“…adsorbed on or desorbed from the cathode surface when the operating voltage was higher than the zero charge potential, while the electrostatic adsorption/desorption of cations (Zn 2+ ) dominated when the operating voltage was lower. [ 119–121 ] In addition, due to the doping of heteroatoms (usually O, N) on the surface of commonly used carbon‐based cathodes, Zn 2+ /H + can undergo chemical adsorption/desorption on their surfaces, which provided additional pseudocapacitance for the overall capacity. [ 122–124 ] Note that only the adsorption of anions existed in the first charging process.…”

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...

“…Zhang et al 19 further investigated the electrochemical behaviour and stability of AC in electrolytes containing different lithium salts. Techniques such as surface treatment, [20][21][22][23][24][25] defect reduction 15 and atomic layer deposition of ZnO 26 have been utilised to improve the electrochemical stability of AC electrodes, while these modication processes are oen intensive and complex. However, to the best of our knowledge, little attention has been paid to optimise the solvent of the electrolytes used in LiC containing AC electrodes to improve their stability.…”
