“…The first aqueous KIHCs based on TMDCs were proposed by Qin et al They synthesized a novel MoPO/MoS 2 nanoplates on carbon cloth (CC) substrate via the facile hydrothermal and electrodeposition methods (Figure 30a). [482] Molybdenophosphate (MoPO) is a promising candidate to insert/extract K + because of its stable chemical properties and excellent electrical conductivity. Accordingly, compared to pristine MoS 2 nanoflakes electrode, the MoPO/MoS 2 composite had the advantages of high K + storage capacitance, low equivalent series resistance, and strong K + diffusion ability.…”

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...

“…The small diameter of the semicircle in the high-frequency region before and after cycling indicates low electron-transport restrictions, low electron-transport resistance, and low solution resistance. 59,60 Also, the slope of the straight line in the low-frequency region is large, which also indicates small diffusion resistance. Meanwhile, the resistance ( R s ) values of {Ag 5 BW 12 O 40 }@Ag-BTC-2-NF are 3.74 Ω and 3.89 Ω before and after cycling, respectively, which are in line with Fig.…”

Summary Potassium‐ion hybrid capacitors (PIHCs) have received extensive attention due to the high‐rate energy density and long‐life cycling capability. However, PIHCs still suffer from structural instability and low power density. Outstanding dimensional engineering can solve the above problems to improve the performance of PIHC anode materials. Here, we systematically summarize the new strategies of preparing dimensionally‐oriented materials for high performance PIHCs anode. To realize the influence of dimensions on high performance PIHC anode materials, we summarize the mechanisms in PIHC anode from one‐dimension, two‐dimension, and three‐dimension, and analyze the problems encountered in improving the performance of PIHC anode materials of different dimensions. Then we make appropriate recommendations on the issues raised, and present future opportunities and challenges for PIHCs. This work can open up new perspectives for developing high performance PIHCs.
