Wanted: Damaged or discarded 280Ah EVE cell, preferably one that was sold to you as "new".
Goal: Detailed teardown after full discharge for cell parameter estimation as input for analytical cell model.
Offer: USD 10 (+ shipping if feasible)
Destination: Sacramento, CA, USA. I may be able to pick up the cell myself if within ~30min drive.
Contact: Please send me a private message if you think you may have an acceptable cell as described below.
Acceptable "damage" types are those that can have a negligible effect on the overall thickness of the "jelly rolls", like

Acceptable "damage" types are those that can have a negligible effect on the overall thickness of the "jelly rolls", like
- too low capacity,
- case damage (scratches; small dents, i.e. <25mm or 1in), and
- terminal damage (e.g. stripped terminal threads or damaged terminal faces).
- leaking cells, i.e. losing or lost electrolyte,
- popped cell overpressure valve,
- excessive swelling / bulging (>3mm or 1/8" w.r.t. nominal thickness of 71.5±1.0mm at 30% S0C), and
- one or more overcharge(s) or overdischarge(s).
