“…The same electrolyte formula is borrowed from lithium–sulfur battery electrolyte and modified for use in the sodium–sulfur system. Over 40% of sodium–sulfur battery studies report using TEGDME, making it the most commonly used ether‐based electrolyte solution (Figure g), and typically incorporating either 0.5–1.0 m sodium trifluoromethanesulfonate (NaOTf) or 1.5 m sodium perchlorate (NaClO 4 ) as the sodium salt (Figure g,h) 253a,255,258,261,272,273,279–281. On the other hand, almost half of the carbonate‐based electrolyte used in sodium–sulfur batteries feature a mixed solution of ethylene carbonate/propylene carbonate (EC/PC) at a 1:1 volume/volume ratio, which is also the most commonly used carbonate‐based electrolyte.…”

that makes use of intercalation materials as the electrodes (Figure 1), applications involving electric vehicles and smart grids may require rechargeable batteries with new battery chemistries that can generate even higher energy densities for longer driving ranges and higher energy-storage capabilities. [6][7][8] Additionally, the lithiated transition-metal oxides used in commercial lithium-ion battery cathodes tend to be expensive, scarce, or toxic to the environment. Thus, it is desirable to explore new electrode materials that are naturally abundant (and therefore less expensive) as well as environmentally compatible in order to successfully enter the future battery markets. [6,[8][9][10][11] This driving force has promoted the development of batteries with conversionreaction electrodes, in which reversible electrochemical reactions take place and new chemical compounds form during the cycling of the battery. Naturally abundant materials, such as sulfur for the cathode, can be applied as electrodes. Different metallic anodes have shown great potential in coupling with sulfur cathode to generate a high energy density, including lithium metal [3,10,[12][13][14][15][16][17]31] as well as other alkali [18][19][20][21][22][23][24]31] and high-valent metals. [18,[25][26][27][28][29][30][31] As a next-generation energy-storage technology beyond lithium-ion batteries, lithium-sulfur batteries are the most promising low-cost, high-capacity energy-storage device available due to their high charge-storage capacity, low cost, and the wide availability of sulfur. [32][33][34][35] The electrochemical reactions of lithium-sulfur batteries involve reversible conversions between sulfur (S 8 ), lithium polysulfides (Li 2 S x , x = 4-8), and lithium sulfides (Li 2 S 2 and Li 2 S). [33][34][35][36] The conversions between sulfur and lithium polysulfides and lithium sulfides involve phase changes between liquid-state polysulfides and solid-state sulfur and sulfides. [35][36][37][38][39][40] Thus, the conversion reaction of lithium-sulfur battery chemistry has no restriction in maintaining the initial crystal chemistry of the electrode during electrochemical cycling. [39][40][41][42] Therefore, a full twoelectron redox reaction per sulfur atom can occur in a manner that is both reversible and stable, increasing the chargestorage capacity drastically as compared to the currently used insertion-reaction oxide cathodes. [7,[39][40][41][42] As a result, sulfur cathodes possess a high theoretical charge-storage capacity of 1672 mA h g −1 , which is the highest value among solid-state Lithium-sulfur batteries are a major focus of academic and industrial energystorage research due to their high theoretical energy density and the use of low-cost materials. The high energy density results from the conversion mechanism that lithium-sulfur cells utilize. The sulfur cathode, being naturally abundant and environmentally friendly, makes lithium-sulfur batteries a potential next-generation energy-storage technology. The current state of the rese...

The recent advances of the lithium-ion battery concept towards the development of sustainable energy storage systems are herein presented. The study reports on new lithium-ion cells, developed over the last few years with the aim of improving the performance and sustainability of the electrochemical energy storage. Alternative chemistries, involving anode, cathode and electrolyte components, are herein recalled in order to provide an overview of state of the art lithium-ion battery systems, with particular care on the cell configurations currently proposed at the laboratory-scale level. Hence, the review highlights the main issues related to full cell assembly, which have been tentatively addressed by limited number of reports, while many recent papers describe material investigation in half-cells, i.e., employing lithium metal anode. The new battery prototypes here described are evaluated in terms of electrochemical performances, cell balance, efficiency and cycling life. Finally, the applicability of these suitable energy storage systems is evaluated in the light of their most promising characteristics, thus outlining a conceivable scenario of new generation, sustainable lithium-ion batteries.

“…Although this ceramic separator could inhibit the shuttling of polysulfide, the battery still experienced a continuous decay of capacity . In contrast, when using another NaCF 3 SO 3 /TEGDME electrolyte in a similar battery configuration, a much more stable cycling performance up to 100 cycles was obtained with an initial and final discharge capacity of 855 and 521 mAh g −1 , respectively, which indicates the good potential of this type of separator when coupled with suitable electrolytes.…”

Nonlithium Metal–Sulfur Batteries: Steps Toward a Leap

progress in battery technology has been primarily driven by the specific demands of various applications. In the current era, a higher gravimetric/volumetric energy density is still an ever-growing requirement to power mobile electronics and extend the driving range of electric vehicles (EVs) with increased energy consumption. Meanwhile, the exploration and utilization of the various forms of renewable energy, such as wind, tidal, and solar energy, which are normally harvested as electricity but fluctuate greatly over time, require them to be stored, regulated, and then delivered for practical application. [1,2] As a result, these two issues impose high urgency and great necessity on the development of suitable battery systems to meet these demands, in particular, energy density, safety, and cost effectiveness. [3][4][5] At this stage, the most successfully commercialized secondary batteries are the LIBs, which have been widely applied in a variety of devices, including mobile phones, power tools, and electric vehicles. In an LIB, electricity is stored and released based on the reversible insertion-extraction of Li ions in the electrode materials. [6] The second-generation LIBs, which are based on layered LiNi x Mn y Co z O 2 (NMC) or LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) cathode materials and graphite anode materials, normally have practical gravimetric/volumetric energy densities as high as 180-220 Wh kg −1 and have been applied in the latest electric vehicles (e.g., the Tesla Model S car) (Figure 1). Present mobile devices, transportation tools, and renewable energy technologies are more dependent on newly developed battery chemistries than ever before. Intrinsic properties, such as safety, high energy density, and cheapness, are the main objectives of rechargeable batteries that have driven their overall technological progress over the past several decades. Unfortunately, it is extremely hard to achieve all these merits simultaneously at present. Alternatively, exploration of the most suitable batteries to meet the specific requirements of an individual application tends to be a more reasonable and easier choice now and in the near future. Based on this concept, here, a range of promising alternatives to lithium-sulfur batteries that are constructed with non-Li metal anodes (e.g., Na, K, Mg, Ca, and Al) and sulfur cathodes are discussed. The systems governed by these new chemistries offer high versatility in meeting the specific requirements of various applications, which is directly linked with the broad choice in battery chemistries, materials, and systems. Herein, the operating principles, materials, and remaining issues for each targeted battery characteristics are comprehensively reviewed. By doing so, it is hoped that their design strategies are illustrated and light is shed on the future exploration of new metal-sulfur batteries and advanced materials.
