Bi₂Se₃/C Nanocomposite as a New Sodium-Ion Battery Anode Material.

ABSTRACT: Bi₂Se₃ was studied as a novel sodium-ion battery anode material because of its high theoretical capacity and high intrinsic conductivity. Integrated with carbon, Bi₂Se₃/C composite shows excellent cyclic performance and rate capability. For instance, the Bi₂Se₃/C anode delivers an initial capacity of 527 mAh g^-1 at 0.1 A g^-1 and maintains 89% of this capacity over 100 cycles. The phase change and sodium storage mechanism are also carefully investigated.

NaAlTi3O8, A Novel Anode Material for Sodium Ion Battery.

Project description:Sodium ion batteries are being considered as an alternative to lithium ion batteries in large-scale energy storage applications owing to the low cost. A novel titanate compound, NaAlTi3O8, was successfully synthesized and tested as a promising anode material for sodium ion batteries. Powder X-ray Diffraction (XRD) and refinement were used to analyze the crystal structure. Electrochemical cycling tests under a C/10 rate between 0.01 - 2.5 V showed that ~83 mAh/g capacity could be achieved in the second cycle, with ~75% of which retained after 100 cycles, which corresponds to 0.75 Na+ insertion and extraction. The influence of synthesis conditions on electrochemical performances was investigated and discussed. NaAlTi3O8 not only presents a new anode material with low average voltage of ~0.5 V, but also provides a new type of intercalation anode with a crystal structure that differentiates from the anodes that have been reported.

Fe7Se8 encapsulated in N-doped carbon nanofibers as a stable anode material for sodium ion batteries.

Project description:Transition metal chalcogenides especially Fe-based selenides for sodium storage have the advantages of high electric conductivity, low cost, abundant active sites, and high theoretical capacity. Herein, we proposed a facile synthesis of Fe7Se8 embedded in carbon nanofibers (denoted as Fe7Se8-NCFs). The Fe7Se8-NCFs with a 1D electron transfer network can facilitate Na+ transportation to ensure fast reaction kinetics. Moreover, Fe7Se8 encapsulated in carbon nanofibers, Fe7Se8-NCFs, can effectively adapt the volume variation to keep structural integrity during a continuous Na+ insertion and extraction process. As a result, Fe7Se8-NCFs present improved rate performance and remarkable cycling stability for sodium storage. The Fe7Se8-NCFs exhibit practical feasibility with a reasonable specific capacity of 109 mA h g-1 after 200 cycles and a favorable rate capability of 136 mA h g-1 at a high rate of 2 A g-1 when coupled with Na3V2(PO4)3 to assemble full sodium ion batteries.

Spinel rGO Wrapped CoV2O4 Nanocomposite as a Novel Anode Material for Sodium-Ion Batteries.

Project description:Binary mixed transition-based metal oxides have some of the most potential as anode materials for rechargeable advanced battery systems due to their high theoretical capacity and tremendous electrochemical performance. Nonetheless, binary metal oxides still endure low electronic conductivity and huge volume expansion during the charge/discharge processes. In this study, we synthesized a reduced graphene oxide (rGO)-wrapped CoV2O4 material as the anode for sodium ion batteries. The X-ray diffraction analyses revealed pure-phased CoV2O4 (CVO) rGO-wrapped CoV2O4 (CVO/rGO) nanoparticles. The capacity retention of the CVO/rGO composite anode demonstrated 81.6% at the current density of 200 mA/g for more than 1000 cycles, which was better than that of the bare one of only 73.5% retention. The as-synthesized CVO/rGO exhibited remarkable cyclic stability and rate capability. The reaction mechanism of the CoV2O4 anode with sodium ions was firstly studied in terms of cyclic voltammetry (CV) and ex situ XRD analyses. These results articulated the manner of utilizing the graphene oxide-coated spinel-based novel anode-CoV2O4 as a potential anode for sodium ion batteries.

Project description:A novel Bi13S18I2 structure was synthesized using a facile one-pot hydrothermal method and further optimized as an anode material using graphene. The graphene/Bi13S18I2 composite achieved a high discharge capacity with an initial value of 1126.5 mA h g-1 and a high and stable discharge capacity of 287.1 mA h g-1 after 500 cycles compared with pure Bi13S18I2, which derives from the inhibited volume expansion and high electrical conductivity obtained from graphene. In situ XRD was performed to analyze the Li storage mechanism in depth. The results support the feasibility of the new ternary sulfide Bi13S18I2 as a promising lithium ion battery.

Greigite Fe3S4 as a new anode material for high-performance sodium-ion batteries.

Project description:Transition metal dichalcogenide materials have been considered as promising anode materials for rechargeable sodium-ion batteries because of their high specific capacity and low cost. Here, we demonstrate an iron sulfide Fe3S4 as a new anode material for a rechargeable sodium-ion battery. The involved conversion mechanism has been proved when the as-prepared Fe3S4 was used as the host material for sodium storage. Remarkably, a compound FeS x with quantum size generated by conversion reaction overcame the kinetic and thermodynamic constraints of chemical conversion to achieve superior cycling and rate capability. As a result, the as-prepared Fe3S4 electrode delivers a high reversible specific capacity of 548 mA h g-1 at 0.2 A g-1, together with an excellent cycling stability of 275 mA h g-1 after 3500 cycles at 20 A g-1.

Flexible C-Mo2C fiber film with self-fused junctions as a long cyclability anode material for sodium-ion battery.

