“…This suggests that the recent‐developed V 2 O 5 electrodes have acceptable capacity performance in all three insertion modes. Meanwhile, few results with advanced capacity performance which obviously exceed the theoretical values can be found for all three modes. The unique as‐fabricated porous, hierarchical, or high‐specific‐surface‐area nanostructures as well as the small loaded current are the key points to obtain such exceptional performance.…”

deficiency. The exclusive research and industrial focus on the development of new energy sources cannot meet the current energy demands. The main reason is lack of efficient storage of the collected energy. Because the consumption rate of generated energy usually cannot be synchronized with the rate of generation. Fortunately, this problem has received attention from researchers and engineers around the world. Electrochemical energy storage devices (EESDs) [1,2] are competitive candidates for energy storage. Lithiumion batteries (LIBs), [3][4][5][6][7][8][9][10][11] electron double layer capacitors (EDLCs) as well as pseudocapacitors (PCs), [12][13][14][15][16][17] lithium-sulfur (Li-S) batteries, [18][19][20][21][22] lithium-air (Li-air) or lithium-oxygen (Li-O 2 ) batteries, [23][24][25][26][27][28][29] sodium-ion batteries, [30][31][32][33] magnesium-ion batteries, [34] lithium solid state batteries, [35] among others are currently popular EESDs. Among those devices, lithium-ion batteries are of great interest. Since being initially commercialized by Sony, Inc. in 1990, [36] for more than a quarter of a century, the lithium-ion battery has become a popular, portable, and rechargeable second battery used in various applications such as personal electronic devices, [37] electric vehicles, [38] hybrid electric vehicles, [39] and smart grids. [40] To date, it is still needed to further improve the electrochemical performance of lithium-ion batteries. The fabrication of novel and reliable electrode materials is critical for further development of better lithium-ion batteries.A lithium-ion battery cell usually includes components of a solid-state positive electrode (cathode), a solid-state negative electrode (anode), some lithium-ion included liquidstate electrolyte (can be either non-aqueous or aqueous [41] ), a polymeric separator, and a pair of the current collectors with encapsulated cases. [3] If an external voltage applied to both electrodes, lithium ions are deintercalated from cathode to anode through the electrolyte, so called the charging process; when there is an external loading applied to both electrodes, lithium ions are intercalated into unlithiated cathode from lithiated anode through the electrolyte again, i.e., the discharging process. [3,39,42] The discharging procedure of a LIB cell is shown in Figure 1. [39] The role of the porous separator is to prevent the short circuit inside a cell. As the most significant components of one lithium-ion battery cell, the properties of both cathode and anode materials determine the electrochemical energy storage ability of the cell. Therefore, the selection of Vanadium pentoxide (V 2 O 5 ) has played important roles in lithium-ion batteries due to its unique crystalline structure. To assist researchers understanding the roles this material plays, a comprehensive and critical review is conducted based on about 250 publications. Here, we report basics and applications of micro-and nano-materials of V 2 O 5 and V 2 O 5 -based composites. The comparative and stati...

“…[23][24][25] Among the oxides materials, manganese oxide create a center of attention more due to the merits of natural abundance, low toxicity, structural diversity and multi valance nature. [26][27][28] It has the potential to impact in various fields like catalysis, [10,[29][30][31] supercapacitors, [32,33] and metal-air batteries [5,6] etc. In the recent years, manganese oxides have attracted a great deal of attention towards bifunctional electrocatalyst due to their unique structures and physicochemical properties.…”

In this work, a hard‐template‐based nano‐replication process is employed to prepare mesoporous MnO2 materials. We adopted four silica materials, namely, SBA‐15, KIT‐6, MCM‐41, and MCM‐48 as templates to prepare MnO2 materials by using a nanocasting route. The structural characteristics of the resultant MnO2 materials were thoroughly investigated by using XRD, BET, FESEM, HR‐TEM, XPS, and Raman techniques. All studies confirmed the replication of porous MnO2 nanostructures from silica supports in β‐crystallographic form. By employing X‐ray absorption near‐edge structure (XANES) and extended X‐ray absorption fine structure (EXAFS), we identified the existence of Mn and oxygen vacancies in the developed MnO2 material. The hydrodynamic linear sweep voltammetric technique was employed to demonstrate the efficient oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) activity of the catalyst in 0.1 M KOH solution. The KIT‐6‐derived MnO2 nanostructure displayed equal activity to the benchmark catalyst RuO2. This work lays a foundation to prepare and employ ordered mesoporous MnO2 materials as OER/ORR catalysts, which have potential applications in electrochemical energy conversion and storage devices.

“…This result is in conformity with the Ppy synthesized by various methods as reported in the literature. [29] In case of nanocomposites, Ag@Ppy-MA, the corresponding amorphous matrix of Ppy was observed with the same broad shape as in the copolymer. It was also observed that the diffraction peaks with high intensities appear at angles corresponding to Ag crystal plains at 37.5°(111), 43.6°(200), 63.8°(220), and 76.8°(311), which may be because of the silver nanoparticles.…”

Pyrrole and methyl anthranilate were copolymerized in different molar ratios in the presence of, H2O2, and FeSO4 at ambient temperature and pressure to obtain efficient conducting copolymers, Ppy‐MA. These conducting copolymers, Ppy‐MA, were in situ reacted with silver nanoparticles to generate nanocomposites, Ag@Ppy‐MA, which exhibit enhanced electrical conductivity. The spectra and morphology of different copolymers, Ppy‐MA, and their nanocomposites, Ag@Ppy‐MA, were analyzed using Fourier transform infrared, SEM, tunneling electron microscopy, X‐ray diffraction, thermogravimetric analysis, and differential thermal analysis. These studies have shown that the nanocomposites, Ag@Ppy‐MA, are thermally more stable and good electrical conductors as compared with their copolymers, Ppy‐MA. The antibacterial activity of the copolymers, Ppy‐MA, prepared from different monomer ratios and their nanocomposites, Ag@Ppy‐MA, has been carried out using disk diffusion method. The copolymers, Ppy‐MA, and its nanocomposites, Ag@Ppy‐MA, were screened against the standard drug Ciprofloxacin. The results clearly suggest that the nanocomposites, Ag@Ppy‐MA, are better antibacterial agent as compared with their copolymers, Ppy‐MA. Copyright © 2016 John Wiley & Sons, Ltd.
