Nano supercapacitors and piezoelectric effect or electric pressure effect
Researcher and author: Dr. ( Afshin Rashid)
Note: One of the unusual features that some ( nano supercapacitors) show is the piezoelectric phenomenon or the effect of electric pressure . By applying an external force, the dipoles of these ( nano supercapacitors) are stimulated and an electric field is created. Reversing the effect of the force (eg from tensile to compressive) reverses the direction of the field.
In ( nano-supercapacitors) the production of electricity with the help of pressure force is called the piezoelectric state ( nano-supercapacitors) . Also, the ability to convert mechanical pressure and electricity into each other is called "piezoelectric property" in ( nano-supercapacitors) . The definition of piezoelectricity or piezoelectricity in ( nano-supercapacitors) is the production of electricity created by polarization by a nano-electrode due to the application of stress in ( nano-supercapacitors) when an electric field is applied to a piezoelectric nano-electrode, it is subjected to strain. which is called reverse piezoelectric behavior in ( nano supercapacitors) .A necessary condition for being piezoelectric ( nano-supercapacitors) is the absence of central symmetry in the structure ( nano-supercapacitors) .
In the structure (nano-supercapacitors), the nanomaterial used is a type of nano-scale material that is used as building blocks in the fields of physics and electronics, while supercapacitors due to their high performance and high energy concentration Speed replaces conventional capacitors. The nanomaterial supercapacitor is an electrochemical electronic device (capacitor) that has the ability to increase the storage level of static electrons by increasing the amount of energy. Due to the structure made of nanotubes, it can expand. Anodes and cathodes, like conventional capacitors, are separated by insulating materials, also known as dielectrics. The overall performance of a nanomaterial supercapacitor depends on the materials used to make it and the properties of the electrodes. Energy storage that includes (nano supercapacitors) , occupies a middle ground between double-layer electrolytic capacitors, which store energy simply in two layers on a high-surface-area conductor, and batteries, which rely primarily on Faraday electron transport to (usually) metal centers. It is possible by combining charge compensating ions .
Conclusion :
One of the unusual features that some ( nano supercapacitors) show is the piezoelectric phenomenon or electric pressure effect . By applying an external force, the dipoles of these ( nano supercapacitors) are stimulated and an electric field is created. Reversing the effect of the force (eg from tensile to compressive) reverses the direction of the field.
