A research of the characteristics of materials used in the construction of EDLCs

Supercapacitors, also known as EDLC (Electric Double Layer Capacitor), are passive components with exponential accumulation of electrical charge. This paper presents the characteristics of EDLC depending on the materials used in their construction. Thus, using different materials for the electrodes and/or for the electrolyte can influence EDLC performance. The most common electrode is carbon based and is used with an organic or aqueous electrolyte. EDLC has three main forms: active carbon, carbon-based aerogels and carbon nanotubes with organic or aqueous electrolyte.
