Advanced Materials

In 2018, FastCAP Ultracapacitors developed Nanoramic, a division which specializes in material solutions based on nano-carbons. Nano-carbons have exceptional electrical, thermal and mechanical properties at the nano-scale level. Nanoramic synthesizes and incorporates nano-carbons in various materials and transfers these properties at the macroscale level, addressing the needs of several applications.


Industry Leading Ultracapacitor Technology

With roots in geothermal research, FastCAP has pioneered extreme environment ultracapacitor technology. We have developed an expertise in creating high performance Ultracapacitors based on advances on the nanomaterial, electrolyte, cell construction and processing levels.

Today, FastCAP is the only company with ultracapacitors capable of high temperature (>125°C), low temperature (< -55°C), and hermetically sealed capacitors capable of enduring the space environment.  FastCAP’s technology has been validated from -110°C to 250°C by Sandia National Laboratory.

How Can Hard Drive Manufacturers Store More Data? Ultracapacitors

November 17, 2017

Katie Willgoos


We are living in a fully digitalized era, where the amount of data we generate every day is huge. Actions like shooting a 60-second video, taking a bunch of high-definition pictures, and sending multiple text messages have become part of our everyday lifestyle. Today, the estimated amount of data we generate daily is 2.5 exabytes, the equivalent of 2,500,000,000 Gigabytes (2.5 Quintillion bytes = a lot of bytes). While the current amount of data being generated is enormous, the rate at which we are making it...


What is a High Temperature Ultracapacitor?

June 22, 2017

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 FastCAP's ultracapacitor...
