Question

Can you overcharge a supercapacitor?

Answer 1

Answer:

Overcharging the ultracapacitor was done by charging it with 10 amperes at 3.3 volts. This caused the cell to heat up, and similarly to the burning test, pressure built up inside the cell due to electrolyte decomposition and increase in temperature. ... Ultracapacitors are a remarkably safe way to store energy.
