Requires appropriate definition of peak power vs. continuous power Ultracapacitors l Microelectronics l HighVoltage Capacitors 超級(jí)電容的老化 ? Unlike batteries, Ultracapacitors do not have a hard end of life criteria. ? Ultracapacitors degradation is apparent by a gradual loss of capacitance and a gradual increase in resistance. ? End of life is when the capacitance and resistance is out of the application range and will differ depending on the application. ? Therefore life prediction is easily done.
