“…Cycling the cell at 0.5 C provided a steady discharge capacity of greater than 160 mA h g −1 after 100 cycles, comparable to the capacity obtained in a lithium cell. The large charging capacity in the first cycle and the poor coulombic efficiency is attributed to the incompatibility of carbonate‐based electrolytes with sodium‐metal deposition, which leads to increased resistance in the cell, as observed by PEIS (Figure S30) . To obtain the same results achieved in the lithium cell, each of the components of the sodium coin cell would require further optimization.…”

Developing cathodes that can support high charge–discharge rates would improve the power density of lithium‐ion batteries. Herein, the development of high‐power cathodes without sacrificing energy density is reported. N,N′‐diphenylphenazine was identified as a promising charge‐storage center by electrochemical studies due to its reversible, fast electron transfer at high potentials. By incorporating the phenazine redox units in a cross‐linked network, a high‐capacity (223 mA h g−1), high‐voltage (3.45 V vs. Li/Li+) cathode material was achieved. Optimized cross‐linked materials are able to deliver reversible capacities as high as 220 mA h g−1 at 120 C with minimal degradation over 1000 cycles. The work presented herein highlights the fast ionic transport and rate capabilities of amorphous organic materials and demonstrates their potential as materials with high energy and power density for next‐generation electrical energy‐storage technologies.

“…A recent paper from Tarascon's group [ 24 ] explored the effect of various NaPF 6 ‐based electrolytes containing either single linear carbonates DMC, EMC, DEC, or single cyclic carbonates PC, EC, on the stability of the SEI formed in full Na 3 V 2 (PO 4 ) 2 F 3 (NVPF) or Na 3 V 2 (PO 4 ) 3 (NVP)/HC cells via complementary in‐situ UV–Vis spectroscopy and in situ cyclic voltammetry (CV) measurements together with galvanostatic charge–discharge tests. In this case, only full cell systems were investigated to avoid any influence of the sodium metal counter electrode.…”

technologies. Unlike lithium, whose market is already very tight, sodium mineral deposits are almost infinite, evenly distributed worldwide, much easier to extract and thereby attainable at low cost. [1][2][3][4] If the realization of Na-rechargeable batteries could be practically possible, there will be nearly three orders of magnitude relaxation in the constraints on lithium-based resources, accompanied by sustainability, improved environmental benevolence, and cost reduction ( Table 1). Even more appealing is the possible use of the widely available and lighter aluminum, rather than copper, as negative current collector and hard carbon from renewable sources instead of graphite for the negative electrode. Finally, the stability of sodium-ion batteries (SIBs) in the fully discharged state would significantly enhance the safety associated with the shipment of large-format SIBs worldwide.These beneficial features of sodiumbased cells revived the research work on Na-based rechargeable batteries and accordingly captured the attention of both the academic research and industry sectors. However, similar to LIB, most of the research work in Na-based batteries have focused on the development and elaboration of negative and positive For sodium (Na)-rechargeable batteries to compete, and go beyond the currently prevailing Li-ion technologies, mastering the chemistry and accompanying phenomena is of supreme importance. Among the crucial components of the battery system, the electrolyte, which bridges the highly polarized positive and negative electrode materials, is arguably the most critical and indispensable of all. The electrolyte dictates the interfacial chemistry of the battery and the overall performance, having an influence over the practical capacity, rate capability (power), chemical/thermal stress (safety), and lifetime. In-depth knowledge of electrolyte properties provides invaluable information to improve the design, assembly, and operation of the battery. Thus, the full-scale appraisal of both tailored electrolytes and the concomitant interphases generated at the electrodes need to be prioritized. The deployment of large-format Na-based rechargeable batteries also necessitates systematic evaluation and detailed appraisal of the safety-related hazards of Na-based batteries. Hence, this review presents a comprehensive account of the progress, status, and prospect of various Na + -ion electrolytes, including solvents, salts and additives, their interphases and potential hazards.

to peak shift operation since the electric energy output from solar and wind energy is not stable. [1][2][3] Electrochemical energy storage technologies representative of lithium-ion batteries (LIBs) are expected to play a critical role because of their high energy density and energy conversion efficiency. [4,5] Recently, research on sodium-ion batteries (SIBs) has been motivated and expected to be better than lithium-ion batteries for the applications on large-scale energy storage because of their advantages on similarity with LIBs and much lower cost. [6,7] In a typical SIB, two electrodes (cathode and anode) and electrolyte are three necessary internal components, as illustrated in Figure 1a. In general, the electrolytes for SIBs can be classified into liquid nonaqueous electrolyte, aqueous electrolyte, gel polymer electrolyte mainly composed of liquid nonaqueous components, and solid electrolyte (including both inorganic and polymer electrolytes). In comparison with liquid nonaqueous and gel polymer electrolytes, aqueous and solid electrolytes (especially inorganic solid electrolyte) are intrinsically safer, and some reviews have been published recently. [8][9][10] From the cost and compatibilities with manufacturing equipment points of view, the SIBs using the nonaqueous electrolytes are believed to be preferential to those using other electrolytes. A typical electrolyte for SIBs is composed of sodium salts, flammable organic carbonate or ether solvents, and/or some functional additives. In conventional SIBs using nonaqueous electrolyte, as a sole liquid component, the electrolyte can infiltrate every vacant space in the inner of the battery. The electrolyte takes part in the buildup of solid electrolyte interphase (SEI) on the anode surface and cathode electrolyte interphase (CEI) by the electrochemical reactions between the electrolyte and anode/cathode electrodes. Therefore, the electrolyte strongly affects the SEI and CEI interphase properties, and further affects the cell performance and safety characteristics of SIBs.Safety concerns of LIBs have attracted much attention, especially in the electric vehicles (EVs) applications of largescale power batteries. In the energy storage stations, there are hundreds of the high-energy batteries. A safety accident in a large-scale energy storage station could trigger a disastrous consequence with a huge economic loss. Therefore, safety characteristics of SIBs are critical for their applications in the energy storage fields. Similar with the safety concerns of LIBs, [11] the safety of SIBs is also tightly related with active Rapidly developed Na-ion batteries are highly attractive for grid energy storage. Nevertheless, the safety issues of Na-ion batteries are still a bottleneck for large-scale applications. Similar to Li-ion batteries (LIBs), the safety of Na-ion batteries is considered to be tightly associated with the electrolyte and electrode/electrolyte interphase. Although the knowledge obtained from LIBs is helpful, designing safe electrolytes and obtaining ...
