Contact UsIntroduction to Supercapacitors
Supercapacitors are also known as ultracapacitors or double-layer capacitors. They bridge the gap between capacitors and batteries. Supercapacitors display higher energy density than a conventional capacitor and higher power density than batteries. They have high cyclic stability, high power density, fast charging, and good rate capability.

If it was a "wet" capacitor with a gel / liquid electrolyte, that was likely either ethylene glycol (aka "anti-freeze") or boric acid (think Borax laundry soap). If it was a solid capacitor, the equivalent of an electrolyte was another film of manganese dioxide (MnO2). Wet caps usually pop, but not smoke.
