Typical Uses

Anode for lithium-ion half cells and full cells

Benchmarking electrolytes, binders and cell hardware

Teaching and method development in battery laboratories

Notes

Electrode calendering should be performed according to the recommended compaction density.

Areal loading should be determined based on actual weighing results.

Before transfer into a glove box, the electrodes should be vacuum dried at 105 °C for 4 hours.

Since the electrodes are single-side-coated, calendering may cause curling issues. Batch-to-batch variation within normal tolerance.
