Reference for Electrode Sheet Usage
- Electrode Sheet Cutting
Equipment: MSK-T10 sheet cutter
Recommended size for coin cell electrode sheets: 12mm/14mm in diameter - Electrode Sheet Weighing
Equipment: Sartorius BCE series balance
Formula for active material calculation:
Active material mass = [(Electrode sheet mass (mg) - Disc area (cm²) * Current collector areal density (mg/cm²))] * Active material proportion - Electrode Sheet Drying
Equipment: DZF-6050(53L) vacuum drying oven
Temperature: 60–80°C
Time: 2–4 hours - Electrode Sheet Assembly
Equipment: VGB-10-I single-station glove box, MSK-110 small hydraulic coin cell sealing machine
Recommended battery assembly sequence:
Negative case → Lithium sheet → Electrolyte → Separator → Electrolyte → Electrode sheet → Gasket → Spring sheet → Positive case - Battery Testing
Equipment: 5V10mA8 channel battery tester
Steps: Calculate the active material mass, then input the corresponding current and voltage range.
Current calculation:
0.1C = 1C = (Active material mass (mg) * 0.001 * Nominal specific capacity (mAh/g)) * 0.1
