The short answer

Selective — only low-swell pouch stacks above 82% SOH are cleared for repurposing. Grade A modules settle near USD 62 per kWh, against a black mass credit of roughly USD 38 per kWh.

Key takeaways

  1. 1Second-life fit for NCA Pouch: Selective.
  2. 2Grade A modules are worth around USD 62/kWh versus about USD 38/kWh as black mass.
  3. 3Matching modules by impedance, not just capacity, keeps strings ageing evenly.
  4. 4Every repurposed module still ends up at a refiner — plan that route from day one.
01

Is NCA Pouch a good fit for stationary storage?

Selective — only low-swell pouch stacks above 82% SOH are cleared for repurposing.

Only low-swell stacks above about 82% SOH are cleared for reuse, and they should never be used in tightly packed, poorly ventilated enclosures.

02

Applications that suit it

Stationary duty is gentler than driving: lower C-rates, shallower cycles and controlled temperature. The best applications play to those conditions.

  • Low-cycle backup only, under strict limits
  • Refining feed for most packs
03

Reuse versus refining: the value gap

For a 60 kWh NCA Pouch pack weighing about 324 kg, the difference between grading modules for reuse and sending the whole pack to refining can be substantial. Reuse also defers the refining cost rather than removing it.

Field note

Most packs split: healthy modules go to storage and weak ones to refining. The calculator on this site models that split for a given SOH.
Questions

Frequently asked questions

Can NCA Pouch modules be reused in home storage?

Only with conservative limits, a new BMS and a fire-rated enclosure. Many installers prefer LFP for residential use.

What warranty do second-life modules carry?

Warranty terms for NCA Pouch are shorter and depend on grade and duty cycle.

Turn this into a plan for your packs

Send pack counts, chemistry and approximate state of health. You get an indicative value split, a slotted collection window and pre-filled dangerous goods paperwork.
