Recently, film capacitors have achieved excellent energy storage performance through a variety of methods and the preparation of multilayer films has become the main way to improve its energy storage performance.
In other words, the operation performance of film capacitors is largely determined by the properties of polymer films, such as dielectric constant (ε r), dielectric loss (tan δ), breakdown strength (Eb) and electrical resistivity, glass transition temperature (Tg).
The high-temperature breakdown resistance of BOPP is a critical factor that directly impacts the effectiveness of film capacitors. We evaluated the breakdown strength of various BOPP/COC thin film at varying temperatures and analyzed the data using the Weibull distribution.
Currently, research on film capacitors primarily focuses on metalized organic polymer capacitors, which exhibit high charge-discharge rates, high flexibility, and excellent self-healing capabilities, promising good application prospects in areas such as microwave communications, hybrid electric vehicles, and renewable energy.
The electrical characteristics of film capacitors are directly linked to those of the dielectrics used. Modern AC capacitors are usually wound using biaxially oriented polypropylene (BOPP) rolls in combination with thin aluminum foil.
