Ocena jakości superkondensatorów wybranymi metodami, wykorzystując zjawiska losowe i badania rozkładu temperatury
PublikacjaW artykule przedstawiono metody analizy jakości wykonania próbek superkondensatorów na podstawie pomiarów szumów generowanych w ich strukturach oraz rozkładów temperatury na ich powierzchni. Prezentowane metody zostały porównane z obecnie stosowanymi parametrami oceny jakości tych elementów. Wyniki uzasadniają wprowadzenie dodatkowych parametrów, pozwalających oceniać jakość superkondensatorów.

Temperature distribution of supercapacitors prepared by various technologies
PublikacjaSupercapacitors, also known by different names such as electrostatic double-layer capacitors (EDLCs) or ultra-capacitors, are electrical storage devices still in development. These devices require fast and reliable methods of assessing their state-of-health. Thermographic imaging is a method which can be applied with this aim due to its popularity, and the high negative impact of overheating on a supercapacitor’s parameters. Moreover,...

Effects of mechanical stress on electrical arameters and noise of supercapacitors
PublikacjaResults of noise and electrical parameters measurements of prototype electrochemical double layer capacitors (EDLC) are reported at the presence of selected mechanical stress. This issue is of great importance due to future applications in wearable technology. The measurement results are compared, and we may conclude than flicker noise is more sensitive to any stress than other considered electrical parameters.

Noise in electrical double-layer capacitors (EDLCs)
PublikacjaWe present methods and problems of noise measurements in electrical double-layer capacitors (EDLC). Detailed noise equivalent electronic circuit is considered, and two possible ways of observations of random processes generated in the EDLCs structures are studied. We conclude that noise is a useful tool for characterization of the EDLC structures and their state-of-health, as in other materials and electronic devices. Eventual,...
