“…Heteroatom doping, that is, applying nonmetal atoms, like nitrogen, phosphorus, sulfur, fluorine, and boron, or metal atoms, like iron, gold, silver, and cobalt, has attracted enormous attention to modify the carbon materials, which can effectively improve the electrode materials’ charge-storage capability due to the difference in electronegativity and atom size. − Heteroatoms could change the electronic and crystalline structures of the carbon materials, enhancing the chemical stability, electrical conductivity, and electron-donor properties. , Kim et al prepared nitrogen-doped and nitrogen/sulfur-codoped microporous carbon materials using a carbonyl-based aromatic porous polymer after amine functionalization or chemical impregnation. The carbon materials had high specific capacitances because of the heteroatom doping …”

For the purpose of assembling high-performance solid-state hybrid supercapacitors (HSCs) with superior cycling stability and energy density, biomass-derived multi-heteroatom-doped carbon materials were prepared in this work and utilized as negative electrodes for the supercapacitors. The applied biomass in this study included orange peel and egg white; besides, we also prepared Ag-doped egg white as a precursor through a denaturation reaction to synthesize a Ag-nanoparticle-decorated carbon material; the consequently obtained carbon materials were referred to as OC, EC, and Ag–EC, respectively. The as-synthesized heteroatom-doped carbon materials displayed excellent electrochemical performance. The specific capacitance retentions were 101.7, 105.4, and 107.4% for OC, EC, and Ag–EC, respectively, after 50 000 cycles. In addition, a core–shell structured C/N–CoO@CoO/NiO nanomaterial was also synthesized and used as the positive electrode, which exhibited a high cycling stability of 111.6% after cycling for 50 000 times. The three corresponding solid-state hybrid supercapacitors (HSCs) possessed excellent energy densities of 33.1, 30.1, and 35.6 Wh kg–1 at about 850.0 W kg–1, respectively. After cycling for 50 000 times, their specific capacitance retentions were 145.9, 139.2, and 140.0%, respectively.

Numerous challenges, like the uninterrupted supply of electricity, stable and reliable power, and energy storage during non‐operational hours, arise across various industries due to the absence of advanced energy storage technologies. With the continual technological advancements in portable electronics, green energy, and transportation, there are inherent limitations in their innovative production. Thus, ongoing research is focused on pursuing sustainable energy storage technologies. An emerging solution lies in the development of asymmetric supercapacitors (ASCs), which offer the potential to extend their operational voltage limit beyond the thermodynamic breakdown voltage range of electrolytes. This is achieved by employing two distinct electrode materials, presenting an effective solution to the energy storage limitations faced by ASCs. The current review concentrates on the progression of working materials to develop authentic pseudocapacitive energy storage systems (ESS). Also, evaluates their ability to exceed energy storage constraints. It provides insights into fundamental energy storage mechanisms, performance evaluation methodologies, and recent advancements in electrode material strategies. The review approaches developing high‐performance electrode materials and achieving efficient ASC types. It delves into critical aspects for enhancing the energy density of ASCs, presenting debates and prospects, thereby offering a comprehensive understanding and design principles for next‐generation ASCs in diverse applications.
