Starting points by electrode system
| Electrode | Budcon materials to evaluate |
|---|---|
| LFP cathode | SP13 · SC10 |
| NCM / NCA cathode | SP13 · SC10 |
| Graphite anode | SP13 · SP42 |
| Silicon / SiOx anode | SP42 · SA40 |
Typical values. Electrode performance depends on active material, binder, solvent, mixing and calendering; cell-level qualification is required.
