Why is it said that supercapacitors can replace batteries? 1

A supercapacitor, also known as an ultracapacitor or electrochemical double-layer capacitor, is an electronic device capable of storing and releasing large amounts of electrical energy. Unlike traditional batteries, supercapacitors store energy primarily through the adsorption and desorption of charges on electrode surfaces and the double-layer capacitance effect, rather than through electrochemical reactions.

The difference between supercapacitors and traditional batteries like the DSP56F801FA80E lies in their energy storage principles and structural design. Traditional batteries store electrical energy through chemical reactions, which cause chemical changes during charging and discharging, thereby limiting their charge/discharge speed and cycle life. In contrast, supercapacitors achieve rapid charge/discharge speeds, high power density, and long cycle life by utilizing the adsorption of positive and negative charges on electrode surfaces in electrolyte solutions and the formation of double-layer capacitance.diode

The structure of a supercapacitor typically consists of two electrodes made of materials such as activated carbon, with an electrolyte sandwiched between them. The electrodes are specially treated to form a porous structure with an enormous surface area, which helps increase the electrode surface area and thereby enhances the capacitor's energy storage capacity. The electrolyte serves to conduct electricity and separate positive and negative charges, ensuring the proper functioning of the capacitor.diode
