“…Besides, as revealed by the SEM image of the surface of LLZO-embedded PEO coating layer ( Figure S10c,d, Supporting Information), the macropores of the pristine PI separator have been filled with rigid-flexible composites of LLZO and PEO mixtures, which could further prevent the in situ formed copper sulfides from migrating to anode side. [2,31,32] However, the notorious polysulfide shuttling effects and the sluggish S/MgS conversion severely imped their developments. Nevertheless, the relative content of copper element is only ≈0.25% detected by energy dispersive X-ray spectroscopy (EDS) results even after 100 cycles.…”

Rechargeable metal–sulfur batteries encounter severe safety hazards and fast capacity decay, caused by the flammable and shrinkable separator and unwanted polysulfide dissolution under elevated temperatures. Herein, a multifunctional Janus separator is designed by integrating temperature endurable electrospinning polyimide nonwovens with a copper nanowire‐graphene nanosheet functional layer and a rigid lithium lanthanum zirconium oxide‐polyethylene oxide matrix. Such architecture offers multifold advantages: i) intrinsically high dimensional stability and flame‐retardant capability, ii) excellent electrolyte wettability and effective metal dendritic growth inhibition, and iii) powerful physical blockage/chemical anchoring capability for the shuttled polysulfides. As a consequence, the as constructed lithium–sulfur battery using a pure sulfur cathode displays an outstandingly high discharge capacity of 1402.1 mAh g−1 and a record high cycling stability (approximately average 0.24% capacity decay per cycle within 300 cycles) at 80 °C, outperforming the state‐of‐the‐art results in the literature. Promisingly, a high sulfur mass loading of ≈3.0 mg cm−2 and a record low electrolyte/sulfur ratio of 6.0 are achieved. This functional separator also performs well for a high temperature magnesium–sulfur battery. This work demonstrates a new concept for high performance metal–sulfur battery design and promises safe and durable operation of the next generation energy storage systems.

“…However, the use of lithium‐metal anode may soon be a problem due to the limited availability of lithium sources and the expected increase in price . Based on the development and progress achieved with lithium–sulfur batteries, researchers have explored a broad range of conversion‐type battery electrochemistries coupling the high‐capacity sulfur cathode with other metallic anodes, such as sodium, potassium, magnesium, calcium, and aluminum . Various room‐temperature metal–sulfur batteries have attracted extensive interest because of their advantages, which are very similar to lithium–sulfur batteries, including high theoretical capacity, high elemental abundance, and low cost .…”

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...

“…With the consumption of fossil fuel, energy exhaustion and environmental pollution have become a serious social problem. Economy friendly and sustainable energy storage systems that can utilize and integrate renewable but intermittent energy sources, such as solar, wind, and geothermal energy, into electric grids are of prime importance . Secondary batteries are considered as promising and important carriers to store and deliver these energies due to their efficiency and portability.…”

Potassium‐ion batteries (PIBs) as a promising supplement to lithium‐ion batteries have drawn great attention attributing to the abundant potassium resources, the fast‐ionic conductivity of potassium ions in electrolyte, and the low standard redox potential of potassium. However, the development of PIBs is still in its infancy, which is largely restricted by the fact that the electrode materials, especially the cathode materials of PIBs, are far from satisfactory in practical applications regarding the capacity, voltage, and cycle life. Therefore, most of current research efforts have been devoted to exploring new and high‐performance electrode materials for achieving PIBs with high capacity and voltage as well as excellent cyclability. In this review, the recent advancements on cathode materials for PIBs are specially summarized. Besides, technological developments, scientific challenges, and future research opportunities of cathode materials for PIBs are also briefly outlooked.
