Abstract ：
Micro-nanostructured electrode materials are characterized by excellent performance in various secondary batteries. In this study, a facile and green hydrothermal method was developed to prepare amorphous vanadium-based microspheres on a large scale. Hollow V2O5 microspheres were achieved, with controllable size, after the calcination of amorphous vanadium-based microspheres and were used as cathode materials for lithium-ion batteries. As the quantity of V2O5 microspheres increased, the electrode performance improved, which was ascribed to the smaller charge transfer impedance. The discharge capacity of hollow V2O5 microspheres could be up to 196.4 mAhg(-1) at a current density of 50 mAg(-1) between 2.0 and 3.5 V voltage limits. This sheds light on the synthesis and application of spherical electrode materials for energy storage.

Abstract ：
A simple and versatile method was developed to prepare hollow Paramontroseite VO2 microspheres. Hollow VO2 microspheres were formed via an Ostwald ripening mechanism. The morphology, crystalline structure and electrochemical performance were systematically studied. It was found that hollow Paramontroseite VO2 microspheres can be used as stable anode and cathode materials for lithium ion batteries with acceptable rate cycling performance. In addition, the discharge capacities of hollow paramontroseite VO2 microsphere-based negative electrodes were found to reach 384.2 mAhg(-1) at a current density of 750 mAg(-1). A discharge capacity of 195.6 mAg(-1) was achieved when the microspheres were used as a cathode material for lithium-ion batteries at a current density of 20 mAg(-1). Vanadium based dual electrode materials are seldom reported in the literature.

Abstract ：
It is important to discover novel electrode materials and optimize the performance of existing cathode materials for aqueous zinc-ion batteries. Here, two V2O5 center dot 3H(2)O composites are achieved via a facile hydrothermal route. One is flake-like V2O5 center dot 3H(2)O built up with multiple platelets with surface defects in parallel or normal positions, and the other is V2O5 center dot 3H(2)O composite microflowers built up with multilayered microplatelets in a radial position without surface defects. Both can be used as cathode materials for aqueous zinc-ion batteries. The former showed higher discharge capacity and better rate performance. The electrode of V2O5 center dot 3H(2)O flakes exhibits stable discharge capacity at current densities of 50, 100, 250, 500, 750, 1000, 1500 and 50 mAg(-1). The capacity retention is 90.3% after 80 cycles from 237.2 mAhg(-1) to 214.1 mAhg(-1). While V2O5 center dot 3H(2)O microflowers do not exhibit stable discharge capacity at current densities of 50, 100, 250, 500, 750, 1000, 1500 and 50 mAg(-1). The capacity retention is 47.96% after 80 cycles from 223.9 mAhg(-1) to 107.4 mAhg(-1). The difference in cycling performance can be ascribed to surface defects and different compositions.

Abstract ：
Monolayer carbon materials, including monolayer graphene, carbon nanohorn, single-wall nanotube, monolayer giant fullerenes and monolayer amorphous carbon, have been attracting great interest due to their unique physicochemical properties, and new methods for facile and large scale preparation of monolayer carbons are challenging and of great importance. Herein, N-P-doped monolayer carbon foam were prepared by a direct pyrolysis method. The aerogel-like carbon foam was composed of connected and/or fused monolayer carbon nanoshells with the size of 2-6 nm, and the hierarchically porous structure gave rise to an extremely large surface area of 2570 m(2) g(-1). The carbon foam was preliminarily tested as catalyst support and negative electrode material for lithium ion battery and exhibited good performance. This study would inspire further study on formation mechanism of monolayer carbon, as well as modification and functionalization of the monolayer carbon nanoshells for application in catalysis and energy conversion and storage.

Abstract ：
NH4V4O10 based ammonium vanadium bronze has been widely investigated as a cathode material for lithium-ion batteries. A V4O10 group based H6V4O10 might be a potential anode material due to its high hydrogen content and similar composition. Microspheres modified by loosely distributed nanoparticles showed higher discharge capacity and better cycling stability than those composed of tightly packed micro-blocks for lithium-ion batteries and zinc-ion batteries. The former can steadily cycle at current densities of 400 mA g(-1) for 1000 cycles with a capacity of up to 387 mA h g(-1). The discharge capacity of aqueous zinc-ion batteries can be up to 238.8 mA h g(-1) with a capacity retention of 87.8% after 26 cycles. The improved electrochemical performance can be ascribed to the nanoparticles modifying the loose surface, which promotes ion and electron transfer.

Abstract ：
Antimony oxychloride (Sb8O11Cl2) microrods with the diameter of about 100 nm are synthesized by a facial solvothermal reaction. And the material of Sb8O11Cl2 is applied as an anode material for sodium-ion batteries for the first time. It can deliver 723.4, 500.6, and 425.5 mA h g(-1) after 20 cycles under current densities of 10, 30, and 50 mA g(-1), respectively. Besides, the rate performance is also surprising (specific capacities of 517.4, 411.6, 247.8, and 191.2 mA h g(-1) are achieved at the current densities of 30, 50, 100, and 200 mA g(-1), respectively). Furthermore, the Sb8O11Cl2 electrode is of two very appropriate discharge plateaus (0.4 and 1.3 V) during sodiation/desodiation process, which is very critical for the long-term development of the sodium-ion batteries. In this work, a novel electrode material is presented, and it will encourage more researchers to explore Sb8O11Cl2 deeply due to its outstanding capacity and reversible performance.

Abstract ：
It is important to discover new, cheap and environmental friendly coordination polymer electrode materials for lithium-ion batteries. Zinc 2,6-pyridilinedicarboxylate particles show better cycling stability and higher discharge capacity than 2,5-pyridilinedicarboxylate micro-platelets when they are firstly tested as anode materials for lithium-ion batteries. The former can steadily cycle at current densities of 750, 1000 and 2000 mA g(-1). It is also stable in multiple insertion/extraction processes at current densities of 750, 1500, 2000, 2500, 3000, and 750 mA g(-1), and the capacity retention is 77.9% after 60 cycles. While the latter is apt to show good cycling performance at smaller discharge current density. (C) 2016 Elsevier Inc. All rights reserved.
