Question

Quizplus · Accepted Answer

Although supercapacitors have advantages such as faster charging times and longer cycle lives, they still have lower energy densities compared to batteries. This means that they cannot store as much energy per unit of volume or weight. For portable electronic applications, where size and weight are important factors, batteries are still preferred over supercapacitors because they can provide more energy in a smaller package.
