Hybrid Supercapacitors

August 16, 2020 by Eaton Electronic Components

Eaton hybrid supercapacitors are high reliability, high power, ultra-high capacitance energy storage devices utilizing proprietary materials and processes.

Eaton HS hybrid supercapacitors are small-footprint, high-power energy storage devices ideal for a host of energy and industrial applications. Eaton’s HS supercapacitors comprise new proprietary materials. Each supercapacitor has two electrodes, one similar to that of a battery and one a standard supercapacitor electrode. Consequently, their energy densities are closer to those of conventional batteries and up to 10 times higher than standard supercapacitors. 

Each hybrid cylindrical cell offers between 30 F and 220 F of capacitance with a maximum working voltage of 3.8 V, an operating temperature range from -25 °C to +70 °C, and ultra-low ESR. HS supercapacitors can be utilized as sole energy storage or alongside batteries to optimize system cost, lifetime, and runtime. While HSL supercapacitors are optimized for lower temperatures, going down to -25 °C, HS supercapacitors have an extended range to +85 °C and are optimized for higher temperatures.
