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.
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.
Furthermore, to effectively deploy supercapacitors as the supplementary energy storage system with batteries, different shortcomings of the supercapacitors must be effectively addressed. Supercapacitors lack better energy density and ultralong cyclic stability is a very important desirable property.
Compared to batteries, capacitors have a lower energy density, storing less energy per unit of volume or mass. This makes them less suitable for long-duration energy storage. Another key difference is the self-discharge property: capacitors tend to lose their stored energy relatively quickly when not in use.
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.
This approach addresses the common limitation of batteries in handling instantaneous power surges, which is a significant issue in many energy storage applications. The development of a MATLAB Simulink model to illustrate the role of supercapacitors in reducing battery stress is demonstrated.
