“…More importantly, formation of the metastable hexagonal phase of WO 3 was possible, mainly through the hydrothermal method. Furthermore, Wu and Yao fabricated WO 3 nanotube bundles through the hydrothermal method . As an anode material, WO 3 nanotube bundles provided an areal capacitance of 2575 mF cm −2 at a current density of 3 mA cm −2 , a specific capacitance of 615.7 F g −1 at a current density of 1 A g −1 , and a cyclic stability of 85.1 % over 6000 cycles.…”

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.

“…Cyclic voltammetry (CV) was performed to research the electrochemical performance of WP/CC and CC under the charge/discharge process (Figure a and Figure S4, Supporting Information). In the first cycle, a cathodic peak is observed at 1.6 V, resulting from the surface residual species . A subsequent broad peak appeared at 1.0 V but disappeared in the following cycles; this is attributed to the decomposition of electrolyte and the formation of a solid electrolyte interphase .…”

The design and development of electrode materials with high specific capacity and long cycling life for sodium‐ion batteries (SIBs) is still a critical challenge. In this communication, we report the development of tungsten phosphide (WP) nanowire on carbon cloth (WP/CC) as an anode for SIBs. The WP/CC exhibits superior sodium storage capability with 502 mA h g−1 at 0.1 A g−1. Moreover, this anode is capable of delivering a long lifespan at 2 A g−1 with an excellent capacity retention of 99 % after 1000 cycles.

is very significant for renewable energy source systems benefiting from plentiful water resource and high purity hydrogen production. It contains two half reactions, that is hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). [5][6][7] However, the efficiency of overall water splitting largely lowers due to the kinetically sluggish OER. [8,9] Developing highly active and cost-effective catalysts is very essential to improve the energy conversion efficiency. [10] Currently, precious metal electrode materials such as Pt and RuO 2 /IrO 2 have been studied due to their superior electrocatalytic performance for HER and OER. [11,12] However, the scarcity, high price, and poor durability seriously restrict their practical applications. Therefore, highly efficient nonprecious metal catalysts for HER and OER are required to expedite the reaction kinetics and lower the overpotential. Transition metal oxides have been widely investigated as promising electrocatalysts for overall water splitting. Among various materials, spinel-structured NiCo 2 O 4 has received considerable interest because of its low cost, abundance, and excellent electrical conductivity. [13,14] For example, Liu and coworkers prepared hierarchical NiCo 2 O 4 hollow microcuboids through assembling porous nanowire subunits for overall water splitting. The as-fabricated products show the overpotential of 300 and 110 mV for OER and HER, respectively, and a cell voltage of 1.65 V at 10 mA cm −2 . [15] Bao et al. synthesized Ni x Co 3−x O 4 nanoneedle arrays on Ni foam through a simple hydrothermal route, the as-prepared products exhibit the overpotential of 320 mV for OER and 170 mV for HER at 10 mA cm −2 . [16] However, intrinsic poor conductivity of metal oxides usually leads to a low current density. Therefore, to prepare hybrid-structured electrode materials by combining high conductivity materials or element doping has been considered an effective strategy. For instance, Tu et al. fabricated hierarchical NiCo 2 O 4 /Ni 2 P core-shell nanocone arrays on Ni foam as a bifunctional catalyst for overall water splitting. The asobtained product shows the overpotential of 250 mV for OER and a cell voltage of 1.59 V at 10 mA cm −2 . [17] Liu and co-workers reported Fe-doped NiCo 2 O 4 @HNCP nanosheets through a simple hydrothermal approach. The as-synthesized electrodes exhibit high OER and HER activities with overpotentials of To rationally design hybrid structures with unique surface/interface features is very significant due to their multi-functionalization in energy storage and conversion systems. Generally, single metal oxide as electrode material is still unsatisfactory for its slow electron transportation and inevitable structural collapse. To address these issues, sulfur element-induced interface-tailoring hybrid NiCo 2 O 4 @NiMo 2 S 4 nanosheet structures with high electrochemical activity are reported through a simple vulcanization process of NiCo 2 O 4 @NiMoO 4 nanosheets. The hybrid NiCo 2 O 4 @NiMo 2 S 4 structure presents excellent...
