Energy storage technology continues to grow rapidly to answer the needs of various devices. Battery, fuel cells, and flywheels batteries are examples of common energy storage devices. Among these technologies, super capacitors appear as an alternative battery with promising potential. The increasing demand for energy storage devices has led to a significant interest in super capacitors, which have the potential to replace traditional batteries in various applications.
Background
Super capacitors, also known as ultracapacitors, are energy storage devices that store electrical energy through electrostatic double-layer capacitance and electrochemical pseudocapacitance. They have several advantages over traditional batteries, including high power density, long cycle life, and fast charging and discharging capabilities. These characteristics make super capacitors an attractive alternative to traditional batteries in various applications, including mobile phones, electric vehicles, and renewable energy systems.
