Battery Cell Build Tracking: From Pouch Cell to Electrode and Material Lot

Trace a pouch cell back to its material lots, and a lot forward to every cell it reached.
0:38

The problem: cell builds you can't trace in both directions

When a material lot is suspect, teams need to know which cells used it. When a cell fails, they need its lots. Without linked records, both answers take digging.

A pouch cell is built from electrodes, which are built from slurries, which are built from material lots. When a lot is questioned, the team needs to follow that chain down to every affected cell, and when a cell fails, back up to its lots.

What this demo shows

  1. Open Related Experiments on a cell.
  2. Follow it back through electrodes and slurries to the material lots.
  3. Add lot links.
  4. Open a lot and follow it down to the cells it reached.

‍

Why it matters

Lot traceability limits the impact of a bad material. Knowing exactly which cells a lot reached lets the team quarantine only what's affected.

The same links help in the other direction, connecting a cell's performance to the materials behind it.

Read the transcript

Uncountable keeps experiment data structured, so a cell links back to its material lots. Pouch cell PCB03 from design B of the build. Related experiments shows what went into it. Its anode, cathode, and FEC electrolyte. Above each electrode is its slurry. Add lot links to see the material lot behind each slurry. If a lot is in question, open it to trace the cells that used it.

From cell to material lot, traced in Uncountable.

FAQs

Can I trace a pouch cell to its material lots?

Yes. Related Experiments shows the cell's anode, cathode and electrolyte, the slurry behind each electrode, and the material lot behind each slurry.

Can I find every cell that used a material lot?

Yes. Open the lot to trace the cells that used it.

Why does this matter?

If a lot is in question, you can see straight away which cells it reached.
