“…Various natural resources, such as biomass materials, crude oil, nature gas and coal, artificial polymer such as polyvinylidene chloride (PVDC), can be used as precursors for carbonaceous materials. There are various methodologies for converting carbonic precursors into carbonaceous materials, such as physical or chemical vapour deposition, pyrolytic heating as well as organic redox methodologies (Chmiola et al, 2010;Pekala, 1989;Conway et al, 1997;Maldonado-Hódar et al, 2000;Haddon, 2002;Lachawiec et al, 2005;Ji et al, 2009;Qin et al, 2009;Li et al, 2011;Lv et al, 2012;Liang, 2015;Morteza et al, 2015;Mousavi-Khoshdel and Targholi, 2015;Mousavi-Khoshdel et al, 2016;Ping et al, 2016;Wang and Pumera, 2016;Liu et al, 2017;Song et al, 2018;Silva et al, 2020;Kolosov and Glukhova, 2021a;Boulanger et al, 2021;Cao et al, 2021;Chen et al, 2021;Christians et al, 2021;Hoa et al, 2021;Nizam et al, 2021;Olabi et al, 2021;Ramirez et al, 2021;Zhai et al, 2021;Zhou et al, 2021;Yang et al, 2022b;Mei, 2022;Rashidi et al, 2022;Teimuri-Mofrad et al, 2022;Kolosov and Glukhova, 2021b;Song et al, 2021c;Vermisoglou et al, 2021;Tong et al, 2021;…”

“…On the other hand, doping of heteroatoms (e.g., O, N, F, S, B, P and metallic atoms into carbon skeleton will often adjust carbonaceous materials' wettability, electroconductibility and capacitance. As shown in Supplementary Figures S7, S8, those surface functionalization can be either derived from heteroatoms containing precursors or achieved through post-treatment/ activation process (Teimuri-Mofrad et al, 2022;Lachawiec et al, 2005;Maldonado-Hódar et al, 2000;Ji et al, 2009;Ramirez et al, 2021;Liu et al, 2017;Qin et al, 2009;Mei, 2022;Ping et al, 2016;Zhai et al, 2021;Hoa et al, 2021;Chen et al, 2021;Cao et al, 2021;Zhou et al, 2021;Wang and Pumera, 2016;Mousavi-Khoshdel et al, 2016;Mousavi-Khoshdel and Targholi, 2015;Silva et al, 2020;Song et al, 2018;Morteza et al, 2015;Kolosov and Glukhova, 2021a;Kolosov and Glukhova, 2021b;Song et al, 2021c;Vermisoglou et al, 2021;Tong et al, 2021;Chakrabarty et al, 2021;Liu et al, 2022;Paul1 and Roy, 2021;Basivi et al, 2021;Zhang et al, 2019;Zhai et al, 2011;Rashidi and Yusup, 2020;Yang and Zhou, 2017;Arango et al, 2018;Umezawa et al, 2021;Mandal et al, 2021;…”

Supercapacitors became more and more important recently in the area of energy storage and conversion. Their large power deliveries abilities, high stability and environmental friendliness characteristics draw tremendous attention in high-power applications such as public transit networks. Carbonaceous materials with unique surface and electrochemical properties were widely used in supercapacitors as electrode materials. This review focuses on the developments in supercapacitor electrodes made from carbonaceous materials recently, their working principle and evaluation parameters were summarized briefly. The preparation methods and electrochemical properties of different carbonaceous materials were compared and classified. It was found that the surface situation (e.g., porous structure, hydrophilic) of carbonaceous materials strongly affect the electrochemical performances of supercapacitor. So far, active carbons would be the most applicable carbonaceous electrode materials owing to their good chemical stability and conductivity, extensive accessibility inexpensiveness. But their energy densities still fall behind practical demands. Both theoretical calculations and experimental studies show that surface modification and doping of carbonaceous materials can not only optimize their pore size, structure, conductivity and surface properties, but also can introduce extra pseudocapacitance into these materials. Considering global environmental pollution and energy shortage problems nowadays, we sincerely suggested that future work should focus on domestic, medical and industrial wastes residues derived carbonaceous materials and scaled production process such as reactors and exhaust gas treatment.

“…Aerogel, the lightest solid in the world, provided merits such as high porosity, ultra-low density, and high specific surface area. In recent years, aerogels have been attracting wide attention in flexible/wearable electronic materials because the unique 3D structure of conductive aerogels can provide a conductive framework and can offer excellent electrical performance for flexible electronics such as piezoresistive sensors, − supercapacitors, − TENGs, − and other energy collection devices . The flexible aerogel with compressible 3D porous network structure will have more conductive paths in the aerogel under the effect of external pressure, so that the resistance of aerogel can be adjusted in real time.…”

Aerogels, due to their unique interconnected 3D networks, and large number of air-filled pores, extend the structural characteristics and physicochemical properties of the nanoscale to the macro level. However, aerogels made from a single component can hardly meet the needs of multifunctional energy harvesting/supply situations. Here, a BaTiO3-based hybrid aerogel (BTO HA) with 3D network structure was prepared. When the BTO HA is used as the electrode of triboelectric nanogenerator (BTO HA-TENG), high electrical output performances were obtained, which is due to the synergistic effect of solid–solid contact electrifications between the two electrification layers, the gas–solid contact electrifications between the inner surface of BTO HA and the air filled in the aerogel pores, and the piezoelectricity of the doped BaTiO3 nanoparticles. The BTO HA-TENG exhibited excellent fatigue resistance and structural stability after 12,000 cycles of alternatively contact/separation tests, and it can not only provide stable power supply for commercial capacitors, drive small mobile electronic devices but also can be used as a self-powered sensor to monitor human motion signals. Compared with traditional TENGs depending on surface charge transfer, the BTO HA-TENG exhibited its unique advantage that it can generate and transfer triboelectric charges by 3D volume, which boost TENGs’ electrical output performances.

Fast capture and stabilization of Li‐ions via physicochemical dual effects for an ultra‐stable self‐supporting Li metal anode

Lithium (Li) metal is regarded as one of the most promising anode candidates for next‐generation batteries due to its extremely high specific capacity and low redox potential. However, its application is still hindered by the uncontrolled growth of dendritic Li and huge volume fluctuation during cycles. To address these issues, flexible and self‐supporting three‐dimensional (3D) interlaced N‐doped carbon nanofibers (NCNFs) coated with uniformly distributed 2D ultrathin NiCo2S4 nanosheets (denoted CNCS) were designed to eliminate the intrinsic hotspots for Li deposition. Physicochemical dual effects of CNCS arise from limited surface Li diffusivity with a higher Li affinity, leading to uniform Li nucleation and less random accumulation of Li, as confirmed by ab initio molecular dynamics simulations. Due to the unique structure, exchange current density is reduced significantly and metallic Li is further contained within the interspace between the NCNF and NiCo2S4 nanosheets, preventing the formation of dendritic Li. The symmetric cell with a Li/CNCS composite anode shows a long‐running lifespan for almost 1200 h, with an exceptionally low and stable overpotential under 1 mA cm−2/1 mAh cm−2. A full cell coupled with a LiFePO4 cathode at a low N/P ratio of 2.45 shows typical voltage profiles but more significantly enhanced performance than that of a LiFePO4 cathode coupled with a bare Li anode.
