Capacitors for Energy Storage Applications Energy storage capacitors can typically be found in remote or battery powered applications. Capacitors can be used to deliver peak power, reducing depth of discharge on batteries, or provide hold-up energy for memory read/write during an unexpected shut-off.
There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
Capacitors use an electric charge difference to store energy. Capacitor energy storage systems can smooth out power supply lines, removing voltage spikes and filling in voltage sags. They are particularly useful in power quality applications where the rapid charging and discharging capabilities of capacitors are crucial.
Supercapacitors, also known as electric double layer capacitors (EDLC), store energy by achieving a separation of charge in a Helmholtz double layer at the interface between the surface of a conductive electrode and an electrolyte. Their energy density is typically hundreds of times greater than conventional capacitors.
Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.
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.
