In scientific terms, it is called an electrochemical capacitor to distinguish it from the conventional electrostatic or electrolytic capacitors.

- the advantage of showing high storage capacity it has many problems such as the disadvantage of being difficult to use in mass production because the material is expensive. Therefore, in order to improve the energy density and power density of the supercapacitor, it is urgent to develop an electrode having high porosity and electrical conductivity, which is inexpensive and has high electrical conductivity.

- MOFs metal-organic frameworks
- the hybrid complex is applied in various fields, such as a catalyst for water purification, an anticancer agent, an immunodeficiency virus treatment, a treatment for fungal and bacterial infections, a treatment for malaria, various drug delivery materials, photocatalysts, sensors, and aerospace materials, in addition to supercapacitors or secondary batteries. As this is possible, it can be used as a commercially very useful material.
