“…Two potential plateaus appeared at 2.2 and 2.7 V in the first cathodic scanning of C‐MoO 3 product, demonstrating the Li ion intercalation reaction in which Li x MoO 3 would form (MoO 3 + x Li + + x e − →Li x MoO 3 ) 27‐28 . Except for the two small peaks, a strong peak at 0.23 V corresponds to the formation of Mo metal and Li 2 O (Li x MoO 3 + y Li + + y e − →Mo + 3Li 2 O) 27‐28 . In the anodic scan procedure, the anodic peaks at 1.3 and 1.8 V can be ascribed to the deintercalation procedure of Li ions.…”

[27][28] In the anodic scan procedure, the anodic peaks at 1.3 and 1.8 V can be ascribed to the deintercalation procedure of Li ions. For the A-MoO 3 samples ( Figure 4B), only one obvious cathodic peak is present at 1.1 V due to the formation of new Li x MoO 3 phase and a SEI layer, similar to other amorphous transition-metal oxides.…”

In this study, crystalline MoO 3 rods and amorphous MoO 3 microsheets were synthesized using a one-step, large-scale, and time-and energy-efficient solution combustion synthesis method. When urea was used as a fuel, ultralong rod-like crystalline MoO 3 with a length over 50 μm was synthesized. In the case of citric acid, an amorphous MoO 3 product with a porous microsheet structure was obtained. As anode materials for lithium-ion batteries, the unique structure of amorphous MoO 3 sample has significant advantages including fast diffusion of lithium ion, providing a lot of active sites for lithium ion storage and stable structure. Thus, the amorphous MoO 3 sample exhibits greater electrochemical performance, a high capacity of 818 mAh g −1 at 0.1 A g −1 in the 100th cycle and 510 mAh g −1 at 1 A g −1 in the 300th cycle, than that of crystalline MoO 3 product. Moreover, this study provides guide for preparing other amorphous and crystalline transition-metal oxides with a pure phase. How to cite this article: Wu H, Zhou S, Tseng C-H, et al.

“…Satyanarayana's group [66] used a facile high-energy ball-milling process followed by ultrasonication method to prepare MoO 3 /rGO composites. Same as above, the composites exhibit better electrochemical performance than just nanostructured due to the increase in surface area and conductivity Although the specific capacities of three samples drop gradually in the first five cycles, the MoO 3 -10 wt % rGO sample still shows higher reversible capacity (568 mA h g −1 at a high current density of 500 mA g −1 even after 100 cycles) than commercially available graphite (Figure 4h) and good rate performance with specific capacity 502 mA h g −1 even at a higher current density of 1000 mA g −1 , and it retained the specific capacity of 853 mA h g −1 as the current density switched from 1000 mA g −1 to 100 mA g −1 (Figure 4i).…”

In order to meet the growing demand for the electronics market, many new materials have been studied to replace traditional electrode materials for energy storage systems. Molybdenum oxide materials are electrode materials with higher theoretical capacity than graphene, which was originally used as anode electrodes for lithium-ion batteries. In subsequent studies, they have a wider application in the field of energy storage, such as being used as cathodes or anodes for other ion batteries (sodium-ion batteries, potassium-ion batteries, etc.), and electrode materials for supercapacitors. However, molybdenum oxide materials have serious volume expansion concerns and irreversible capacity dropping during the cycles. To solve these problems, doping with different elements has become a suitable option, being an effective method that can change the crystal structure of the materials and improve the performances. Therefore, there are many research studies on metal element doping or non-metal doping molybdenum oxides. This paper summarizes the recent research on the application of hetero-element-doped molybdenum oxides in the field of energy storage, and it also provides some brief analysis and insights.

“…MoO 3 has a wide range of applications in many fields such as electrochromics [7][8][9], photochromics [10,11], electrochemical capacitors [12,13], electrocatalytic activities [14,15], gas sensors [16][17][18][19], and lithium-ion batteries [20][21][22][23][24], which makes it a more popular transition metal oxide. Recently, the electrochromic properties of MoO 3 nanomaterials have attracted much attention.…”

Electrochromic Performance and Capacitor Performance of α-MoO3 Nanorods Fabricated by a One-Step Procedure

et al. 2021

In this paper, we propose for the first time the synthesis of α-MoO3 nanorods in a one-step procedure at mild temperatures. By changing the growth parameters, the microstructure and controllable morphology of the resulting products can be customized. The average diameter of the as-prepared nanorods is about 200 nm. The electrochromic and capacitance properties of the synthesized products were studied. The results show that the electrochromic properties of α-MoO3 nanorods at 550 nm have 67% high transmission contrast, good cycle stability and fast response time. The MoO3 nanorods also exhibit a stable supercapacitor performance with 98.5% capacitance retention after 10,000 cycles. Although current density varies sequentially, the nanostructure always exhibits a stable capacitor to maintain 100%. These results indicate the as-prepared MoO3 nanorods may be good candidates for applications in electrochromic devices and supercapacitors.
