“…When used as SIB anode, superior rate performance (112 mAh g −1 at 8 A g −1 ) and ultralong cycle life (116 mAh g −1 at 4 A g −1 after 3000 cycles) were demonstrated owing to the open skeleton structure of the 3DHCM material. Sodium carboxymethylcellulose (CMC), because of its richness in C, H, and O elements, was first utilized with silica templates to prepare oxygen‐rich porous carbon (OPC) . Its richness in carboxymethyl and hydroxyl groups, as well as its water solubility and viscosity, guarantees a homogeneous mixture with silica template and accounts for the successful preparation of OPC.…”

tunable porous structures, various morphologies, and high electron conductivity, which makes them very attractive in many different fields of applications, such as energy storage, absorption, water filtration, drug delivery, catalysis, and sensing. [3] Their unique properties can be utilized in various kinds of templates, substrates, capsules, and decorations, especially in energy storage research fields. [4] Due to global concerns about greenhouse gas emissions from the fossil fuels and climate change, many renewable energy technologies have been extensively developed and investigated to alleviate the reliance on the traditional fossil energy sources. [5] In order to store the intermittent forms of energy such as wind energy and solar energy, rechargeable batteries are widely considered as one of the best types of power storage for large-scale electrical energy storage systems (EESs). [6][7][8] In the past few decades, lithium-ion batteries (LIBs) have dominated the power source markets for advanced electric vehicles and portable electronics, since they possess the obvious advantages of high energy density and long cycle life. [9] Nevertheless, the low abundance, uneven distribution, and high price of lithium are increasingly hindering its application in the energy storage area. [10] Sodium-ion batteries (SIBs), which share a similar electrochemical nature, have been considered as the most promising low-cost alternative candidates to the commercial LIBs, especially for the EESs and smart grid applications, owing to the high abundance of sodium sources worldwide. [11,12] Considerable efforts and progress have been made toward transferring the successful experience on the LIB system to SIBs, especially in terms of electrode materials. Both the anode and cathode materials suffer, however, from sluggish reaction kinetics, lower specific capacity, and less electrochemical activity because of the large ionic radius of Na + (1.02 Å for Na + vs 0.76 Å for Li + ). [13,14] Furthermore, graphitic carbon is almost electrochemically inactive in SIBs. Therefore, developing desirable electrode materials for high performance SIBs, especially desirable anode materials, is still an urgent task that is necessary for the real application of SIBs. [15][16][17][18] Unlike the intercalation-type materials, most of the anode materials for SIBs store Na + ions through alloying reactions Over the past decades, porous carbonaceous and carbon-incorporated composites have aroused tremendous attention owing to their unique properties such as high surface area, excellent accessibility to active sites, tunable morphologies and structures, and superior mass transport and diffusion. They have been widely investigated and applied in various fields, such as energy storage, absorption, water filtration, drug delivery, catalysis, and sensing. In the energy storage area, rechargeable sodium-ion batteries (SIBs) have attracted tremendous attention as the next-generation power plants for large-scale energy storage systems (EESs). However, their low ene...

Rhombic Dodecahedron ZIF‐8 Precursor: Designing Porous N‐Doped Carbon for Sodium‐Ion Batteries

The design and synthetic strategy of nanostructure electrodes are crucial in the rapid development of sodium‐ion batteries for energy storage device. Rhombic dodecahedral N‐doped carbon with a porous structure has been prepared by using ZIF‐8 as the precursor, which could be beneficial for electrolyte permeation as well as electron and ion transportation. The nitrogen content and surface structure can be adjusted by controlling the heating temperature. As an anode for sodium‐ion batteries, the as‐derived porous N‐doped carbon with a rhombic dodecahedral structure demonstrates a very high reversible capacity above 300 mA h g−1 after 500 cycles at a current density of 0.5 A g−1, as well as a good cycle stability and excellent rate capability, which could make it an excellent candidate for sodium‐ion batteries with high performance. Additionally, the as‐assembled full cell, using Prussian blue as the cathode, displays a capacity of 76 mA h g−1 at 0.1 A g−1 after 50 cycles. In this way, this work will expand the application of metal‐organic frameworks and their derivatives in large‐scale electric energy storage.

Most of the porous carbons synthesized by complex templated methods using NaCl, , calcium carbonate, silica, , and polystyrene are reported. These studies suggest the requirement of a simple and effective approach to prepare mesoporous carbon.…”

Sucrose–Thiourea-Derived Nitrogen and Sulfur Co-doped Hierarchically Porous Carbon Nanosheets as a High-Performance Negative Electrode for Sodium-Ion Batteries

Nitrogen-containing porous carbon derived from sucrose and thiourea by an environmentally friendly and economically feasible technique has been explored as a negative electrode for sodium-ion batteries (SIBs). Aforesaid sucrose−thiourea-derived carbon (STU) contains micro-, meso-, and macroporous particles with a significant surface area of 2070 m 2 /g. When examined as an negative electrode in SIB applications, STU delivers an appreciable electrochemical performance upon moderate-rate (50 mA/g) and high-rate (1.6 A/g) charge conditions. A steady-state progressive capacity of 285 mAh/g is observed at 50 mA/g after 100 cycles. Further, an STU negative electrode delivers an appreciable capacity of 216 mAh/g after 600 cycles with 77% capacity retention. Furthermore, a high reversible capacity of 132 mAh/g was obtained at 1.6 A/g after 230 cycles. The excellent electrochemical activity of an STU negative electrode for SIB application is believed to be due to the presence of a combination of micro-, meso-, and macropores along with a high surface area and more edges and defect sites of carbon.
