High-performance ultra-thin supercapacitors

SCHURTER'S supercapacitors, also referred to as supercaps, are advanced energy storage components that integrate characteristics of traditional capacitors and rechargeable batteries. They are capable of storing substantial amounts of energy and delivering rapid energy discharge, making them particularly advantageous in a wide range of high-performance applications.

While supercapacitors generally exhibit approximately 10% of the energy density of rechargeable batteries, they provide a significantly higher power density – ranging from 10 to 100 times greater. This distinction allows supercapacitors to charge and discharge at much faster rates. Further, they exhibit superior cycle durability, enduring significantly more charge and discharge cycles than conventional batteries. These attributes make supercapacitors particularly suitable for use in environments demanding high switching loads, whether as a supplement to or a replacement for batteries.

Power density vs energy density

Power density refers to the rate at which energy can be transferred to or from the storage device. This parameter is crucial for applications that require high-energy bursts over short durations, such as engine startup sequences. Supercapacitors, characterized by their high-power density, are well suited to these tasks.

In contrast, energy density quantifies the total amount of energy a storage device can hold over an extended period. Applications requiring a sustained energy supply benefit more from devices with high energy density, such as traditional batteries.

World's thinnest prismatic supercapacitors

SCHURTER's prismatic supercapacitor portfolio features one of the thinnest supercapacitor variants currently available, measuring just 0.4mm in thickness. This makes it the thinnest known supercapacitor on the market to date.

Typical applications

The company's latest generation of supercapacitors is engineered for applications demanding high capacitance in extremely compact form factors.

Typical use cases include:

• Mobile and handheld electronic devices
• Wearable electronics
• Sensor technology
• Compact power supply units
• Devices employing mobile energy generation
• Uninterruptible power supplies (UPS)

These supercapacitors deliver an optimal solution where space constraints and high performance are vital design considerations.
