“…However, organic electrolytes are usually used in these hybrid ion capacitors, which leads to limited ionic conductivity and serious safety issues. [486,487] Meanwhile, it has been found that the hybrid capacitors based on multivalent ions (Zn 2+ , Ca 2+ , Mg 2+ , and Al 3+ ) in aqueous solution have some unique advantages compared to monovalent ion-based devices, such as more reacted ions can be offered and fast charge transfer kinetics. [488][489][490][491] Among them, ZIHCs are regarded as promisingly emerging aqueous energy storage devices due to the features of abundant zinc resources, high safety, nontoxicity, and easy processing.…”

utilization of environmentally friendly renewable energy sources, such as solar energy, wind energy, and tidal energy. However, these renewable energy sources are intermittent in nature, which makes them unable to provide a stable energy supply. Therefore, energy storage devices play an integral role in setting up renewable energy systems. [1] At present, electrochemical energy storage (EES) technologies are the most commonly used due to high energy conversion efficiency, wide range of energy and power densities, relatively long lifetime, and low maintenance costs, among which lithium-ion batteries (LIBs) and supercapacitors (SCs) are considered to be the promising two. [2,3] LIBs, which have occupied half of the market of EES devices since their successful commercialization more than 30 years ago, have the advantages of high energy density, stable performance, and moderate cost, but their low power density and poor cycle performance are detrimental to fast and longterm energy storage. [4][5][6] By contrast, SCs, another excellent energy storage device, have the ability to store and release energy quickly and has an extremely long cycle life and good safety. The very limited energy density however greatly increases the number of equipment required to store the same energy, thus making SCs undesirable to meet the actual demand for high energy storage. [7][8][9] Consequently, in order to assist in realizing the vision of replacing nonrenewable fossil energy with environmentally friendly renewable energy, EES devices that can concurrently provide good energy density and high power performance are urgently needed.As a new type of EES device emerging after metal-ion batteries (MIBs) and SCs, metal-ion hybrid capacitors (MHCs) blessed with fabulous power performance, decent energy density, and remarkable cycle stability are considered to be one of the most prospective EES devices. [10] In 2001, the first MHC, using activated carbon (AC) as the cathode and nanostructured Li 4 Ti 5 O 12 (LTO) as the anode, was constructed by Amatucci et al., which possessed an energy density as high as 20 Wh kg −1 , about threefold than that of traditional SCs, showing promising rate capability in the meanwhile. [11] ThisThe design and development of advanced energy storage devices with good energy/power densities and remarkable cycle life has long been a research hotspot. Metal-ion hybrid capacitors (MHCs) are considered as emerging and highly prospective candidates deriving from the integrated merits of metal-ion batteries with high energy density and supercapacitors with excellent power output and cycling stability. The realization of high-performance MHCs needs to conquer the inevitable imbalance in reaction kinetics between anode and cathode with different energy storage mechanisms. Featured by large specific surface area, short ion diffusion distance, ameliorated in-plane charge transport kinetics, and tunable surface and/or interlayer structures, 2D nanomaterials provide a promising platform for manufacturing battery-type electrod...

“…With the 3.0 M H 2 SO 4 electrolyte being used in a supercapacitor, the composite film provided a large specific capacitance of 326.7 F g −1 at a current density of 1 mA cm −2 and remained stable at a large current density of 10 mA cm −2 with a specific capacitance of 217.5 F g −1 and an excellent cycling stability (89.6% retention after 10 000 cycles). He et al 22 synthesized Zn-doped δ -MnO 2 nanoflowers by a simple hydrothermal method. The layered structure provided by δ -MnO 2 is beneficial to store a large amount of Zn 2+ and provide abundant ion transport paths during the electrochemical process, accelerating ion intercalation/extraction during the reaction.…”
