For this, a comparison of compositional and electrochemical properties present in the carbons obtained of albedo, flavedo, and the complete orange peel was carried out. e morphology and composition of carbons obtained were analyzed by Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray (EDX), X-Ray Diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR). e synthetized carbons were not subjected to the activation process by chemical compounds to relate only the properties of orange peel parts with their electrochemical behaviour. All samples were tested by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). e carbon obtained of albedo presented a superior specific capacitance (210F/g) of the rest samples. e value of albedo-based carbon capacitance is comparable with works presented in the literature that used a whole orange peel with chemical activators. In this way, it is possible to obtain large capacitances using only a part of orange peel (albedo). us, the importance of this study is that the albedo can be proposed as a material applied to electrodes for super- capacitors while the flavedo can be used in food industry or for oil extraction. 1. Introduction A big percent of electricity generation in the world depends on fossil fuels. In Mexico, the power plants based on fossil fuels reached 79% of all installed plants in 2019 [1]. However, due to the depletion of fossil fuels, the countries are trying to deliver electricity based on other types of generation. So, the incorporation of alternative energies such as wind, solar, and hydrogen energy has been proposed to be incorporated on microgrids and grids of the electric industry. Even though the alternative energies are a good option, these have a random behavior that requires devices that store energy when it is excessive and deliver it when is necessary. e Energy Storage Systems (ESSs) mostly used are the batteries and supercapacitors [2]. e supercapacitor has the advantage of long cycle life and low cost, and its operation does not cause pollution [2]. Energy storage in supercapacitors is carried out using electrostatic charge accumulation or employing faradic re- actions of electroactive species [3]. ese devices are con- stituted by two electrodes (anode and cathode), an electrolyte, and a separator to isolate the electrodes [4]. Electrodes for supercapacitors based on activated carbon have been proposed due to their good electrical properties Hindawi Journal of Chemistry Volume 2021, Article ID 3022815, 9 pages https://doi.org/10.1155/2021/3022815
