What is a High Temperature Ultracapacitor?

In general, an ultracapacitor, also known as supercapacitor or electrical double layer capacitor, is an device that stores energy through electrostatic forces rather than chemical reactions. Ultracapacitors can store much more energy than regular electrolytic or tantalum capacitors, and can provide higher power than batteries due to their lower internal resistance. Ultracapacitors are excellent devices for high power, pulsed power, and long-life applications.

A significant advantage of Nanoramic's FastCap® High Temperature Ultracapacitors is the ability to operate in high temperature environments. Before Nanoramic® released its FastCap® Extreme Environment Ultracapacitors Series,  the maximum operating temperature of ultracapacitors available on the market was between 65°C and 75°C.  FastCap® ultracapacitors are able to safely and reliably operate at 100°C, 125°C and 150°C.

Nanoramic® was able to push the technology limits for the operating temperature under two U.S. Government grants. In 2012, under the Energy Efficiency and Renewable Energy (EERE) Geothermal Technologies Program, Nanoramic® developed an ultracapacitor operating at 250°C. This result has been validated by Sandia National Laboratory. In 2014, Nanoramic® Labs received an additional grant from NASA to develop a high temperature ultracapacitor for extreme environments able to operate at 300°C. The project title was: Ultra-High Temperature Solid-State Ultracapacitor Module Operating at 350°C For Extreme Environments. During this program, Nanoramic® reported data of an energy storage device operating at 350°C.

Nanoramic® has developed techniques and methods to optimize the internal components of our ultracapacitor, obtaining unprecedented advantages in high-temperature performance over the current state of the art technology.
