High-Temperature Degradation Tests on Electric Double-Layer Capacitors: The Effect of Residual Voltage on Degradation

“…One possible solution is to increase the operating voltage [ 10 , 11 ]. However, in addition to high temperatures, using voltages higher than the rated voltage (1 V for aqueous EDLCs and 2.5 to 3 V for organic EDLCs) accelerates the degradation of EDLCs [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Various degradation tests involving high temperatures and voltages have been reported previously.…”

Modeling of Equivalent Circuit Analysis of Degraded Electric Double-Layer Capacitors

“…However, the most serious problem when applying EDLCs to vehicles is their degradation. The degradation of EDLCs is enhanced by harsh environments, such as high temperature and voltage [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ], and EDLCs are actually exposed to such environments in vehicles. Therefore, it is necessary to continuously monitor and diagnose the conditions of EDLCs; otherwise, sudden malfunctions or an efficiency drop cannot be avoided.…”

Observation of Drench of Porous Barrier Materials with Employment of the Conductivity Sensor

“…Specific tasks pointed to formation of conditions for deployed forces in the environment with chemical, radioactive and biological contamination quite unambiguously are a part of professional gesture of the Czech Armed Forces Chemicals Corps [8][9][10][11]. One of conditions of forces survival in areas contaminated with chemical, radioactive and biological agents is their provision with high quality individual protective equipment (IPE) that will be made of the first-rate barrier materials and, moreover, will meet a number of specific demands [12,13]. One of them is the resistance of IPE´s barrier materials against permeation (penetration or drench), which should be relevantly investigated and evaluated.…”
