A super Capacitor made using activated carbon.
Activated Carbon 7.5g
PVA glue 5.5g
Distilled water 7g
Separator - paper towel.
Electrolyte - Sodium Sulphate solution.
Current collectors PCB’s – Active area 3.5cm x 5cm = 17.5cm^2.
Discharged to half life 0.6v from 1.2v via 100R in 210 seconds
C=t/0.7xR = 210/0.7x100 = 3F
