“…Electrospinning has also been employed recently in the synthesis of 1D V2O5 nanowires which display enhanced Li-ion performance [326,328,329,332]. For example, Mai et al [329], prepared ultra-long V2O5 nanowires with diameters between 100-200 nm and lengths of several millimetres, by electrospinning a solution of poly (vinyl alcohol) and NH4VO3 under an applied voltage of 20 kV.…”

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.

“…And transition metals have been found to have the capability to accomplish this as they can react with more than one lithium ions per redox ion [26]. Recently, a variety of cathode materials such as LiFeO 4, [9,27,28] LiFePO 4 [27,29,30] and LiMn 2 O 4 [31e34] have been reported to have advantages over LiCoO 2 but they still deliver limited capacities in the range of 100e170 mAhg À1 leading to LIBs specific energy densities of~200 Whkg À1 [26]. Therefore, many other efforts are pressingly required to develop high energy and high power cathode materials to further enhance the LIBs energy densities for large scale EV and renewable energy storage applications [3,19,35].…”

Electrospinning has attracted tremendous attention in the design and preparation of 1D nanostructured electrode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (NIBs), due to the versatility and facility. In this review, we present a comprehensive summary of the development of electrospun electrode nanomaterials for LIBs and NIBs, and a brief introduction about electrode materials beyond LIBs and NIBs. By summarizing various electrochemical active materials, this review focuses on the evolution in structures and the constitution of electrospun electrode materials. In detail, a variety of electrospun anode and cathode materials of LIBs and NIBs have been properly discussed, respectively. Finally, the current progress in the electrospun electrode materials is well reviewed and the development direction is also pointed out. We believe that in the nearly future, electrospun electrode materials would be applied in commercial LIBs and promote the advance in NIBs. And we hope that this review could be helpful in the design and fabrication of electrospun hierarchical materials for other advanced energy-storage devices.
