  • an aqueous symmetric Sodium Ion Battery with nasicon structured na3mnti po4 3
    Angewandte Chemie, 2016
    Co-Authors: Hongcai Gao, John B Goodenough
    Abstract:

    A symmetric Sodium-Ion Battery with an aqueous electrolyte is demonstrated; it utilizes the NASICON-structured Na3MnTi(PO4)3 as both the anode and the cathode. The NASICON-structured Na3MnTi(PO4)3 possesses two electrochemically active transitIon metals with the redox couples of Ti4+/Ti3+ and Mn3+/Mn2+ working on the anode and cathode sides, respectively. The symmetric cell based on this bipolar electrode material exhibits a well-defined voltage plateau centered at about 1.4 V in an aqueous electrolyte with a stable cycle performance and superior rate capability. The advent of aqueous symmetric Sodium-Ion Battery with high safety and low cost may provide a solutIon for large-scale statIonary energy storage.

  • a Sodium Ion Battery with a low cost cross linked gel polymer electrolyte
    Advanced Energy Materials, 2016
    Co-Authors: Hongcai Gao, Weidong Zhou, Kyusung Park, John B Goodenough
    Abstract:

    The design of a Sodium-Ion rechargeable Battery with an antimony anode, a Na3V2(PO4)3 cathode, and a low-cost composite gel-polymer electrolyte based on cross-linked poly(methyl methacrylate) is reported. The applicatIon of an antimony anode, on replacement of the Sodium metal that is commonly used in Sodium-Ion half-cells, reduces significantly the interfacial resistance and charge transfer resistance of a Sodium-Ion Battery, which enables a smaller polarizatIon for a Sodium-Ion full-cell Sb/Na3V2(PO4)3 running at relatively high charge and discharge rates. The incorporatIon of the gel-polymer electrolyte is beneficial to maintain stable interfaces between the electrolyte and the electrodes of the Sodium-Ion Battery at elevated temperature. When running at 60 °C, the Sodium-Ion full-cell Sb/Na3V2(PO4)3 with the gel-polymer electrolyte exhibits superior cycling stability compared to a Battery with the conventIonal liquid electrolyte.

Due to fast Ionic/electronic transport kinetics even at −25 °C, the cathode shows an outstanding low-temperature performance in terms of specific energy, high-rate capability, and cycle life, providing a practical Sodium-Ion Battery powering an electric vehicle in frigid regIons.

  • na3v2o2 po4 2f graphene sandwich structure for high performance cathode of a Sodium Ion Battery
    Physical Chemistry Chemical Physics, 2013
    Co-Authors: Maowen Xu, Long Wang, Xin Zhao, Jie Song, Hui Xie, Yuhao Lu, John B Goodenough
    Abstract:

    A Na3V2O2(PO4)2F/reduced-graphene-oxide (RGO) sandwich structure has been synthesized by a facile one-step solvothermal method. Cubic Na3V2O2(PO4)2F nanoparticles are homogeneously trapped between conductive RGO sheets during its growth and assembled into a compact sandwich structure, which allows the electrically insulating Na3V2O2(PO4)2F nanoparticles to be wired up to a current collector through the underlying graphene conducting layers. As a Sodium-insertIon cathode material, the structure exhibits a high reversible capacity of 120 mA h g−1 at a discharge rate of C/20 with a capacity retentIon of 100.4 mA h g−1 at 1 C and an excellent cyclic retentIon of 91.4% after the 200th cycle at C/10. These results highlight the importance of anchoring Na3V2O2(PO4)2F on a conducting scaffold for maximum utilizatIon of the electrochemically active Na3V2O2(PO4)2F particles in a high-performance Sodium-Ion Battery.

  • a stable 3 v all solid state Sodium Ion Battery based on a closo borate electrolyte
    Energy and Environmental Science, 2017
    Co-Authors: Leo Duchene, Rubensimon Kuhnel, Evelyn Stilp, Cuervo E Reyes, Arndt Remhof, Hansrudolf Hagemann, Corsin Battaglia
    Abstract:

    We report on a particularly stable 3 V all-solid-state Sodium–Ion Battery built using a closo-borate based electrolyte, namely Na2(B12H12)0.5(B10H10)0.5. Battery performance is enhanced through the creatIon of an intimate cathode–electrolyte interface resulting in reversible and stable cycling with a capacity of 85 mA h g−1 at C/20 and 80 mA h g−1 at C/5 with more than 90% capacity retentIon after 20 cycles at C/20 and 85% after 250 cycles at C/5. We also discuss the effect of cycling outside the electrochemical stability window and show that electrolyte decompositIon leads to faster though not critical capacity fading. Our results demonstrate that owing to their high stability and conductivity closo-borate based electrolytes could play a significant role in the development of a competitive all-solid-state Sodium–Ion Battery technology.

