“…Although the SAM interface has been demonstrated to efficiently block the interfacial proton transport, ensuring its high stability is of importance for the subsequent application in HER‐free and stable Zn anodes. In previous works, IL cations (such as MIM + , [13] EMIM + , [11d] etc .) adsorbed on the Zn anode surface by electrostatic interaction usually show relatively poor stability because of the low electronegativity of metallic Zn.…”

Aqueous Zn‐ion batteries (ZIBs) are promising next‐generation energy storage devices, yet suffer from the issues of hydrogen evolution reaction (HER) and intricate side reactions on the Zn anode surface. The hydrogen (H)‐bond networks play a critical role in interfacial proton transport that may closely relate to HER but are rarely investigated.Herein, we report a self‐assembled monolayer (SAM) strategy which is constructed by anchoring ionic liquid cations on Ti3C2Tx substrate for HER‐free Zn anode. Molecule dynamics simulations reveal that the rationally designed SAM with a high coordination number of water molecules (25~27, 4~6 for Zn2+) largely reduces the interfacial densities of H2O molecules, therefore breaking the connectivity of H‐bond networks and blocking proton transport on the interface, by which the HER is suppressed. Then, a series of in‐situ characterizations demonstrate that negligible amounts of H2 gas are collected from the Zn@SAM‐MXene anode. Consequently, the symmetric cell enables a long‐cycling life of 3000 h at 1 mA cm−2 and 1000 h at 5 mA cm−2. More significantly, the stable Zn@SAM‐MXene films are successfully used for coin full cells showing high‐capacity retention of over 94% after 1000 cycles and large‐area (10 × 5 cm2) pouch cells with desired performance.

“…HEEs can also enhance the safety performance of rechargeable batteries. − Excessive gas production and low flash points of electrolytes cause massive thermal runaway behaviors of batteries. , The HEEs can increase the boiling point of the electrolytes based on the colligative properties, which improves the high-temperature performance and thermal safety of the battery. You et al believed that a “cocktail” of polyfluorinated solvents and high-boiling-point solvents is the best choice for constructing nonflammable electrolytes (Figure c) …”

“…For example, 3,4,9,10perylenetetracarboxylic dianhydride exhibited excellent cycling lifespan in high concentration electrolytes, with an 87% capacity retention under 1 A•g -1 over 1,000 cycles [113] . In addition, electrolytes can also be optimized from the perspectives of ionic liquids [114][115][116] , electrolyte additives [117][118][119] , organic solvents [120][121][122] , and quasi/all-solid electrolytes [123][124][125] . Additionally, 5,7,12,14-pentacenetetrone cathodes were found to be more stable in 1 M Zn(CF 3 SO 3 ) 2 electrolytes containing trimethyl phosphate (TMP) additives (with a 61.86% capacity retention under 0.1 A•g -1 after 550 cycles) than in 1 M Zn(CF 3 SO 3 ) 2 electrolytes [126] , due to the strong interaction between Zn 2+ and TMP that changes the solvation structure and inhibits parasitic reactions.…”

Aqueous zinc batteries that utilize metallic Zn as the anode are considered as a promising alternative to lithium-ion batteries due to their intrinsic high safety, low cost, and relatively high energy density. Compared to inorganic cathodes, organic cathodes exhibit several advantages including high theoretical capacity, tunable structure, abundant sources, and environmental friendliness. In this paper, we summarize the recent progress in organic cathodes for aqueous zinc-organic batteries, covering the working mechanisms of three typical types of organic cathodes, their electrochemical performance, and common strategies for further improvement. Finally, we discuss the current challenges and possible future research directions. We hope this review will offer useful information for exploring high-performance organic cathodes.
