“…The excellent sodium storage behavior of N 0.2 S 0.8 ‐MC anode is mainly attributed to microdominant porous structure, the defects/disorders introduced by chemical doping, and the expanding interlayer distance caused by the N, S codoping. The former ensures the structure foundation, which builds an ideal bridge between the active electrode and electrolyte, and the latter contributes the component foundation, which enhances the sodium insertion/extraction and leading to a high capacity …”

Heteroatom doping is widely recognized as an appealing strategy to break the capacitance limitation of carbonaceous materials toward sodium storage. However, the concrete effects, especially for heteroatomic phase transformation, during the sodium storage reaction remain a confusing topic. Here, a novel hypercrosslinked polymerization approach is demonstrated to fabricate pyrrole/thiophene hypercrosslinked microporous copolymer and further give porous carbonaceous materials with accurately regulated N/S dual doping corresponding to starting feeding ratios. Significantly, the N doping contributes to the conductivity and surface wettability, while the S doping is bridged to build stable active sites, which can be electrochemically converted into mercaptan anions via faraday reaction and further enhancing reversible capacities. Meanwhile, the abundant S doping can also conduce to the expanded interlayer spacing to shorten the ions diffusion distance, thus optimizing the reaction kinetic. As a result, the N0.2S0.8‐micro‐dominant porous carbon delivers the highest reversible capacity of 521 mAh g−1 at 100 mA g−1 and excellent cyclic stability over 2000 cycles at 2000 mA g−1 with a capacity decay of 0.0145 mAh g−1 per cycle. This work is anticipated to provide an in‐depth understanding of capacitance contribution and illuminate the heteroatomic phase transformation during sodium storage reactions for doping carbonaceous anodes.

“…N-doped carbon sheets were also investigated by Yang et al to produce an anode delivering a capacity of 165 mA•h•g −1 after 600 cycles at current density of 200 mA•g −1 [204]. N/S co-doped ordered mesoporous carbon delivered a capacity of 419 mA•h•g −1 at 0.1 A•g −1 after 150 cycles, retaining 220 mA•h•g −1 at 5 A•g −1 even after 3000 cycles [205]. Although N-doping is most popular, doping with other elements such as B, O, S, and P are also of interest, and a review on the design, synthesis, and electrochemical properties of heteroatom-doped carbon anodes can be found in [206].…”

Sodium-ion batteries (SIBs) were investigated as recently as in the seventies. However, they have been overshadowed for decades, due to the success of lithium-ion batteries that demonstrated higher energy densities and longer cycle lives. Since then, the witness a re-emergence of the SIBs and renewed interest evidenced by an exponential increase of the publications devoted to them (about 9000 publications in 2019, more than 6000 in the first six months this year). This huge effort in research has led and is leading to an important and constant progress in the performance of the SIBs, which have conquered an industrial market and are now commercialized. This progress concerns all the elements of the batteries. We have already recently reviewed the salts and electrolytes, including solid electrolytes to build all-solid-state SIBs. The present review is then devoted to the electrode materials. For anodes, they include carbons, metal chalcogenide-based materials, intercalation-based and conversion reaction compounds (transition metal oxides and sulfides), intermetallic compounds serving as functional alloying elements. For cathodes, layered oxide materials, polyionic compounds, sulfates, pyrophosphates and Prussian blue analogs are reviewed. The electrode structuring is also discussed, as it impacts, importantly, the electrochemical performance. Attention is focused on the progress made in the last five years to report the state-of-the-art in the performance of the SIBs and justify the efforts of research.

Developing electrochemical energy storage devices with high energy-power densities, long cycling life, as well as low cost is of great significance. Sodium-ion capacitors (NICs), with Na + as carriers, are composed of a high capacity battery-type electrode and a high rate capacitive electrode. However, unlike their lithium-ion analogues, the research on NICs is still in its infancy. Rational material designs still need to be developed to meet the increasing requirements for NICs with superior energy-power performance and low cost. In the past few years, various materials have been explored to develop NICs with the merits of superior electrochemical performance, low cost, good stability, and environmental friendliness. Here, the material design strategies for sodium-ion capacitors are summarized, with focus on cathode materials, anode materials, and electrolytes. The challenges and opportunities ahead for the future research on materials for NICs are also proposed. www.advancedsciencenews.com www.small-journal.com to LICs, NICs are still in their infancy stage with many difficulties for their practical application. [23] For example, many battery-type electrode materials for lithium ion storage cannot meet the requirements of NIC devices due to the large size of Na + ions. In addition, due to the redox potential of Na/Na + is 0.3 V higher than that of Li/Li + , the working voltage ranges of NICs are expected to be a little narrower than LICs, which may influence the energy densities of NICs. Moreover, the electrolyte should provide a rapid migration process of Na + ions. Therefore, the rational material design will play crucial roles in the electrochemical performance improvement of NICs.So far, there are few papers which summarize the recent progress in NIC research area. In particular, the materials used in NICs, including anode, cathode, and electrolyte, have not been systematically reviewed. In this article, we focus on the latest advances in the cathode materials, anode materials, and electrolytes for NICs. First, we review the energy storage mechanism and demonstrate the configurations of NICs; then, we summarize the recent progress on electrode materials, including anode materials, cathode materials, as well as different electrolytes for NICs; finally, the challenges and future prospects for NIC research are proposed.
