“…Except for carbon modification and nanostructure design, heteroatom doping is also an effective strategy to boost electrochemical performance by adjusting the electronic/ionic states of the target, leading to enhanced adsorption ability, lower diffusion barrier, and improved intrinsic electronic/ionic conductivity in electrode materials (Figure 5c). [ 65,66 ] Numerous heteroatom doped carbonaceous materials have been applied as building blocks to construct heterostructures, in which the heteroatom provides additional active sites to bond with other building blocks, improving the electronic conductivity and structural durability of electrode materials. Nevertheless, heteroatom doped non‐carbon materials are rarely discussed in previous researches.…”

With the ever‐increasing adaption of large‐scale energy storage systems and electric devices, the energy storage capability of batteries and supercapacitors has faced increased demand and challenges. The electrodes of these devices have experienced radical change with the introduction of nano‐scale materials. As new generation materials, heterostructure materials have attracted increasing attention due to their unique interfaces, robust architectures, and synergistic effects, and thus, the ability to enhance the energy/power outputs as well as the lifespan of batteries. In this review, the recent progress in heterostructure from energy storage fields is summarized. Specifically, the fundamental natures of heterostructures, including charge redistribution, built‐in electric field, and associated energy storage mechanisms, are summarized and discussed in detail. Furthermore, various synthesis routes for heterostructures in energy storage fields are roundly reviewed, and their advantages and drawbacks are analyzed. The superiorities and current achievements of heterostructure materials in lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), lithium‐sulfur batteries (Li‐S batteries), supercapacitors, and other energy storage devices are discussed. Finally, the authors conclude with the current challenges and perspectives of the heterostructure materials for the fields of energy storage.

“…In our group, for the full cell study, we have used conventional CR2032‐type two‐electrodes coin cell and novel three‐electrodes cell. From the literature, we found that commonly used cathode materials for full cell were Prussian blue, layered metal oxides, polyanionic compounds, and organic materials [39,127–130] . Their counterpart anode materials were mainly carbonaceous materials, metallic alloy type materials, and others [6,131–137] .…”

Rechargeable lithium‐ion batteries (LIBs) have attained tremendous success and are extensively used in a wide range of fields. However, due to the scarcity and uneven geographical distribution of Li resources, its price is steadily increasing, which may limit its sustainable application in the near future. Potassium‐ion batteries (PIBs) are promising alternatives to LIBs owing to the earth abundance, low cost, and eco‐friendliness of potassium, and high energy density of PIBs. Although the field of PIBs has seen significant progress in the recent years, some challenges remain that limit their application, such as the severe side reactions between the electrolyte and electrodes, which result in an unstable solid electrolyte interphase, and thus, a low coulombic efficiency. Hence, designing suitable electrolytes is necessary for the development of PIBs. This review summarises the current developments in PIB electrolytes and comprehensively discusses electrolyte design strategies for four major classes of electrolytes, namely non‐aqueous, aqueous, ionic liquid, and solid‐state electrolytes. In addition, the effects of the properties of each class of electrolyte are discussed in detail. Furthermore, ionic liquid electrolytes, an emerging class of electrolytes, are discussed in detail with respect to PIBs. Finally, several critical issues, challenges, and prospects of PIB electrolytes are discussed, and an outlook for the future research direction of PIBs is presented.

[ 3 ] Therefore, it is urgent to develop novel generation EES devices, [ 4 ] such as sodium‐ion batteries (SIBs), [ 5 ] potassium‐ion batteries (PIBs), [ 6 ] zinc‐ion batteries (ZIBs), [ 7 ] magnesium‐ion batteries (MIBs), [ 8 ] calcium‐ion batteries (CIBs), [ 9 ] aluminum‐ion batteries (AIBs), [ 10 ] dual‐ion batteries (DIBs), [ 11 ] and solid‐state batteries (SSBs), [ 12 ] etc.…”

Rechargeable sodium/potassium‐ion batteries (SIBs/PIBs) with abundant reserves of Na/K and low cost have been a promising substitution to commercial lithium‐ion batteries. As for pivotal anode materials, metal sulfides (MSx) exhibit an inspiring potential due to the multitudinous redox storage mechanisms for SIBs/PIBs applications. Nevertheless, they still confront several bottlenecks, such as the low electrical conductivity, poor ionic diffusivity, sluggish interfacial/surface reaction kinetics, and severe volume expansion, which distinctly restrain the battery performance. Meanwhile, the systematic insights into the design strategies of MSx for SIBs/PIBs have been seldom elaborated. In this review, the energy storage mechanism, challenge, and design strategies of MSx for SIBs/PIBs are expounded to address the above predicaments. In particular, design strategies of MSx are highlighted from the aspects of morphology modifications involving 1D/2D/3D configurations, atomic‐level engineering containing heteroatom doping, vacancy creation, and interlayer spacing expansion, and MSx composites with other MSx, metal oxides, carbonaceous, and graphite materials to boost the comprehensive electrochemical performance of SIBs/PIBs. Furthermore, prospects are presented for the further advance of MSx to surmount imminent challenges, hoping to forecast feasible future orientations in this field.
