Technical FAQs 4

What contributes to the thermal resistance of a supercapacitor?

Detailed ex situ temperature measurements of a supercapacitor tested at different compaction pressures have demonstrated that among all components, the main contributor to the thermal resistance of a supercapacitor are the electrodes (see Table 3.8) .

What is a safe operating temperature for a supercapacitor?

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. They have excellent low temperature performance which can meet the power needs in extreme weather conditions in heavy electrical applications.

How do thermophysical properties affect thermal behavior of supercapacitors?

Policies and ethics Thermophysical properties of supercapacitor components determine the thermal behavior of supercapacitors at different application temperatures. A fundamental understanding of the influence of temperature on these properties is necessary to design supercapacitors with...

How does temperature affect a supercapacitor's performance?

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.
