“…[43][44][45] The reversible transformation of these NH bands into anionic N − with deprotonation was demonstrated using fluorescence and solid-state UV-vis spectra (Figure S18, Supporting Information). [44] It was further demonstrated that the anionic DAAQ-TFP-COF remained chemical stable during the deprotonation transformation of NH bands via 13 C NMR, PXRD, thermogravimetric analysis (TGA), and N 2 adsorption-desorption measurements (Figure S19, Supporting Information). It is worth noting that, in the case of higher-pH electrolytes, with the deepening of deprotonation degree, the electron migration rate in conjugative configuration II could be accelerated, which improves the conductivity of the DAAQ-TFP-COF.…”

Furthermore, in order to meet the future application requirements of electronic devices and hybrid electric vehicles, it is urgent to develop advanced energy storage devices combining high energy density and power density, as well as long cycle life. [3,4] Lithium (Li)-ion capacitors (LICs), also known as lithiumion hybrid capacitors, as a potential hybrid energy storage device, combining Faradaic feature and capacitive behavior, bridge the performance gap between lithiumion batteries (LIBs) and supercapacitors (SCs), and are expected to solve the above issues. [5] As a typical configuration, LICs can generally be constructed with a non-Faradic capacitor-type electrode (enable fast charging/discharging rates) and a Faradic battery-type electrode (enable great specific capacity and energy density) in Li-salt-containing organic/aqueous electrolytes, and the comprehensive energy performance can be achieved for LICs. [6] Generally, the focus of this research field is mainly on those LIC devices that use nonaqueous electrolytes restricted by the trouble of highly flammability, toxicity, and volatility. [7] Aqueous LICs (ALICs) using aqueous Li-salt solutions (LiCl, LiNO 3 , and Li 2 SO 4 , etc.) as electrolytes are promising candidates thanks to the high security and processability, low cost, high ionic conductivity, along with simple assembly process. [1,8] Previous researches have made some refreshing progress in ALICs mainly assembled with lithium-intercalation compounds as cathode electrode and activated carbon (AC) as anode electrode. [9,10] Unfortunately, the cycling and rate capability of these cathode materials were reported to be very poor caused by violent volume expansion and slow reaction kinetics, resulting in the inferior performances of the ALICs, [11] which make ALICs fail to attract strong interest from researchers. Thus, the urgent demands for enhanced electrochemical performance of ALICs lie in the development of innovative configuration of anode and cathode (MoS 2 @α-Fe 2 O 3 /carbon nanotube fiber (CNTF)//LiCoO 2 / CNTF, [12] boron-doped graphene (BDG)/boron-doped diamond (BDD)/TiO 2 //BDG/BDD, [13] Ti 3 C 2 T x MXene//porous carbon (PC)) [14] as well as design and synthesize high-performance electrode materials. Aqueous lithium storage devices are promising candidates for next-generation energy storage applications, featuring low-cost, safety, environmental benignness, and grid-scale merits. Developing reliable anode materials with fast Li + diffusion is paramount to stimulate their development. Herein, the electrochemical performance and mechanism of a redox-active β-ketoenamine-linked covalent organic framework (COF) (2,6-diaminoanthraquinone and 2,4,6-triformylphloroglucinol COF, DAAQ-TFP-COF) for lithium storage in aqueous electrolyte are explored for the first time. Systematic studies demonstrate that, by the conversion of neutral COF into anionic COF via a pinpoint surgery on the β-ketoenamine linkage, the resultative COF shows doubled Li + storage capacity (132 mAh g −1 at 0.5 A g −1 , 87%...

