“…Due to relatively large surface tension (water: 72.8 mN m -1 , NMP: 40.8 mN m -1 at 20 °C), water-based slurries are difficult to coat on the current collector such as aluminum or copper foil. [135][136][137] It is therefore much easier for the electrode to be detached causing decay in the capacity. Apart from this, electrode materials Energy density of 93.9 Wh kg −1 in structural battery at 0.2C [40] particularly cathodes in SIBs and LIBs suffer from several other challenges such as high-temperature and/or high-voltage capacity fading, triggered by unfavorable side reactions.…”

Inorganic materials form an emerging class of water‐soluble binders for battery applications. Their favourable physicochemical properties, such as intrinsic ionic conductivity, high thermal stability (>1000 °C), and compatibility to coat a diverse range of electrode materials make them useful binders for lithium‐ion and sodium‐ion batteries. Li and Na containing phosphates and silicates are attractive choices as multifunctional inorganic aqueous binders (IABs). This review discusses these binders' structural, thermal, and ionic properties, followed by exploiting their ionically conducting nature for all‐solid‐state batteries. Subsequently, the application of these compounds as binders and surface coating agents for different anodes and cathodes in lithium‐ion and sodium‐ion batteries is discussed. Eventually, a first evaluation of their environmental impacts and economic aspects is presented as well.

“…[1][2][3][4][5] As a key type of energy storage system, electrochemical batteries play an essential role in the huge field of energy storage and conversion. Among the existing and extensively developed battery systems, [6][7][8] lithium-ion batteries (LIBs) have attained overwhelming success in commercialization and large-scale production over the past more than two decades, owing to their high open-circuit voltage, generally good reliability in cycling, and relatively high energy density. 9,10 However, the application of LIBs in large-scale energy storage is handicapped by several apparent drawbacks, for example, the poor safety and long-term nonsustainability of the key metals for both anode and cathode.…”

Better engineering layered vanadium oxides for aqueous zinc‐ion batteries: Going beyond widening the interlayer spacing

et al. 2023

Aqueous zinc‐ion batteries (ZIBs) are regarded as among the most promising candidates for large‐scale grid energy storage, owing to their high safety, low costs, and environmental friendliness. Over the past decade, vanadium oxides, which are exemplified by V2O5, have been widely developed as a class of cathode materials for ZIBs, where the relatively high theoretical capacity and structural stability are among the main considerations. However, there are considerable challenges in the construction of vanadium‐based ZIBs with high capacity, long lifespan, and excellent rate performance. Simple widenings of the interlayer spacing in the layered vanadium oxides by pre‐intercalations appear to have reached their limitations in improving the energy density and other key performance parameters of ZIBs, although various metal ions (Na+, Ca2+, and Al3+) and even organic cations/groups have been explored. Herein, we discuss the advances made more recently, and also the challenges faced by the high‐performance vanadium oxides (V2O5‐based) cathodes, where there are several strategies to improve their electrochemical performance ranging from the new structural designs down to sub‐nano‐scopic/molecular/atomic levels, including cation pre‐intercalation, structural water optimization, and defect engineering, to macroscopic structural modifications. The key principles for an optimal structural design of the V2O5‐based cathode materials for high energy density and fast‐charging aqueous ZIBs are examined, aiming at paving the way for developing energy storage designed for those large scales, high safety, and low‐cost systems.

“…The LSBs have a high theoretical capacity and the advantages of being inexpensive, environmentally friendly, and safe. 15,16 However, sulfur has no intrinsic electron conductivity, and the shuttle effect of highly soluble polysulfide intermediates [17][18][19] leads to irreversible capacity. Severe volume expansion also occurs during the conversion from S to Li 2 S. 17,20,21 The design of an electrolyte or a separator, as well as heteroatom doping or porous carbon supports are being researched as a potential solution to these issues.…”

With the rapid growth of secondary batteries used in various industries, methods for analyzing battery elements such as electrodes and electrolytes have also improved. In addition, as the utility of nano‐scaled electrode materials have attracted greater attention, it has become increasingly clear that conventional electrochemical analytic methods have limitations. Consequently, electron microscopy and even synchrotron x‐ray radiation techniques have been adopted and are now widely used. Among several advanced analytical techniques, synchrotron radiation‐based operando small‐angle x‐ray scattering (SAXS) enables real‐time analysis of changes in the ordering of nanostructures and in the electron densities of electrodes and solid electrolytes during electrochemical reactions. In this review, the principle and applications of operando SAXS are briefly introduced, to help in understanding the complex nanostructural behaviors of battery components used in secondary batteries, and furthermore, it is hoped to contribute to innovative materials design.
