Electric Double Layer Capacitors (EDLC)

An Electric Double Layer Capacitor (EDLC), also known as a supercapacitor, is a type of electrochemical capacitor that has a higher energy density than a typical capacitor. It is composed of two electrodes made of metal and graphite, with an electrolyte between them, and a separator between the electrodes. This combination allows for a much larger surface area for charge storage than regular capacitors, which gives it greater charge storage capacity and energy density. The SCMS22D255MRBB0 is an EDLC that is often used in power electronics applications due to its high energy density.

Working Principle

Electric Double Layer Capacitors work on the principle of an electrochemical double layer. This is when two layers of charge are separated by a thin membrane that acts as the electrolyte. The positively charged layer, called the "acceptor" layer, is composed of the electrolyte and the negatively charged layer, called the "donor" layer, is composed of the two electrodes and the separator. When an electric field is applied, the positive ions of the donor layer migrate to the acceptor layer and the negatively charged ions migrate to the donor layer. This creates a double layer of charge which is responsible for the storage of electrical energy.

Application Field

The SCMS22D255MRBB0 Electric Double Layer Capacitor is primarily used in power electronics applications due to its high energy density.
