Instructions For Use
1. The electrode calendering, needs to be calendered according to the recommended compaction density. 2. The surface density needs to be determined based on the actual weighing results. 3. Before placing it in the glove box, the electrodes needs to be vacuum dried at 105 ℃ for 4 hours
Note: Since the electrodes are single-side-coated, calendering may cause curling issues.
