“…55 In the subsequent charging-discharging processes, the pristine Zn 2 SnO 4 nanoparticles show the linear capacity fading on continuous processes ensuring that pristine Zn 2 SnO 4 nanoparticles could not be able to accommodate the volume change during charging-discharging processes. 7,56 The In and Ex-Zn 2 SnO 4 electrodes deliver the stable discharge capacity of 467 and 533 mA h g À1 with capacity retention of 53 and 66%, respectively, over 50 cycles. Overall, In-Zn 2 SnO 4 shows higher discharge capacity and better coulombic efficiency than the other electrodes.…”

“…Concerning this, different kinds of energy conversion and storage devices like fuel cells, solar cells, supercapacitors and batteries are being deliberately explored. [5][6][7] However, there are some drawbacks such as (i) large volume expansion/contraction and severe particle aggregation during charging-discharging processes leading to pulverization thus resulting in high irreversible capacity and poor cycling stability, (ii) the Li 2 O formation during charging-discharging process leads to the electrical isolation of anode materials. [1][2][3] It has also been used in electric cars, which may drive upto 100 miles with energy of $30 kW h depending upon their mileages, but the cost of energy is high $$320 per kW h. 4 So, it is mandatory to develop low cost as well as high capacity electrodes for Li-ion batteries.…”

Zinc stannate, Zn 2 SnO 4 nanoparticles are successfully synthesized by a facile hydrothermal method.Subsequently, a layer of carbon is coated on Zn 2 SnO 4 nanoparticles by both in situ and ex situ methods using glucose as a carbon source. The phase purity, carbon content, oxidation state and morphological features are characterized by various techniques. The percentage of carbon present in the Zn 2 SnO 4 is calculated using thermogravimetric analysis. The core-shell structure of Zn 2 SnO 4 @C is revealed through high resolution transmission electron microscope images. The electrochemical performance of the Zn 2 SnO 4 @C is examined by dQ/dV, charge-discharge, rate capability and electrochemical impedance spectroscopy analysis. Among these, the ex situ carbon coated Zn 2 SnO 4 shows superior cycling stability and it delivered a stable specific discharge capacity of 533 mA h g À1 at 700 mA g À1 over 50 cycle. The EIS analysis indicates that the obtained low charge transfer resistance (R ct ) and solid electrolyte interphase (SEI) film resistance (R SEI ) of the ex situ carbon coated Zn 2 SnO 4 controls the SEI film thickness on the outer surface of the active material. Overall, the electrochemical analysis elucidates that the ex situ carbon coated Zn 2 SnO 4 shows an excellent cycling stability and good electronic conductivity compared with carbon free and in situ carbon coated Zn 2 SnO 4 .

“…Recently, rapidly growing demands for energy storage of consumer electric vehicles, hybrid electric vehicles, and grid energy storage have also called for novel high‐performance energy‐storage devices. Among highly promising candidates, lithium‐ion batteries (LIBs) have attracted much attention, owing to their high energy density, high working voltage, low self‐discharge rate, and environment‐friendliness . However, due to its low theoretical specific capacity (372 mA h g −1 ) and safety issues, commercial graphite anode cannot fulfill the ever‐increasing requirements for LIBs in large‐scale applications.…”

1 wileyonlinelibrary.com www.particle-journal.com www.MaterialsViews.com 1D nanostructured metal oxides with porous structure have drawn wide attention to being used as high-performance anode materials for lithiumion batteries (LIBs). This study puts forward a simple and scalable strategy to synthesize porous NiO nanorods with the help of a thermal treatment of metal-organic frameworks in air. The NiO nanorods with an average diameter of approximately 38 nm are composed of nanosized primary particles. When evaluated as anode materials for LIBs, an initial discharge capacity of 743 mA h g −1 is obtained at a current density of 100 mA g −1 , and a high reversible capacity is still maintained as high as 700 mA h g −1 even after 60 charge-discharge cycles. The excellent electrochemical performance is mainly ascribed to the 1D porous structure.Unfortunately, the pulverization of the electrode associated with volume expansion and contraction during the chargedischarge process limits their real-world application. [9] There are many ways to solve this problem. One effective solution is to fabricate porous nanostructure with large surface areas and suitable pores, which can not only effectively improve the diffusion rate of Li + /electrons, but also locally relieve the pressure caused by the volume changes during the lithiation-delithiation process. [10] 1D porous structure with large surface-to-volume ratio and short diffusion length can effectively compromise volume changes during the insertion-extraction of Li + and thus improve the cycling performance. Although the structure has been demonstrated more or less effectively, there is still much room for further improvement.Metal-organic framework (MOF), a novel type of porous material composed of metal ions or clusters and organic ligands, has been extensively researched. MOFs, characterized by various skeletal and well-defined pore structure are suitable for applications in supercapacitor, [11] sensing, [12] adsorption, [13] and drug delivery. [14] Inspired by the high surface areas and tunable structures, MOFs have been considered as prospective precursors to fabricate nanostructured porous metal oxides by simple thermal treatment in air. Through the topological conversion by thermal treatment, the expected metal oxides should be obtained easily with a similar morphology to the nanoscale MOFs precursors and a certain degree of permanent porosity originated from the liberation of gas molecules. Compared with other precursors, MOFs have attracted much attention due to their large surface area (about 7000 m 2 g −1 ), high porosity, low density, controllable structure, and tunable pore size. The pore size of MOFs precursors can be tuned by changing organic ligands, with the largest aperture of 9.8 nm. [15] In this respect, Zhang et al. [16] synthesized Fe 2 O 3 microboxes by onestep thermal decomposition of Prussian blue microcubes; Wu et al. [17] prepared porous CuO hollow octahedral by annealing Cu-MOFs templates; Xu et al. [18] fabricated spindle-like porous α-Fe 2 O 3 ...
