Reference for the use of electrode sheet
1. Electrode cutting: Punching machine, coin cell electrode recommended size: diameter 12mm/14mm
2. Weighing: Balance, active substance calculation formula: active substance mass=
(Mass of electrode (mg) - Circular area (cm2) * Density of current collector surface (mg/cm2) * Proportion of active substance
3. Electrode sheet baking: DZF-6050 (53L) vacuum drying oven
Temperature: 60-80 ℃ Time: 2-4 hours
4. Electrode sheet assembly: single station glove box, small hydraulic button battery sealing machine
Recommended battery assembly sequence: negative case - sodium chips- electrolyte - separator - electrolyte - electrode sheet - gasket / spacer- spring - positive case
5. Battery testing: 5V10mA 8 channel battery tester
Calculate the mass of the active substance, input the corresponding current magnitude, and voltage range.
Current calculation: 0.1C=1C (active substance mass mg × 0.001 × nominal specific capacity mAh/g) × 0.1
Item | Parameter |
Size | 241mm L x200mm W |
Coating area | 241mm L x 175mm W(double side blank 12.5mm) |
Coating side | Single side coating(pressed) |
Current collector thickness | 16 μm |
Coating surface density | 14.5 ±0.20mg/cm2 |
Tap density | 2.6 ±0.1g/cm3 |
Current collector surface density | 4.22mg/cm2 |
Active substance mass fraction | 95.5% |
Half-cell voltage platform | 2.0-4.0 |
Reference specific capacity | 120mah/g (0.1C) |
Matters need attention | 1. The proportion of electrode sheet active substances is based on the physical label, and there is a formula for calculating polar active substances below 2. After opening the electrode sheet, pay attention to sealing and storage. It can be stored in a glove box or a 45 ℃ vacuum oven 3. Electrode sheets are prone to absorbing water, so try to avoid contact with air and moisture as much as possible |
