“…It seems that more researchers have not paid enough attention to the development of organic molecular pre‐intercalation, which leads to the lack of emphasis on controllable preparation methods and improved performance mechanisms. Tunable organic pre‐intercalation could provide a strategy to expand the lattice d‐spacing of the host materials for ion storage, so as to achieve rapid ion diffusion kinetics (Figure 5a) [62,63] . Furthermore, the widen space is also conducive to the intercalation and storage of more guest ions, thus extending the redox pairs involved in the reaction.…”

Advantages concerns about abundant resources, low cost and high safety have promoted sodium‐ion batteries (SIBs) and aqueous zinc‐ion batteries (AZIBs) as the most promising candidates for next generation of low‐cost large‐scale energy storage. However, the state‐of‐the‐art cathode materials are far from meeting the commercial requirements. Considering the unique open framework, layered vanadium oxides have attracted wide attention due to the high energy density and power density, while they also face critical issues such as low stability and sluggish diffusion kinetics. The interlayer doping defects, as the most common method modulating layered materials, are believed to solve these problems which will be highlighted in this review. Firstly, the characteristics and current states of various vanadium oxides in SIBs and AZIBs are summarized. Then, the research efforts related to different types of interlayer doping defects, including ionic, molecular doping, etc., are discussed. Finally, it is pointed out that it is not enough to merely achieve satisfactory performances. Hence, some perspectives about the deep understanding and interrelationship are provided for the subsequent rational design of defective layered vanadium oxides for low‐cost energy storage systems.

“…The electrochemical results showed that the rose-like polyaniline-intercalated vanadium oxide architectures displayed unprecedented zinc-ion storage performances. [121] As a matter of fact, poly (3,4-ethylenedioxythiophene (PEDOT) has been also verified to display greatly enhanced stability in comparison to polypyrrole and polyaniline, which has drawn great attention in the electrochemical energy storage over these years. Based on this background, Xia et al put forward ammonium vanadate oxide (NVO) embedded by PEDOT through a redox intercalative polymerization (PEDOT-NVO).…”

In consideration of low cost, simple operation, safe reliability, and environmental benignity, aqueous rechargeable batteries (ARBs) have attracted great interest among portable electronic devices, energy storage, and power source batteries. As the key components of ARBs, the electrode materials lead to a crucial effect for the overall battery properties, such as working voltage, electrocatalytic activity, capacity, and cycling stability. However, owing to the highly reactive aqueous environment, the electrode materials typically demonstrate a series of issues, including active material dissolution, structural instability, and poor catalytic activity, restricting their application. So far, several researchers have devoted much effort to improve the properties of electrode materials for ARBs. In particular, intrinsic structure modification in terms of vacancy regulation, interlayer engineering, and element doping have been applied to optimize the electronic and phase structure of electrode materials, contributing to elevated ion diffusion, fast charge transfer, and adequate active sites for electrochemical reaction. In this review, recent reports are demonstrated about the intrinsic structure modification of electrode materials in aqueous metal‐ion and metal‐air batteries, focusing on various regulation strategies and functional mechanisms. Finally, a brief conclusion and perspective is presented to demonstrate constructive suggestions and opinions for further research.

“…Very recently, a conjugated polymer and water cointercalation strategy was investigated for the first time to boost the performance of V 2 O 5 . [ 89 ] In this work, rose‐like polyaniline intercalated vanadium oxide (PVO) architecture was successfully synthesized through a facile in situ oxidative/intercalative polymerization of aniline into V oxide (Figure 5b). The interlayer spacing of the cathode obviously increased from 5.77 to 14.02 Å due to polyaniline and water cointercalation.…”

Rechargeable aqueous zinc‐ion batteries (ZIBs) are regarded as a promising candidate for next‐generation green energy storage systems owing to their high safety, low‐cost, and low toxicity. Metal oxides with layered or tunnel structure are commonly applied as cathodes for ZIBs, but the electrochemical performance is severely limited by the structure collapse and sluggish diffusion kinetics. Preintercalating guest species into host structure is an effective strategy to solve these problems. Herein, a comprehensive overview on the recent developments of intercalation strategy in ZIBs is presented. The category and effect of guest species used in different cathode materials are presented. The issues and future research prospects in intercalation strategy are also discussed in this review.
