grade A or B territory.
Is LFP Prismatic safe to transport?
It moves as Class 9 dangerous goods under UN 3480 / UN 3481. Prismatic LFP cans are heavy and rigid: palletise them upright, restrain them against movement and keep terminals capped. Swelling is less common than in pouch cells but any bulged can goes straight to quarantine.
Where does LFP Prismatic work in second life?
Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing. Typical applications: solar-plus-storage shifting, telecom and data-centre backup, ev charging buffers, commercial peak shaving.
