Rutronik UK stocks Eaton cylindrical hybrid supercapacitors with eight times higher energy density

The new HS/ HSL Hybrid Supercapacitors from Eaton provide a power density that is up to three times that of lithium-ion batteries. They have an energy density up to eight times higher than conventional EDLCs (Electric Double Layer Capacitor), in a 3.8 V hybrid cell. The Eaton products are now available at Rutronik UK.

Hybrid supercapacitors are energy storage devices that combine the advantages of electric double layer capacitors and lithium-ion technology to achieve higher energy densities and longer life. In the hybrid supercapacitors, a lithium-doped carbon electrode replaces one of the carbon-based electrodes. With more than 250,000 charging cycles at 20°C ambient temperature and a maintenance-free service life of up to 20 years, the hybrids score points over conventional batteries.

At operating temperatures of down to -25°C (HSL) and up to +85°C (HS), the hybrid supercapacitors work without any problems. While HSL supercapacitors are optimized for lower temperatures down to -25 °C, HS supercapacitors have an extended range up to +85 °C and are optimized for higher temperatures.

Thanks to their low self-discharge, they act as stand-alone energy storage devices or are used in addition to battery systems to optimize system costs, service life and runtimes. This makes them particularly suitable for emergency power supplies in server rooms or in medical environments, IoT energy storage, smart metering, tracking of commercial vehicles / containers, but also for impulse and hybrid power supply systems.