    Advanced Science, 2017
    Co-Authors: Qingkai Xu, Yaokun Pang, Lei Li, Jiulin Wang, Chi Zhang
    Abstract:

    Storing energy harvested by triboelectric nanogenerators (TENGs) from ambient mechanical motIon is still a great challenge for achieving low-cost and environmental benign power sources. Here, an all-solid-state Na-Ion Battery with safe and durable performance used for efficient storing pulsed energy harvested by the TENG is demonstrated. The solid-state Sodium-Ion batteries are charged by galvanostatic mode and pulse mode with the TENG, respectively. The all-solid-state Sodium-Ion Battery displays excellent cyclic performance up to 1000 cycles with a capacity retentIon of about 85% even at a high charge and discharge current density of 48 mA g−1. When charged by the TENG, an energy conversIon efficiency of 62.3% is demonstrated. The integratIon of TENGs with the safe and durable all-solid-state Sodium-Ion batteries is potential for providing more stable power output for self-powered systems.

    Abstract:

    Sodium-Ion Battery is most alternative advanced technology for portable electronics devices. In our present study, we are dealing with a suitable cathode material for Sodium-Ion Battery which can deliver high capacity as well as good stable cyclic performance. We prepared Sodium vanadium phosphate (Na3V2(PO4)3) by the simple solvothermal process. The as-prepared electrode is characterized by X-ray diffractIon (XRD) analysis, field emissIon gun scanning electron microscope (FEG-SEM). The cathode material gives very high reversible discharge capacity of 123 mAh g−1 at current rate C/6 and has a very good stable cyclic performance. After 50 cycles, we achieved a discharge capacity of 115 mAh g−1 with same current rate, almost 94% capacity retentIon.

    Carbon, 2019
    Co-Authors: Anish Raj K, Manas Ranjan Panda, Dimple P Dutta, Sagar Mitra
    Abstract:

    Abstract Bio-derived porous carbon has been synthesized from the seeds of Litchi chinensis (lychee) by a simple, economic and environment-friendly approach. The material is characterized by different physical characterizatIon techniques, the XRD and Raman spectra revealed the mixed amorphous and graphitic nature of the carbon whereas FE-SEM, HRTEM, and BET analysis proved its highly porous nature. While testing its applicatIon in Battery against Sodium metal it provided a superficial storage and transport path for Sodium-Ions. The Sodium-Ion adsorptIon mechanism has been well studied by ex-situ experimental techniques. The biocarbon anode further showed an excellent rate capability and a superior electrochemical reversible specific capacity of ∼146 mAh g−1 at 0.2 A g−1 current density after 100 cycles. The biocarbon anode is used to construct a full-cell lab prototype for Sodium-Ion batteries (SIBs) with respect to Sodium vanadium phosphate (NVP) as cathode, and observed the specific capacity of ∼266 mAh g−1 at 0.1 A g−1 current density for 50 cycles. These studies reveal the applicatIon of naturally abundant biomass-derived biocarbon as a potential anode material for Sodium-Ion Battery applicatIon. The constructIon and demonstratIon of SIB coin cell with NVP cathode and biocarbon anode open up the possibility of its applicatIons in future.

    Co-Authors: Ananta Sarkar, Mofasser Mallick, Manas Ranjan Panda, Satish Vitta, Sagar Mitra
    Abstract:

    Sodium-Ion Battery is the most popular alternative to lithium-Ion energy storage system due to its low cost and huge abundant resources throughout the world. Although recent literature showed cathode materials for Sodium Ion Battery performs almost equivalent to lithium-Ion counterpart but the anode of this Sodium-Ion Battery is in premature state. Here, we introduced free-standing copper telluride (Cu2Te), a new anode materials for Sodium-Ion Battery. For making the electrode we did not use any conductive carbon or current collector which increase the volumetric density as well as reduce the cost of the cell. This metallic Cu2Te alloy exhibited a high reversible capacity of ∼275 mAh g−1 at 50 mA g−1 current density and ∼200 mAh g−1 at higher current density of 100 mA g−1, operating between 0.1 to 2.0 V.Sodium-Ion Battery is the most popular alternative to lithium-Ion energy storage system due to its low cost and huge abundant resources throughout the world.
