Article Abstract
Aqueous zinc-ion batteries have attracted widespread attention due to their low cost and high safety. Unfortunately, their commercial applications are greatly inhibited by the negative effects of zinc dendrites and side reactions. A solution that utilizes a 3D host can help mitigate these issues. In this paper, we present a 3D host that is composed of an aerogel scaffold with a poly(vinyl alcohol) and MXene structure. The embedded Zn can be densely packed inside the host due to its zincophilic properties. During cycling, the fluorine-based functional groups on the surface of MXene were able to react with the electrolyte to form the ZnF solid electrolyte interphase, which can effectively protect the composite anode. As a result, the symmetrical battery was capable of stable cycling for >300 h at a high current density of 10 mA cm. More impressively, the assembled full cell retained 93.86% after 800 cycles at a current density of 5 A g. This work provides an effective idea for improving the cycling performance of aqueous zinc-ion batteries.

Pre-intercalation has emerged as a highly effective strategy to enhance structural integrity and ion transport kinetics in cathodes for aqueous Zn-ion batteries. Here, we report a zinc-ion pre-intercalated hydrate vanadium oxide cathode, in which the initial insertion of Zn induces a significant expansion of the interplanar spacing, followed by contraction at higher Zn concentrations owing to strong electrostatic interactions with the VO framework. Such competing expansion and contraction of interplanar spacing enhances the overall electrochemical properties.

The Jahn-Teller distortion caused by high-spin state Mn (t e ) is a major limiting factor for improving both the specific capacity and cycling stability of MnO cathodes in aqueous zinc-ion batteries. Thus, an intrinsic strategy for optimizing MnO involves the effective elimination of the high-spin state Mn (t e ) during electrochemical process. Herein, we focus on structural design that constructed NHVO-coated MnO (Mn@V) nanorods to achieve the low-spin state of Mn (t e ) and inhibit the Jahn-Teller distortion.

The mechanical degradation of cathodes during charge-discharge cycling poses a critical limitation to the cycle life of aqueous zinc-ion batteries (AZIBs). Although the degradation of MnO cathodes has been extensively investigated, the underlying reaction mechanisms have long remained a subject of debate, and the associated mechanical evolution during cycling is still poorly understood. In this work, a comprehensive investigation of electrochemical phase transitions and chemical strain evolution in δ-MnO cathode is presented using a custom-built in situ strain testing system based on digital image correlation.

NHVO (NVO) is considered a promising cathode material for aqueous zinc-ion batteries due to its high theoretical capacity. However, its practical application is limited by irreversible deamination, structural collapse, and sluggish reaction kinetics during cycling. Herein, K and CN co-intercalated NVO (KNVO-CN) nanosheets with expanded interlayer spacing are synthesized for the first time to achieve high-rate, stable, and wide-temperature cathodes.
