“…LiV3O8 also displays a layered structure consisting of VO6 octahedra and distorted VO5 trigonal bipyramids grouped as sheets, which share edges and corners [362]. A number of LiV3O8 nanostructures have been reported in the literature recently, including nanorods [363][364][365][366][367][368], nanowires [369], nanosheets [370,371], and nanoparticles [372]. Xu et al [369], have recently synthesised one of the first large-scale examples of LiV3O8 nanowires by a topotactic conversion of structurally analogous H2V3O8 nanowires.…”

Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.

“…It is well understood that the electrochemical properties of lithium vanadium oxide are largely depend on the preparation method. Therefore, many preparation methods have been studied to LiV 3 O 8 with an aim to improve its electrochemical performance, such as spray pyrolysis method [5], sol-gel method [6][7][8], microwave-assisted synthesis [9], ultrasonic treatment [4] and hydrothermal synthesis [10]. Recently, Liu et al [11] employed home-made VO2 nanorods as the vanadium precursor to prepare the LiV3O8 cathode materials.…”

“…It is well-know that the electrochemical performances of LVO depends highly upon preparation methods and post-processing techniques [8,9]. Therefore, several synthetic routes have been developed to further enhance the electrochemical performance of LVO, such as microwave synthesis [2], sol-gel synthesis [10,11,12,13,14], spray pyrolysis synthesis [15,16], hydrothermal synthesis [2,17], and solid-state reactions [18,19]. However, until now, bare LVO still suffers from low capacity retention and poor rate performance on account of the phase transformation and slow kinetics during the charge-discharge process [20,21,22], which hinders its practical applications.…”

LiV3O8/polytriphenylamine composites are synthesized by a chemical oxidative polymerization process and applied as cathode materials for rechargeable lithium batteries (RLB). The structure, morphology, and electrochemical performances of the composites are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, galvanostatic discharge/charge tests, and electrochemical impedance spectroscopy. It was found that the polytriphenylamine particles were composited with LiV3O8 nanorods which acted as a protective barrier against the side reaction of LiV3O8, as well as a conductive network to reduce the reaction resistance among the LiV3O8 particles. Among the LiV3O8/polytriphenylamine composites, the 17 wt % LVO/PTPAn composite showed the largest d100 spacing. The electrochemical results showed that the 17 wt % LVO/PTPAn composite maintained a discharge capacity of 271 mAh·g−1 at a current density of 60 mA·g−1, as well as maintaining 236 mAh·g−1 at 240 mA·g−1 after 50 cycles, while the bare LiV3O8 sample retained only 169 and 148 mAh·g−1, respectively. Electrochemical impedance spectra (EIS) results implied that the 17 wt % LVO/PTPAn composite demonstrated a decreased charge transfer resistance and increased Li+ ion diffusion ability, therefore manifesting better rate capability and cycling performance compared to the bare LiV3O8 sample.
