In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver. A defibrillator (Figure (PageIndex{2})) delivers a large charge in a short burst, or a shock, to a person''s heart to correct abnormal heart rhythm (an arrhythmia). A heart attack can arise from the onset of fast, irregular beating of the heart—called cardiac or
From the plot in Figure 1, it can be seen that supercapacitor technology can evidently bridge the gap between batteries and capacitors in terms of both power and energy densities.Furthermore, supercapacitors have longer cycle life than batteries because the chemical phase changes in the electrodes of a supercapacitor are much less than that in a battery during continuous
Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
