“…Cyclic voltammetry (CV) was carried out to evaluate the electrochemical behavior of GO, rGO‐200, and rGO‐500 at 10 mV s −1 within a stable voltage window of 0.01–1.8 V. [ 28,36–40 ] As shown in Figure a, in comparison with GO and rGO‐500, rGO‐200 displays the most prominent redox peaks near 0.9/1.2 V at 10 mV s −1 attributable to the conversion between CO and COH. [ 29,41–43 ] Correspondingly, rGO‐200 also shows the longest charge/discharge time in the GCD profiles at 0.5 A g −1 (Figure 2b), manifesting the highest specific capacitance. Electrochemical impedance spectroscopy (EIS) was tested at open‐circuit potential (Figure 2c).…”

Recently, developing matchable cathode materials of Zn ion hybrid capacitor still remains difficult owing to insufficient understanding of the charge storage behavior. However, most previous efforts are devoted to explain the effect of oxygen-containing groups without paying attention to graphitic structure. Herein, the charge storage capability and electrochemical kinetics of reduce graphene oxide (rGO) nanosheets are optimized as a function of their surface properties. Beyond the contribution of oxygen-containing groups, an extra contribution from the reversible adsorption/desorption of H + on carbon atom of rGO sheets is confirmed. Electrochemical analysis and density functional theory calculations reveal that H + induces disruption of π cloud in aromatic domain, accompanied by C sp 2 -sp 3 re-hybridization and the distortion/restoration of graphitic structure. The optimal electrochemical performance with a specific capacitance of 245 F g -1 at 0.5 A g -1 with 53% retention at 20 A g -1 is achieved for rGO thermally treated at 200 °C. As a proof-of-concept application, the 3D printed rGO electrode delivers a high areal capacitance of 1011 mF cm -2 and an energy density of 266 μWh cm -2 . The study is believed to broaden the horizons of proton adsorption chemistry and shed light on the design of novel electrode materials.

“…[9][10][11][12] The current cathode materials for AZIBs mainly include manganese-based materials, [13][14][15][16] vanadium-based materials, [17][18][19][20][21] Prussian blue and its analogs, [22][23] and organic compounds. [24][25][26] Among them, MnO 2 characterized by high theoretical capacity (308 mAh g −1 , contributed capacity of single electron transfer), cost-effectiveness, high natural abundance, and environmental friendliness has attracted extensive scientific attention. [27] Moreover, because of the favorable 2 × 2 tunnels with size of 4.6 Å, 𝛼-MnO 2 is considered as a compelling cathode material for AZIBs.…”

The development of MnO 2 as a cathode for aqueous zinc-ion batteries (AZIBs) is severely limited by the low intrinsic electrical conductivity and unstable crystal structure. Herein, a multifunctional modification strategy is proposed to construct N-doped KMn 8 O 16 with abundant oxygen vacancy and large specific surface area (named as N-KMO) through a facile one-step hydrothermal approach. The synergetic effects of N-doping, oxygen vacancy, and porous structure in N-KMO can effectively suppress the dissolution of manganese ions, and promote ion diffusion and electron conduction. As a result, the N-KMO cathode exhibits dramatically improved stability and reaction kinetics, superior to the pristine MnO 2 and MnO 2 with only oxygen vacancy. Remarkably, the N-KMO cathode delivers a high reversible capacity of 262 mAh g −1 after 2500 cycles at 1 A g −1 with a capacity retention of 91%. Simultaneously, the highest specific capacity can reach 298 mAh g −1 at 0.1 A g −1 . Theoretical calculations reveal that the oxygen vacancy and N-doping can improve the electrical conductivity of MnO 2 and thus account for the outstanding rate performance. Moreover, ex situ characterizations indicate that the energy storage mechanism of the N-KMO cathode is mainly a H + and Zn 2+ co-insertion/extraction process.

Aqueous zinc-ion batteries (ZIBs) have emerged as a cost-effective and safe energy storage technology but have remained a challenge in developing efficient Zn 2+ hosting materials for large-scale applications. The authors have herein designed a ladder-type dithieno[3,2-b:2′,3′-d]pyrrole core twisting hydroquinone or pyrocatechol redox pendants as redox conducting polymer cathodes for highly-efficient and robust aqueous ZIBs. The impact of pendant configuration on the energy level, Zn 2+ hosting behavior, and battery performance of these polymer electrodes are systematically investigated. Experimental and theoretical studies clearly reveal the outstanding molecular planarity and highly reversible redox reaction for hydroquinone-derived PDpBQ cathode, which can effectively tackle the bottleneck problems for ZIBs on aspects of structural stability and Zn 2+ insertion/extraction dynamics. Steady capacity output upon 120 mAh g −1 is achieved with considerable rate performance (52.5% of capacity retention at 5 A g −1 ), while pyrocatechol-derived polymer PDoBQ exhibits a sharply fading redox responsiveness (over 45%) due to restricted charge transfer and unselective zinc-ion capturing nature. This molecular design of highly conductive backbone twisting redox pendants with planar molecular plane and specific Zn 2+ hosting as polymer cathodes demonstrates an effective strategy for high-performance and robust ZIBs.
