“…5 Furthermore, N-doping enhances the specific capacitance of the carbon materials by reducing the capacitance fading and volume expansion. 6 The thermal treatment, for example, pyrolysis, is a widely applied strategy for the synthesis of N-enriched carbon materials (NCM), many studies were conducted to produce NCM for energy storage applications via the thermal treatment of N-rich biomass such as macroalgae, [7][8][9] expired milk, 10,11 and bean pulp. 12,13 However, the synthesis of NCM from N-poor feedstock requires the incorporation of N into the carbon structure from an external N precursor, for example, melamine, chitosan, and urea (U).…”

The thermal treatment of an activated carbon/chars with a nitrogen precursor is not a sustainable nor an efficient method for the incorporation of N into the carbon structure. This study proposes the use of hydrothermal carbonization (HTC) as an environmentally friendly method for the incorporation of N into the bulk of carbon materials. The authors propose the following sequence for the synthesis of Nenriched carbon materials (NCM) for energy storage applications: HTC of the N precursor and biomass ! activation of N-hydrochar (N-HC). To investigate the proposed method, HTCs of spent coffee grounds (SCG) with N precursors (urea and alanine) were conducted at 220 C for 5 hours. The resulted N-HCs were subjected to a mild thermal activation via pyrolysis at 600 C for 2 hours. The results showed that HTC enhances the incorporation of N into the carbon matrix via many reactions, for example, the Maillard reaction (MR) or the Mannich reaction, which may accompany the formation of HC via the solved-intermediate pathway or the solid-to-solid pathway, respectively. However, adjusting some parameters before HTC, for example, the concentration of the N precursor and the pH value of the slurry is important to avoid a significant reduction in the N-HC yield. The proposed method led to the synthesis of NCM with a N content of 10.3wt% The X-ray photoelectron spectroscopy (XPS) confirmed the incorporation of N into the bulk of NCM and showed a significant increase in the content of heterocyclic N compounds (pyridinic N, pyrrolic N, and graphitic N) in the NCM. The incorporation of N via the proposed method significantly improved the electrochemical properties of NCM as the values of the specific capacitance and the electrical conductivity in the NCM increased by five times and four times, respectively.

Reasonable porous structure and proper heteroatom doping have great influences on electrode materials for supercapacitors. Herein, O, N, and P codoped hierarchical porous carbon (ONPC) was synthesized through a one-pot carbonization−activation strategy by using chitosan as the carbon precursor, phosphoric acid as the activator, and melamine foam as the skeleton. The use of melamine foam facilitated the formation of an interconnected carbon framework and introduced more nitrogen functional groups. Owing to the hierarchical pore structure, large surface area (1588 m 2 g −1 ), and significant heteroatom contents of O (8.61%), N (7.95%), and P (1.34%) in the carbon matrix, the 700 °C carbonized sample ONPC-700 had a specific capacitance of 230 F g −1 at 0.2 A g −1 . A high energy density of 7.5 Wh kg −1 at 100 W kg −1 was achieved for the supercapacitor fabricated with two identical ONPC-700 electrodes. Furthermore, the capacitance retention of the device was evaluated to be as high as 86.53% after 8000 cycles.

“…Besides, improvement has also been found in expired milk that consists of casein and serum, which act as a natural source for doping agents of nitrogen and sulfur atom. Specifically, Dat et al [ 79 ] reported that the highest N and S elements of 2.09% and 0.81%, respectively, are capable to increase the specific capacitance up to 186.3 F/g. Table 3 summarizes the food waste–based activated biochar as electrode materials in a supercapacitor for the energy storage application.…”

The abundance of food waste across the globe has called for the mitigation and reduction of these discarded wastes. Herein, the potential of biochar derived from food waste is unquestionable as it provides a sustainable way of utilizing the abundance of available biomass, as well as an effective way of preserving the ecosystem through the reduction of concerning environmental issues. This review focuses on the food waste–based biochar as advanced electrode materials in the energy storage devices. Efforts have been made to present and discuss the current exploration of the food waste utilization, along with the biochar production technologies through thermochemical conversion, including combustion, gasification, and pyrolysis method. Finding its limitation in literatures, discussion on the food waste–based biochar fabrication method as the electrode materials is elaborated, alongside the current food waste–based biochar that has been explored in the energy application thus far. Towards the end, the outlook and perspective on the further development of food waste–based biochar have been outlined.
