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.
Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications due to their high efficiency 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.
An energy storage capacitor test was set up to showcase the performance of ceramic, Tantalum, TaPoly, and supercapacitor banks. The test involved charging the capacitor banks to 5V and keeping the sizes modest. The capacitor banks were then tested for charge retention and discharge duration under a pulsed load, which mimics a high power remote IoT system.
Capacitors and batteries are different types of energy storage technologies. Capacitors charge and discharge very quickly compared to battery technology and are optimal for energy harvesting/scavenging applications. Depending on power requirements, capacitors can even replace batteries altogether.
Capacitors possess higher charging/discharging rates and faster response times compared with other energy storage technologies, effectively addressing issues related to discontinuous and uncontrollable renewable energy sources like wind and solar .
Hence, to make full use of the storage capacities, it is important to ensure that the capacitor is fully charged. In an idealized case, the SC is charged at V1 = Vr and during the operation entirely drained down to V2 = 0 V. Due to this voltage dependence, it is important to know the parameters of the DC-DC converter in the surrounding circuit.
