MSE PRO Sodium-ion Battery Hard Carbon Anode Electrode Sheet (5 Pieces)
Introduction
This product is developed for sodium-ion battery research and features a hard carbon electrode sheet using 5 μm hard carbon as the active material on a 12 μm aluminum foil current collector. With a high active material ratio of 95.5% and an areal capacity of 1.73 mAh/cm², it provides a specific capacity of 300 mAh/g within a 0.00–2.00 V window. The electrode sheet is supplied uncalendered and requires roll-pressing to the recommended compaction density prior to use. It is designed for half-cell evaluation of hard carbon anodes, and is also compatible with full-cell configurations using the cathode at an N/P ratio of 1.16. Optimal performance is achieved with the recommended KLD-NC06 electrolyte under specified test conditions. The product should be stored under vacuum or in a glove box and used within one month after opening to avoid performance degradation.

*This product must be tested in accordance with the recommended test methods and electrolytes to achieve the corresponding performance. Since the test method and electrolyte have a great influence on the performance of the battery, any change in the test method or electrolyte may reduce the performance of the pole piece; be sure to check this information before purchasing.
