Ferroelectric supercapacitors are energy storage devices that use a ferroelectric material as the dielectric layer. This allows for high energy density and fast charge-discharge cycles.
Ferroelectric supercapacitors have a higher energy density due to the use of a ferroelectric material, which allows for a higher electric displacement and polarization. They also have a higher dielectric constant and can store charge for longer periods of time.
Ferroelectric supercapacitors can be used in a variety of applications, including energy storage for portable electronic devices, electric vehicles, and renewable energy systems. They can also be used in memory devices and sensors.
Ferroelectric supercapacitors are typically manufactured using a thin film deposition technique, such as sputtering or chemical vapor deposition. This allows for precise control over the thickness and composition of the layers.
The advantages of ferroelectric supercapacitors include high energy density, fast charge-discharge cycles, and potential for use in a wide range of applications. However, they also have some limitations such as low voltage operation and limited temperature range. They are also more expensive to manufacture compared to regular supercapacitors.
