Various classes of dielectric materials have been developed for high-temperature capacitors, but each has its own limitations. Normally, ceramics can withstand high temperature and exhibit high ɛr, but low breakdown strength (E b) and large variation of dielectric properties versus temperature limit their applications.
High-temperature designs incorporate metals such as tin, palladium-silver and gold plating which have melting points well above the temperature rating of the capacitor. These materials perform well at elevated temperatures and should be considered a critical part of the construction in such a demanding environment.
The supply of high-temperature ceramic capacitors for applications above 175 C is highly fragmented, with many of the smaller, more specialized vendors of ceramic capacitors offering a variation on the high temperature ceramic capacitor. Tantalum – Certain types of tantalum capacitor designs are used in high temperature applications.
To achieve high E b, Manoharan et al. invented flexible glass film for high-temperature capacitors. Very high U e (10–35 J cm −3), high efficiency (>90%) and excellence E b (>700 MV/m) over a broad temperature range (25–150°C) were obtained in alkali-free aluminoborosilicate glasses films.
The development of flexible supercapacitors (FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of high-temperature-tolerant FSCs (HT-FSCs).
However, low E b of ceramics and low ɛ r of glass, unstable temperature-dependent permittivity, the increasing hysteresis and conduction loss are limiting factors for high-temperature capacitors. A variety of inorganic bulk and thin films dielectrics have been exploited for high-temperature applications.
