Although commercial supercapacitors operate in a temperature range of −40 to 70 °C, this range cannot satisfy the requirements of the some practical applications. Thus, designing electrolytes with high thermal stability and high ionic conductivity over a wider temperature window remains an important challenge.
The ambient temperatures, where the supercapacitors are deployed, have a major influence particularly at the extremes. Most supercapacitor manufacturers specify the safe operating temperatures in the range of −40 to 70°C. Chapter 2 presents more treatment of the subject matter on Thermal Considerations for Supercapacitors.
The operating temperature of a supercapacitor has a significant influence on its performance characteristics. Many performance variations, however, can be attributed simply to the change in physical properties of the electrolyte with temperature.
On the extreme high-temperature side, for example, in downhole drilling where temperatures are above 120°C, the supercapacitors' ability to function is limited by their electrolytes. Ionic liquids are used in high temperature applications because of their good thermal stability and low vapor pressure.
For example, designing a 0-700C supercapacitor into a system that will experience 850C ambient temperature is not recommended, regardless of whether the temperature increase is temporary. The industry has adopted a few standards to help determine the expected life of a supercapacitor based on the materials used and the design of the component.
