Supercaps, also known as supercapacitors, are a special type of energy storage devices that combine the properties of rechargeable batteries with those of capacitors. They can store enormous amounts of energy and release them very quickly, making them extremely valuable for many applications.
Compared to rechargeable batteries of the same weight, supercapacitors have only about 10% of the energy density. However, their power density is ten to a hundred times higher. Supercapacitors can therefore be charged and discharged much faster. They can also withstand many more charging cycles than rechargeable batteries and are therefore suitable as a replacement or supplement wherever high switching loads are required.
Power Density vs Energy Density
Power density describes how quickly an energy storage device can release or store energy. Power density is crucial for applications that require a high energy output in the short term, such as starting a motor. Supercapacitors are characterized by a high power density, which allows them to deliver energy very quickly. Energy density describes how much energy a storage device can retain over a longer period of time. High energy density is essential for applications that require a continuous supply of energy.
The world's thinnest supercapacitors
SCHURTER's prismatic supercapacitors are super thin. With a thickness of only 0.4 mm, a variant of the SCHURTER SCPA family is currently the thinnest supercapacitor in the world.
Applications
The new supercapacitors from SCHURTER are ideal for demanding applications that require high capacitance in the most compact dimensions. For example in mobile devices, portable electronics, sensor technology, small power supplies or devices with mobile energy generation and uninterruptible power supplies.
