Details

This product is developed for sodium-ion battery research and features a hard carbon electrode sheet (model YT02XX) using imported 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 NT02XX 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.

1. Store under vacuum or in a glove box using two layers of sealed bags, especially for high-nickel or sodium-ion cathode materials. Improper storage may lead to increased internal resistance of the battery.    

2. Electrode sheets are not roll-pressed; they need to be roll-pressed according to the recommended pressing density.    

3. The coating area density should be determined based on actual weighing results, and it does not include the current collector.    

4. Actual active material mass (mg) = (weight of the small disc in mg – current collector area density in mg/cm² × area of the small disc in cm²) × active material ratio.    

5. Theoretical active material amount (mg) = coating area density in mg/cm² × active material ratio × area of the small disc in cm².    

6. Theoretical areal capacity (mAh/cm²) = coating area density in mg/cm² × active material ratio × gravimetric capacity in mAh/g ÷ 1000.    

7. When calculating gravimetric capacity, use the actual weighed amount of active material since the coating area density may have tolerances; the actual weighing takes precedence.    

8. Creases: single-sided electrode sheets tend to curl after roll-pressing; flattening and packaging may cause creases.    

This product must be tested in accordance with the test methods and electrolytes recommended by Coulter 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.
