Why Use Series/Parallel Combinations of Ultracapacitors?
An ultracapacitor cell can only withstand low voltages. In general, if cells are operated above their rated voltages for a long period of time, their...
Read postWhat Is Self-discharge and Leakage Current?
Over time, charged ultracapacitors without a load slowly lose their charge. “Self-discharge” is the voltage drop a charged ultracapacitor cell experiences after a set period...
Read postWhat Is End-of-life and Failure Mode for an Ultracapacitor?
In general, ultracapacitors do not have a hard end-of-life failure as do batteries. Their end of life is defined as when the capacitance and/or ESR...
Read postWhat Is the Difference between Power and Energy?
Although it is common to use the terms power and energy interchangeably, they are not the same. Energy is the amount of work that can...
Read postHow Do Ultracapacitors Differ from Batteries?
Portable applications and digital technology have outpaced traditional chemical battery technology. A typical symptom of insufficient battery performance is the ratio of time the appliance...
Read postWhat Are Ultracapacitor Advantages and Limitations?
Ultracapacitors have several distinct advantages, the first of which is their high energy storage. Ultracapacitors possess energy density that is several times higher than that...

Read postHow Are Ultracapacitors Constructed?
The specifics of ultracapacitor construction are dependent on the manufacturer and the intended application. The materials may also differ slightly between manufacturers or due to...
Read postHow Do Ultracapacitors Work?
Generally, capacitors are constructed with a dielectric (insulator) placed between two metal plates that serve as conductors; energy is stored when, during the charging process,...
Read postWhat Is an Ultracapacitor?
Ultracapacitors, also known as electrochemical double-layer capacitors (EDLCs), are electrochemical capacitors that possess an unusually high power and energy density when compared with traditional capacitors—typically...
