Maximum Power in Minimal Space: SCHURTER Prismatic Supercapacitors
Supercapacitors store large amounts of energy and release it extremely quickly, making them highly valuable for numerous applications. SCHURTER’s new line of prismatic supercapacitors sets a new benchmark in energy storage solutions. What exactly are supercapacitors, and what distinguishes SCHURTER’s latest generation? Let’s take a closer look.

What is a Supercapacitor?
A supercapacitor, also known as a supercap or ultracapacitor, is a high-performance energy storage device designed for rapid charging and discharging. Supercaps combine the fast energy delivery of conventional capacitors with the high storage capacity of batteries, making them ideal for demanding applications.
How does a Supercapacitor Work?
Supercapacitors consist of two electrodes separated by an electrolyte. When a voltage is applied, ions in the electrolyte accumulate at the electrode surfaces, forming two charged layers. This phenomenon is known as electric double-layer capacitance (EDLC). This structure enables rapid energy storage and release without degradation caused by chemical reactions.
Supercapacitors vs. Batteries and Accumulators
Compared to batteries and accumulators of the same weight, supercaps have approximately 10% lower energy density. However, their power density is about ten to one hundred times greater. This allows supercaps to charge and discharge much faster. Additionally, they withstand significantly more charge-discharge cycles, making them especially suitable as supplements or replacements for batteries and accumulators in applications with high switching demands.
Power Density vs. Energy Density
Power density indicates how quickly an energy storage device can absorb or deliver energy. It is crucial for applications requiring short bursts of high power, such as motor starting. Supercapacitors impress with their high power density, providing energy almost instantaneously. Energy density reflects how much energy a device can store over a longer period. High energy density is essential for applications needing continuous power supply.
SCHURTER Prismatic Supercapacitors: Ultra-compact yet Powerful
In collaboration with CAP-XX, SCHURTER has developed ultra-thin, high-performance supercapacitors, setting a new standard in energy storage. The thinnest supercaps currently available bridge the gap in power and capacity between conventional capacitors and batteries. These prismatic supercapacitors combine high power density with extremely low equivalent series resistance (ESR) and an ultra-flat form factor – ideal for demanding electronic applications.
