Eaton's HS/HSL hybrid supercapacitors offer up to three times the power density of lithium-ion batteries and deliver up to eight times the energy density of conventional EDLCs (Electric Double Layer Capacitor) in a 3.8V hybrid cell. Hybrid supercapacitors combine the advantages of electric double layer capacitors and lithium-ion technology to achieve their higher energy densities and long service life. In hybrid supercapacitors, one of the carbon-based electrodes is replaced by a lithium-doped carbon electrode.
With over 250,000 charging cycles at ambient temperatures of 20 °C and a maintenance-free service life of up to 20 years, the hybrids outperform conventional battery solutions. At operating temperatures down to -25 °C (HSL) and up to
+85 °C (HS), the hybrid supercapacitors work without any problems. The HSL versions are optimized for lower temperatures down to -25 °C, while the HS versions have an extended range up to +85 °C and are optimized for higher temperatures.
Thanks to their low self-discharge, the hybrids can be used as stand-alone energy storage units or 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, as IoT energy storage systems, for smart metering, tracking commercial vehicles and containers, but also in pulse and hybrid power supply systems.
