“…morphology, while 2D materials mainly refer to the sheet like morphology. [196,[260][261][262][263] From the perspective of transport kinetics, although both of 1D and 2D materials have their own advantages, however, the limitation of 1D transport dimensions and self-stacking issue of 2D materials would inevitably weaken the reaction kinetics, especially for the thick electrode with high mass load. [78,[264][265] To beyond that, the construction of hierarchical 3D cathode materials with efficient transport kinetics is desirable, and their fabrication can be usually realized by either based on the rational combination of 0D and/or 1D and/or 2D materials, or directly using template methods.…”

have also greatly aroused the positive exploration of alternative LIB technologies in recent years. [44] In contrast to the flammable organic electrolyte in LIBs, the aqueous one exhibits lower cost, higher safety, and especially the superior ionic conductivity, which is generally two orders of magnitude higher than that of the organic system. [9,10] All those unparalleled advantages would make the aqueous battery technologies to be the promising candidates in the future. [11] Rechargeable aqueous zinc-ion batteries (AZIBs), which is mainly composed of zinc metal anode, zinc salt-based aqueous electrolyte, and Zn 2+ host cathode, hold the great promise for energy storage applications in very recent years. [12,13] Compared with nonaqueous alkali-ion batteries, the use of cheap and high ambient stable zinc metal anode and inexpensive aqueous electrolyte with superior ionic conductivity (Figure 1a) would make such type of battery to be one of the most promising commercial candidates in the future market. [14-17] To date, extensive studies have been reported for AZIBs, and relating publications have dramatically increased especially in these two years, as shown in Figure 1b. However, the insufficient energy density seems to become the bottleneck that hinder their practical applications at current status. [4,5,18] Such issue could be ascribed to the narrow operating voltage of aqueous electrolyte, insufficient electrochemical performance of cathode materials, and Zn anode. [13,19,20] Besides, the influence of other components such as separator and collector also should be considered to some extent. [20,21] Among them, the studies of widening operating voltage of electrolyte and the optimization of other components only received less attention, which still remain at the early stage. [22,23] On the contrary, more attentions were paid to the electrochemical performance tuning of electrode materials. [24-26] Besides, considering the fixed operating voltage of Zn metal anode, the modification of cathode materials seems to provide more possibilities to effectively improve the energy density of AZIBs, owing to their rich material systems. [20,26,27] Under these considerations, the rational design of advanced cathodes is expected to be a preferential task to develop. Up to now, many types of materials have been exploited as cathode candidates and applied for AZIBs, however, those Rechargeable aqueous zinc-ion batteries (AZIBs) have attracted extensive attention and are considered to be promising energy storage devices, owing to their low cost, eco-friendliness, and high security. However, insufficient energy density has become the bottleneck for practical applications, which is greatly influenced by their cathodes and makes the exploration of high-performance cathodes still a great challenge. This review underscores the recent advances in the rational design of advanced cathodes for AZIBs. The review starts with a brief summary and evaluation of cathode material systems, as well as the introduction of proposed storage mechani...

“…At the early stage of developing rechargeable ZIBs, as a representative energy storage material, MnO 2 has received extensive attention due to its large natural abundance, structural tunability and high Zn storage properties [147]. Layered or tunnel structure of MnO 2 can reversibly intercalate/de-intercalate Zn ions [148].…”

Zinc‐ion storage is a promising electrochemical energy field due to loads of its advantages like easy preparation, environmental friendliness, high safety performance, and high capacity. Carbon materials have been widely studied for zinc‐ion storage due to their extraordinary properties such as earth‐abundancy, low‐cost, good electrical conductivity, various structures, and good stability. This article reviews some widely used carbon materials in zinc ion storage devices, including hollow carbon spheres, activated carbon, N‐doped porous carbon, graphene, and carbon nanotubes. The unique roles and advantages of these carbon materials in both zinc ion supercapacitors and zinc ion batteries are emphasized. Characteristics and functionalizations of different carbon materials are also comparatively discussed in view of zinc‐ion energy storage devices. Finally, some challenges and perspectives of carbon materials in zinc‐ion energy storage are outlined.
