This electrode sheet is based on aluminum foil coated with hard carbon ,used as a cathode electrode of a Na-Ion battery.
eference 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
