“…The ZIC can still deliver a gravimetric specific capacitance of 112.2 F g −1 even at a high current density of 60 A g −1 , demonstrating its superior rate capability. Notably, an ultrahigh power density of 48.8 kW kg −1 with a correspondingly high energy density of 40.4 Wh kg −1 can be achieved at a current density of 60 A g −1 , which is the highest value among the ZICs [ 11,13,15,19,20,22,37–43 ] and ZIBs [ 12,44–48 ] reported recently. Considering ZIC with PC800 cathode can deliver twice the energy density and six times the power density of the ZIC with commercial YP‐50F cathode (50.2 Wh kg −1 and 7.4 kW kg −1 ), [ 49 ] we believe our ZIC with PC800 cathode is a promising device for practical energy storage applications.…”

storage systems are preferred due to their high safety and low capital cost. [2] However, commercial aqueous lead-and nickel-based rechargeable batteries possess low energy densities (≈45 Wh kg −1 for Pb-acid batteries; [3] ≈50 Wh kg −1 for Ni-Cd batteries [4]) and limited life spans, which increases the energy storage cost per unit energy output, [5,6] thus limits their practical applications. Zinc metal is considered as an ideal anode for aqueous energy storage devices because of its high theoretical capacity (gravimetric, 820 mAh g −1 ; volumetric, 5851 mAh cm −3), low potential (−0.76 V vs standard hydrogen electrode (SHE)), and high hydrogen evolution overpotential. [7] Zinc-based rechargeable batteries and capacitors are expected to be low-cost, long-life energy storage devices since they utilize inexpensive zinc metal anode and aqueous electrolytes. [8,9] However, most transition-metal oxide cathodes display limited cycle life due to dissolution and parasitic reactions, which deteriorate the cycling performance of zinc ion batteries. [10] Electrochemical zinc ion capacitors (ZICs) are hybrid supercapacitors consisting of zinc anodes and porous carbon cathodes. [11,12] On the one hand, theoretically, a porous carbon cathode has unlimited cycle life due to the adsorption/desorption charge storage mechanism without phase transition. [13] On the other hand, the zinc anode shows Faradaic reactions with infinite theoretical capacitance compared with a porous carbon cathode, which exerts the maximum electric double-layer capacitance (EDLC) of porous carbon cathode. [14] Nevertheless, in an aqueous ZIC system, commercial porous carbon has low capacity, energy density and power density (typical values are ≈55 mAh g −1 , 43.1 Wh kg −1 , and 12.0 kW kg −1 for YP-50F, Kuraray Chemical, Japan) [15] due to its EDLC dominated charge storage mechanism. [16,17] Therefore, novel porous carbon cathodes are designed to boost the electrochemical performances of full-cell ZIC. [18] Kang and coworkers reported a ZIC with activated carbon cathode and Zn anode in an aqueous ZnSO 4 electrolyte. [19] The assembled ZIC delivered a capacity of 272.3 F g −1 and a high power density of 14.9 kW kg −1 with a corresponding energy density of 30 Wh kg −1 in the operational voltage window of 0.2-1.8 V. Liu and coworkers employed a porous carbon cathode to assemble ZIC. The as-fabricated ZIC delivered a capacitance of 298.6 F g −1 , a maximum energy density of 82.36 Wh kg −1 , and a maximum power density of up to 3.76 kW kg −1 in the operating voltage Aqueous electrochemical zinc ion capacitors (ZICs) are promising next-generation energy storage devices because of their high safety, inexpensive raw materials, and long cycle life. Herein, an aqueous ZIC with superior performance is fabricated by employing an oxygen-rich porous carbon cathode. Excellent capacitance and energy density are obtained thanks to the electric double-layer capacitance of porous carbon, and additional pseudocapacitances originating from the variation in oxidation states ...

“…The cathode material is critical for the overall performance of ab attery.S uffering from the two-electron reactiona nd the large ionic radius of the Zn 2 + ion (0.074 nm) during the discharge/charge process, the zinc-storage process must overcome al arge ion-migration energy barriera nd high electrochemicalp olarization.T his leads to structural damage and phase transformation of the host materials, resulting in low reversible capacity and fast capacity fade for ZIBs. [12,13] Up to now,o nly af ew cathode materials have been investigated for Zn 2 + storage, such as manganese-based oxides, [14,15] Prussian blue and its analogues, [16,17] molybdenum disulfide, [18] polyanionic compounds, [19] and vanadium-basedc ompounds. [20][21][22][23] Amongthose materials, the manganese-based oxides, especially MnO 2 ,h ave been considered as the most promisingh ost materials for zinc in aqueous electrolytes, owing to their low cost, low toxicity, abundant resources of manganese in earth, high voltage platform of approximately 1.4 V( vs. Zn 2 + /Zn), and high theoretical capacity (308 mAh g À1 ).…”

Aqueous zinc‐ion batteries (ZIBs) have been considered as prospective alternatives for lithium‐ion batteries, which are able to serve as power sources for next‐generation wearable and flexible devices, owing to the merits of abundant zinc resources and high safety of aqueous electrolyte. However, the lack of suitable cathode materials with flexibility for ZIBs hinders their further application. Herein, a novel cathode material [i.e., MnO2 nanosheet‐assembled hollow polyhedron anchored on carbon cloth (MnO2/CC)] was prepared through a rapid hydrothermal method by using ZIF‐67 as self‐sacrificing template. When tested in an aqueous ZIB, the MnO2/CC delivered a high reversible capacity of 263.9 mAh g−1 at 1.0 A g−1 after 300 cycles, far exceeding those of the commercial MnO2 electrode. More importantly, benefiting from the unique structural advantages, a flexible ZIB assembled based on the MnO2/CC displayed a stable output voltage of 1.53 V and a specific capacity of 91.7 mAh g−1 at 0.1 A g−1 after 30 cycles. It also successfully lit LED bulbs even under different bending angles, showing good flexibility. This research contributes to the development of MnO2‐based cathode materials for high‐performance flexible ZIBs.

[77][78][79][80][81] ZnHCF compounds showed a high average redox potential of %1.7 V versus Zn, which is much higher than the reported transition metal oxide/sulfide cathodes (Figure 9a,b). [78] However, the relatively low capacity of %50 mAh g À1 and short cycle life due to transition metal dissolution may limit their applications.…”

Rechargeable mild aqueous zinc batteries have recently attracted tremendous interest for large‐scale grid storage due to their potentially highest energy density and safety, and lowest cost among available aqueous battery technologies. Herein, a variety of cathode materials, zinc anode structures, and electrolytes are briefly reviewed. A multi‐type of charge carriers such as Zn2+, H+, and anions can be reversibly stored in cathodes in rechargeable mild aqueous zinc batteries. The charge storage behavior in cathodes and strategies to address the reversibility and dendrite growth of zinc anodes are comprehensively summarized. Solutions to the remaining challenges such as long‐term stability and economy of cathodes and zinc anodes are discussed. This review also includes an analysis of mild aqueous zinc battery chemistry with reported cathode materials and anode materials. A perspective for the practical development of rechargeable mild aqueous zinc batteries regarding cathode design, zinc anode utilization, and cell configuration is also included to accelerate the commercialization of zinc batteries. In the future, rechargeable mild aqueous zinc batteries would be a visible energy storage solution for grid storage.