Project description:Electrospun carbon fiber films have high contact resistance at the fiber junctions, which causes poor cycling stability and limits their further improvement in energy storage performances. To eliminate the contact resistance of the film, we provide a new strategy to fuse the fiber junctions by introducing MoO2 in the fibers, which replaces the C-C interface by a more active C-MoO2-C interface at the fiber junction to promote mass transfer. MoO2 reacts with C matrix to generate Mo2C and form self-fused junctions during the carbonization process. Due to much lower charge transfer and sodium diffusion resistance, the C-Mo2C fiber film with self-fused junctions shows much better cyclability with capacity retention of 90% after 2000 cycles at a constant current density of 1 A g-1. Moreover, the Mo2C particles provide many electrochemically active sites, leading to additional improvement in sodium storage. The C-Mo2C fiber film has a capacity of 134 mA h g-1 at 1 A g-1 and a high capacity of 99 mA h g-1 even at 5 A g-1.

Carbon-Coated ZnS-FeS2 Heterostructure as an Anode Material for Lithium-Ion Battery Applications.

Project description:The construction of carbon-coated heterostructures of bimetallic sulfide is an effective technique to improve the electrochemical activity of anode materials in lithium-ion batteries. In this work, the carbon-coated heterostructured ZnS-FeS2 is prepared by a two-step hydrothermal method. The crystallinity and nature of carbon-coating are confirmed by the investigation of XRD and Raman spectroscopy techniques. The nanoparticle morphology of ZnS and plate-like morphology of FeS2 is established by TEM images. The chemical composition of heterostructure ZnS-FeS2@C is discovered by an XPS study. The CV results have disclosed the charge storage mechanism, which depends on the capacitive and diffusion process. The BET surface area (37.95 m2g-1) and lower Rct value (137 Ω) of ZnS-FeS2@C are beneficial to attain higher lithium-ion storage performance. It delivered a discharge capacity of 821 mAh g-1 in the 500th continuous cycle @ A g-1, with a coulombic efficiency of around 100%, which is higher than the ZnS-FeS2 heterostructure (512 mAh g-1). The proposed strategy can improve the electrochemical performance and stability of lithium-ion batteries, and can be helpful in finding highly effective anode materials for energy storage devices.

Diffusion mechanism in the sodium-ion battery material sodium cobaltate.

Project description:High performance batteries based on the movement of Li ions in Li x CoO2 have made possible a revolution in mobile electronic technology, from laptops to mobile phones. However, the scarcity of Li and the demand for energy storage for renewables has led to intense interest in Na-ion batteries, including structurally-related Na x CoO2. Here we have determined the diffusion mechanism for Na0.8CoO2 using diffuse x-ray scattering, quasi-elastic neutron scattering and ab-initio molecular dynamics simulations, and we find that the sodium ordering provides diffusion pathways and governs the diffusion rate. Above T ~ 290 K the so-called partially disordered stripe superstructure provides channels for quasi-1D diffusion, and melting of the sodium ordering leads to 2D superionic diffusion above T ~ 370 K. We obtain quantitative agreement between our microscopic study of the hopping mechanism and bulk self-diffusion measurements. Our approach can be applied widely to other Na- or Li-ion battery materials.

Ideal Bi-Based Hybrid Anode Material for Ultrafast Charging of Sodium-Ion Batteries at Extremely Low Temperatures.

Project description:Sodium-ion batteries have emerged as competitive substitutes for low-temperature applications due to severe capacity loss and safety concerns of lithium-ion batteries at - 20 °C or lower. However, the key capability of ultrafast charging at ultralow temperature for SIBs is rarely reported. Herein, a hybrid of Bi nanoparticles embedded in carbon nanorods is demonstrated as an ideal material to address this issue, which is synthesized via a high temperature shock method. Such a hybrid shows an unprecedented rate performance (237.9 mAh g-1 at 2 A g-1) at - 60 °C, outperforming all reported SIB anode materials. Coupled with a Na3V2(PO4)3 cathode, the energy density of the full cell can reach to 181.9 Wh kg-1 at - 40 °C. Based on this work, a novel strategy of high-rate activation is proposed to enhance performances of Bi-based materials in cryogenic conditions by creating new active sites for interfacial reaction under large current.

KxCo1.5-0.5xFe(CN)6/rGO with Dual-Active Sodium Ion Storage Site as Superior Anode for Sodium Ion Battery.

Project description:The unique and open large frame structures of prussian blue analogues (PBA) enables it for accommodating a large number of cations (Na+, K+, Ca2+, etc.), thus, PBA are considered as promising electrode materials for the rechargeable battery. However, due to the chemical composition, there are still many alkaline metal ions in the gap within the framework, which puts multivalent metals in PBA in a low valence state and affects the sodium storage performance. To improve the valence of metal ions in PBA materials, precursors prepared by co-precipitation method and hydrothermal method are used to synthesis KxCo1.5-0.5xFe(CN)6 through further chemical oxidation. Through the introducing of reduced graphene oxide (rGO) with excellent conductivity by a simple physical mixing method, the cycle stability and rate performance of the PBA material can be further improved. The K0.5Co1.2Fe(CN)6·2H2O/rGO anode prepared with 2 h hydrothermal time and further chemical oxidation, named as KCoHCP-H2-EK/rGO, exhibits a super electrochemical performance, delivering initial charge/discharge capacities of 846.7/1445.0 mAh·g-1, and a capacity retention of 58.2% after 100 cycles at a current density of 100 mA·g-1. The KCoHCP-H2-EK/rGO outstanding electrochemical behaviors are attributed to the unique dual-active site structure properties and the improved surface conductance of materials by rGO components.