and portable electronics, among others) and attenuate high-frequency noise during switching or voltage decline. [1] The most commonly used filtering device, the aluminum electrolytic capacitor (AEC), is imitated by its bulky nature and low capacitance, which make it unsuitable for use in modern electronic circuits. [2][3][4] Electrochemical capacitors have unique characteristics such as long lifetime, high power density, rapid charge-discharge, reduced maintenance requirements, frequency adaptability, and moderate energy density. [5,6] These outstanding characteristics suggest that electrochemical capacitors are ideal candidates to replace AEC that will allow the advancement of modern electronics. [7] In order for electrochemical capacitors to become established as AC line filters, specific key parameters must be obtained: low internal resistance, negligible contact resistance between electrode and current collector, large nanopore size electrode, and better ionic/electronic conductivity of the electrode. [8,9] In 2010, John R. Miller made a breakthrough by fabricating an electrochemical capacitor using a nanostructured carbon electrode for high-frequency adaptability to replace AEC. [10] This seminal discovery led to many reports of carbon-based materials, such as vertically aligned graphene, SWCNT, carbon black, PEDOT, and PEDOT composites, that were demonstrated to have high-frequency adaptability for the replacement of AEC. [8,[11][12][13][14][15][16] Recently, M. Wu et al. reported the asymmetric supercapacitor (PEDOT║ErGO) for AC line filtering applications in aqueous electrolyte. [17] Z. Fan et al. prepared carbon samples from various precursors (ZIF 67, Prussian blue, and cellulose), and demonstrated their high-frequency response in AC line filtering applications. [18][19][20] C. Zhang et al. reported a hybrid carbon nano-onion/graphene symmetric supercapacitor (SSC) which could be used as a compact AC filter. [9] Very recently, Y. Gogotsi and coworkers explored the AC line filtering properties of 2D MXene by varying the electrode thickness. [8,21] Most high-frequency capacitors use aqueous electrolytes with high ionic conductivity with restrictive operating voltages (maximum 1 V), which hinders their real-world application. Few reports in the literature employ CNTs and carbonbased materials in combination with an organic electrolyte to explore their high-frequency response. The methods used for engineering these materials are very complex and costly, preventing commercialization. [4,22,23] Overcoming these barriers The filtering device is a vital component of electronic goods that rectifies ripples which occur upon converting alternating current (AC) to direct current (DC) and attenuates high-frequency noise during switching or voltage declines. Classical filtering devices suffer from low performance metrics and are bulky, limiting their use in modern electronic devices. The fabrication process of electrode materials for high-frequency symmetric supercapacitor (HFSSC) is complicated, hindering commercial...

“…In order to promote the energy density of aqueous SCs, constructing asymmetric hybrid SCs using the battery-type electrode and electric-double-layer capacitive electrode (such as porous AC) is regarded as an effective strategy, − where the battery-type electrode and electric-double-layer capacitive electrode are used as the energy and power sources, respectively. − Besides, compared with other types of hybrid SCs with a low energy density, such asymmetric hybrid SCs using the battery-type electrode and electric-double-layer capacitive electrode can provide a higher energy density and a relatively satisfactory power density. Therefore, the behavior of this kind of hybrid SCs resembles that of an SC with a high energy density, such as lithium-ion, − sodium-ion, − and potassium-ion hybrid SCs. − Very recently, a new kind of aqueous magnesium-ion hybrid SCs (MHSs) has attracted increasing attention due to similar radius and electrochemical characteristics of magnesium ions to lithium ions. − Zheng et al prepared an aqueous rechargeable MHS (0–2.0 V) using commercial spinel Mn 3 O 4 as the cathode, coupled with AC as the anode, which exhibited a high energy density of 20.2 W h kg –1 at a power density of 125 W kg –1 . Cao et al reported that a Mg-OMS-2 (manganese oxide octahedral molecular sieves)/graphene//AC aqueous MHS (0–2.0 V) achieved a high energy density of 46.9 W h kg –1 at a power density of about 100 W kg –1 .…”

Recently, as a new type of hybrid supercapacitors, aqueous magnesium-ion hybrid supercapacitors (MHSs) have triggered continuous attention. Benefiting from the insertion/extraction processes of bivalent magnesium ions in the battery-type electrode, MHS offers the advantage of charging two electrons per ion into the battery-type material. However, the low energy density of reported MHSs is still unsatisfying for their practical applications. Herein, a novel redox bromide-ion additive aqueous MHS (B-MHS) has been designed via introducing the Br3 –/Br– redox additive in 1 M MgSO4 electrolyte to promote their energy density. The optimally designed B-MHS exhibits the highest specific capacity of 268.1 mA h g–1 at a current density of 2 A g–1 in a wide voltage range of 2.6 V (0–2.6 V). Also, the maximum energy density of 262.3 W h kg–1 can be achieved at a power density of 1956.8 W kg–1, which is better than that of MHS. Most importantly, the energy storage mechanism and interactive correlation between magnesium ion insertion/extraction and redox reaction (Br3 –/Br–) have been detailedly investigated. The proposed strategy provides a new route in promoting the energy density of MHS, which should be helpful in designing and constructing high-energy-density storage devices.
