Highly improved rechargeable stability for lithium/silver vanadium oxide battery induced via Electrospinning Technique
Journal of Materials Chemistry, 2020Co-Authors: Yongzhi Wu, Xuan Zhao, M V Reddy, Shengjie Peng, B V R Chowdari, Seeram RamakrishnaAbstract:The Electrospinning Technique and the hydrothermal method are two well-known ways to fabricate nanostructures effectively for battery applications. Herein we report a novel preparation of β-Ag0.33V2O5 nanostructures via an Electrospinning Technique followed by a hydrothermal process. These electrospun-derived materials are composed of single crystalline nanorods with self-limited aggregation verified by XRD, SEM and TEM results. Characterized by electroanalytical Techniques, β-Ag0.33V2O5 nanostructures show an initial high capacity ∼250 mA h g−1 and improved cycling stability with a capacity loss of only ∼1 mA h g−1 per cycle after 30 runs at a current of 20 mA g−1. The materials exhibit a moderate capacity drop at higher charge/discharge rates. Not only is this among the best cycling performance reported so far for the silver vanadium oxide (SVO) series, but the novel atomic inter-planar construction and unique nano-morphology demonstrate a promising road to enhance the cycling stability for electrode materials using the Electrospinning Technique.

facile approach to prepare porous casno3 nanotubes via a single spinneret Electrospinning Technique as anodes for lithium ion batteries
ACS Applied Materials & Interfaces, 2012Co-Authors: Linlin Li, Shengjie Peng, Jin Wang, Yan Ling Cheah, Yah Wen Ko, Chui Ling Wong, Madhavi SrinivasanAbstract:CaSnO3 nanotubes are successfully prepared by a single spinneret Electrospinning Technique. The characterized results indicate that the well-crystallized one-dimensional (1D) CaSnO3 nanostructures consist of about 10 nm nanocrystals, which interconnect to form nanofibers, nanotubes, and ruptured nanobelts after calcination. The diameter and wall thickness of CaSnO3 nanotubes are about 180 and 40 nm, respectively. It is demonstrated that CaSnO3 nanofiber, nanotubes, and ruptured nanobelts can be obtained by adjusting the calcination temperature in the range of 600–800 °C. The effect of calcination temperature on the morphologies of electrospun 1D CaSnO3 nanostructures and the formation mechanism leading to 1D CaSnO3 nanostructures are investigated. As anodes for lithium ion batteries, CaSnO3 nanotubes exhibit superior electrochemical performance and deliver 1168 mAh g–1 of initial discharge capacity and 565 mAh g–1 of discharge capacity up to the 50th cycle, which is ascribed to the hollow interior structu...

anodic electrochemical performances of mgco2o4 synthesized by oxalate decomposition method and Electrospinning Technique for li ion battery application
Materials Research Bulletin, 2016Co-Authors: M V Reddy, Devendrasinh Darbar, S Sundarrajan, R Pattabiraman, S Ramakrishna, B V R ChowdariAbstract:Abstract Magnesium cobalt oxide, MgCo2O4 was synthesized by oxalate decomposition method and Electrospinning Technique. The electrochemical performances, structures, phase formation and morphology of MgCo2O4 synthesized by both the methods are compared. Scanning electron microscope (SEM) studies show spherical and fiber type morphology, respectively for the oxalate decomposition and Electrospinning method. The electrospun nanofibers of MgCo2O4 calcined at 650 °C, showed a very good reversible capacity of 795 mAh g−1 after 50 cycles when compared to bulk material capacity of 227 mAh g−1 at current rate of 60 mA g−1. MgCo2O4 nanofiber showed a reversible capacity of 411 mAh g−1 (at cycle) at current density of 240 mA g−1. Improved performance was due to improved conductivity of MgO, which may act as buffer layer leading to improved cycling stability. The cyclic voltammetry studies at scan rate of 0.058 mV/s show main cathodic at around 1.0 V and anodic peaks at 2.1 V vs. Li.
