Compact coin cell supercapacitors offer high power density and long lifetime

Schurter's coin cell supercapacitors are compact electrochemical energy storage devices with a high capacity that can quickly store and release electrical energy. Compared to conventional batteries, they deliver several advantages, including high power density, a long cycle life, and fast charge and discharge rates.

Supercapacitors have around 10% of the energy density of rechargeable batteries of the same weight. However, their power density is ten to a hundred times greater. Supercapacitors can, therefore, be charged and discharged much faster. They can also withstand many more charging cycles than rechargeable batteries, making them ideal as a replacement or supplement wherever high switching loads are required.

The new coin cell supercapacitors are employed in various applications, including backup power supplies, electronic devices, renewable energy systems and medical devices. While they are most commonly used for real-time clock backup, they can also be used for memory backup, battery swap ride-through and LED or audible alarms. The new coin cell supercapacitors are available for horizontal mounting (SCCA) or vertical mounting (SCCC). They can be employed in systems with a voltage of up to 5.5V and have a capacitance value ranging from 100mF to 1,500mF.

Key features include a very compact design, high power density, low leakage current, and a long lifetime.
