“…Hardy et al prepared WO 3 thin films from ac olloidal suspension by using ultrasonic spray deposition on titanium nitride (TiN) and Pt substrates. [161] The WO 3 thin film prepared on the TiNs ubstrate showedagood performance compared with that on the Pt substrate because TiNa llowed ah igherc oulombic efficiency and more stable capacity evolution during the electrochemical process. The WO 3 /TiN thin film prepared at 500 8Ce xhibited a coulombic efficiency of 99.2 %a nd ac apacity of 90 mAh g À1 (640 mAh cm À3 ).…”

Current progress in the advancement of energy‐storage devices is the most important factor that will allow the scientific community to develop resources to meet the global energy demands of the 21st century. Nanostructured materials can be used as effective electrodes for energy‐storage devices because they offer various promising features, including high surface‐to‐volume ratios, exceptional charge‐transport features, and good physicochemical properties. Until now, the successful research frontrunners have focused on the preparation of positive electrode materials for energy‐storage applications; nevertheless, the electrochemical performance of negative electrodes is less frequently reported. This review mainly focuses on the current progress in the development of tungsten oxide‐based electrodes for energy‐storage applications, primarily supercapacitors (SCs) and batteries. Tungsten is found in various stoichiometric and nonstoichiometric oxides. Among the different tungsten oxide materials, tungsten trioxide (WO3) has been intensively investigated as an electrode material for different applications because of its excellent charge‐transport features, unique physicochemical properties, and good resistance to corrosion. Various WO3 composites, such as WO3/carbon, WO3/polymers, WO3/metal oxides, and tungsten‐based binary metal oxides, have been used for application in SCs and batteries. However, pristine WO3 suffers from a relatively low specific surface area and low energy density. Therefore, it is crucial to thoroughly summarize recent progress in utilizing WO3‐based materials from various perspectives to enhance their performance. Herein, the potential‐ and pH‐dependent behavior of tungsten in aqueous media is discussed. Recent progress in the advancement of nanostructured WO3 and tungsten oxide‐based composites, along with related charge‐storage mechanisms and their electrochemical performances in SCs and batteries, is systematically summarized. Finally, remarks are made on future research challenges and the prospect of using tungsten oxide‐based materials to further upgrade energy‐storage devices.

“…Although WO 3 is mostly known within the field of electrochromic devices [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ], and photovoltaics [ 29 ], it also serves as a negative electrode material for Li-ion batteries [ 22 , 30 , 31 , 32 , 33 ]. Though the gravimetric capacity of this electrode material is mediocre, the volumetric energy density is higher than most other oxide electrode materials.…”

“…Though the gravimetric capacity of this electrode material is mediocre, the volumetric energy density is higher than most other oxide electrode materials. For instance, the volumetric density of WO 3 is 604 mAh·cm −3 [ 33 , 34 ], whereas the Li 4 Ti 5 O 12 (LTO) has a capacity of only 228 mAh·cm −3 [ 5 ]. For all-solid-state batteries the latter is arguably the most important device parameter.…”

“…Furthermore, as is the case for LTO, WO 3 only shows a small volume change during lithiation [ 35 ]. The volume change proved to yield no practical issues for thin films up to 100 cycles [ 33 ]. In addition, the choice for WO 3 is related to the fact that the structure can crystallize at temperatures below 300 °C [ 24 , 36 ], which makes it interesting from a device integration point view.…”

“…Finally, WO 3 exhibits an intrinsic advantage related to the compatibility with the solid-electrolyte material. With a relative high (de)intercalation voltage for a negative electrode material—ranging from 1.5 to 3 V vs. Li/Li + [ 22 , 29 , 30 , 33 ]—WO 3 is compatible with the electrochemically relatively unstable LLT electrolyte [ 33 ]. The latter material suffers from a Ti 4+ reduction while cycling below 1.5 V vs. Li + /Li, making it unsuitable for many negative electrode materials such as lithium and graphite [ 3 ].…”

By ultrasonic spray deposition of precursors, conformal deposition on 3D surfaces of tungsten oxide (WO 3 ) negative electrode and amorphous lithium lanthanum titanium oxide (LLT) solid-electrolyte has been achieved as well as an all-solid-state half-cell. Electrochemical activity was achieved of the WO 3 layers, annealed at temperatures of 500 • C. Galvanostatic measurements show a volumetric capacity (415 mAh·cm −3 ) of the deposited electrode material. In addition, electrochemical activity was shown for half-cells, created by coating WO 3 with LLT as the solid-state electrolyte. The electron blocking properties of the LLT solid-electrolyte was shown by ferrocene reduction. 3D depositions were done on various micro-sized Si template structures, showing fully covering coatings of both WO 3 and LLT. Finally, the thermal budget required for WO 3 layer deposition was minimized, which enabled attaining active WO 3 on 3D TiN/Si micro-cylinders. A 2.6-fold capacity increase for the 3D-structured WO 3 was shown, with the same current density per coated area.

Flexible and wearable electronic devices hold great potential in electronic skins, health monitoring systems and soft robotics. Among them, flexible strain sensors with high performance are key components for wearable health monitoring devices. However, the facile and controllable preparation of highly sensitive sensors still faces significant challenges. By virtue of excellent conductivity of 2D transition metal carbids (MXenes), this work reports a facile and low‐cost fabrication strategy for large‐scale production of strain sensors. The sensitive layer is deposited on flexible interdigital electrodes by ultrasonic nebulization of Ti3C2Tx nanosheets. By controlling the nebulization time, different thicknesses of Ti3C2Tx films has a great influence on the performance of strain sensors. The Ti3C2Tx‐based strain sensor exhibits good sensing performances such as high GF (19.1) in the low strain range (≈0.25%–1.14%), short response time (0.7 s), and stable durability (over 1000 cycles). In practice, the potential applications of the strain sensor in sound frequency detection, human physiological signal monitoring and facial expression recognition are demonstrated. Finally, this work integrates the strain sensor with a miniaturized analyzer to assemble a wearable motion monitoring device for mobile healthcare. This study provides a facile strategy for fabricating flexible strain sensors in the field of wearable electronics.
