“…4h). A similar mechanism that turns the disadvantage of consuming H + into the advantage of forming a stable SEI layer was also reported in previous work, 53,58–62 which further confirms the credibility of our explanation. To experimentally confirm the critical effect of this unique SEI layer, we calculated the activation energy for the de-solvation process of Zn(H 2 O) 6 2+ through the law of Arrhenius equation (Fig.…”

“…More importantly, unlike the solid-liquid interface reactions, solid-solid interface reactions often possess complex and slow reaction kinetics, which hinders the further development of SSEs in energy storage/conversion systems. [21][22][23][24] A lot of work has been done to enhance the electrochemical performance of SSE-based energy storage and conversion systems and have achieved some progress. For instance, the enhanced SSE-based batteries can exhibit high-ionic conductivity of 2 × 10 −3 S cm −1 as well as long cycling life of more than 3000 cycles for LIBs, [25] excellent discharge capacity of 9340 mA h g −1 in lithium-oxygen battery, [26] quick synthesis method of 5 min, [27] and so on.…”

Nowadays solid‐state batteries have become a hot spot in the research of batteries and a significant candidate for commercial batteries for the increasing demands for good safety and excellent energy density. Metal‐organic frameworks (MOFs) have been considered as suitable materials for solid‐state electrolytes (SSEs) for the merits of regular channels and large specific surface areas, which can provide a promising structural platform for fast‐ion conduction. Therefore, numerous kinds of MOF‐based SSEs with enhanced electrochemical performance have been successfully synthesized and studied in recent years. In this review, the recent progress (synthesis methods, physical and chemical characteristics) of MOF‐based SSEs for secondary batteries have been summarized. Finally, the challenges and opportunities faced by the future development in this field are put forward, hoping to provide some enlightenment for the synthesis of MOF‐based SSEs, so as to create more efficient, long‐lasting, and safe SSE‐based secondary batteries.

“…More importantly, water, as the aqueous electrolyte, has excellent ionic conductivity, high specific heat capacity, and inherent nonflammability, which can deliver unparalleled safety and allow cycling at large current densities. Therefore, AZIBs promise to be the next-generation alternative for energy storage. − So far, the main cathodes of AZIBs are based on inorganic materials, such as manganese (Mn)/vanadium (V)-based compounds, Prussian blue analogues, and polyanionic olivine-based phosphates. − The high price and large ionic radius of Zn 2+ may lead to slow ionic dynamics and structural collapse in inorganic materials during extraction/insertion . Besides, the reported inorganic materials are also facing difficult challenges such as limited resources, unsuitable electrode potentials, and strong polarization, which may result in low capacity and inferior cycling stability. − …”

Organic electrodes have been identified as promising energy-storage materials for aqueous zinc-ion batteries (AZIBs). Small molecular materials have ideal redox properties, high specific capacity, and structural diversity, making them a category of cathode candidates for AZIBs. However, the instability and dissolution during the extraction and insertion of H+/Zn2+ limit their application of the long-cycle stability for AZIBs. Herein, a small-molecule nanosheet (NI-DAQ, ∼14 nm in thickness) with imide linkage is designed and synthesized by the condensation of anthraquinones and anhydrides. It not only inhibits the dissolution of monomer electrodes but also boosts the reactivity and conductivity of the whole molecule by the introduction of π-conjugated imide groups and extended aromatic planes. Therefore, the NI-DAQ electrode obtains a large initial capacity of 191.9 mA h g–1 at 50 mA g–1 and superior cyclability after 3000 cycles at 500 mA g–1 with a minor average capacity fading rate of 0.01% per cycle. Moreover, in situ Fourier transform infrared (FT-IR) and ex situ X-ray photoelectron spectroscopy (XPS) characterization techniques have been implemented to investigate the redox mechanism of CO units in AZIBs for the NI-DAQ electrode. Thus, a promising conductive molecule is developed and explored in this paper, which can provide insights into the application of organic materials in AZIBs.
