Details
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.
Operating Steps:
At room temperature (25℃), let stand for 4 hours.
Discharge at 0.10C rate (constant current) to 0.005V, then at 0.09C rate (constant current) to 0.005V.
Discharge at 0.08C rate (constant current) to 0.005V, then at 0.07C rate (constant current) to 0.005V.
Discharge at 0.06C rate (constant current) to 0.005V, then at 0.05C rate (constant current)... Discharge to 0.005V at a constant current rate.
Discharge to 0.005V at a constant current rate of 0.04C, and 0.005V at a constant current rate of 0.03C.
Discharge to 0.005V at a constant current rate of 0.02C, and 0.005V at a constant current rate of 0.01C.
Let stand for 3 minutes.
Charge to 2.00V at a constant current rate of 0.1C, and let stand for 3 minutes.
1. Vacuum storage or double-sealed storage in a glove box, especially for high-nickel and sodium cathode materials, can increase battery internal resistance if not properly stored.
2. Electrodes not rolled: Rolling is required according to the recommended compaction density.
3. Coating surface density must be determined based on actual weighing results. Coating surface density does not include the current collector.
4. Actual weighing calculation of active material mass (mg): = (Small disc weight (mg) - Current collector surface density (mg/cm²) * Small disc area (cm²)) * Active material ratio
5. Theoretical active material amount (mg): = Coating surface density (mg/cm²) * Active material ratio * Small disc area (cm²)
6. Theoretical surface capacity (mAh/cm²): = Coating surface density (mg/cm²) * Active material ratio * Specific capacity (mAh/g) ÷ 1000
7. Calculate specific capacity based on the actual weighed amount of active material. Due to tolerances in coating surface density, the actual weighing should be used as the standard.
8. Creases: Single-sided electrode sheets are prone to curling after rolling; flattening and packaging may result in creases.
