High-capacity antimony sulphide nanoparticle-decorated graphene composite as anode for sodium-ion batteries

Sodium‐ion batteries (SIBs) have been considered as the most promising candidate for large‐scale energy storage system owing to the economic efficiency resulting from abundant sodium resources, superior safety, and similar chemical properties to the commercial lithium‐ion battery. Despite the long period of academic research, how to realize sodium‐ion battery commercialization for market applications is still a great challenge. Thus, from the perspective of future practical application, this review will identify the factors that are restricting commercialization, and evaluate the existing active materials and sodium‐ion‐based full‐cell system. The design and development trends that are needed for SIBs to meet the requirements of practical applications in large‐scale energy storage will also be discussed in detail.

“…Co-intercalation between graphite and diglymebased electrolyte could also achieve a relatively high capacity of B90 mA h g À 1 and long cycle life 15 . Recent findings have shown that the anode materials for SIBs based on alloy-type (for example, metallic and intermetallic materials [16][17][18][19] ) and conversion-type (for example, sulfides [20][21][22][23] ) exhibited high initial capacity, but suffered from poor cyclability most likely due to the large volume change and the sluggish kinetics. In addition, organic anode materials (for example, Na 2 C 8 H 4 O 4 ) and carboxylate-based materials have been investigated as anode materials for SIBs 24,25 , but the electronic conductivity and cyclability still remain the significant challenge.…”

Sodium-ion batteries are emerging as a highly promising technology for large-scale energy storage applications. However, it remains a significant challenge to develop an anode with superior long-term cycling stability and high-rate capability. Here we demonstrate that the Na þ intercalation pseudocapacitance in TiO 2 /graphene nanocomposites enables high-rate capability and long cycle life in a sodium-ion battery. This hybrid electrode exhibits a specific capacity of above 90 mA h g -1 at 12,000 mA g -1 (B36 C). The capacity is highly reversible for more than 4,000 cycles, the longest demonstrated cyclability to date. First-principle calculations demonstrate that the intimate integration of graphene with TiO 2 reduces the diffusion energy barrier, thus enhancing the Na þ intercalation pseudocapacitive process. The Na-ion intercalation pseudocapacitance enabled by tailor-deigned nanostructures represents a promising strategy for developing electrode materials with high power density and long cycle life.

The lithiation and delithiation of PbS was studied. Below 1.0 V vs. Li/Li + , lithiation produced a series of Li-Pb alloys and Li 2 S. The Li-Pb alloys were reversibly lithiated and delithiated, but at a 1 C rate their capacity faded through 100 cycles. Above 1.5 V vs. Li/Li + , Li 2 S is electrooxidized to Li + and soluble polysulfides, and the sulfide is irreversibly depleted. © The Author(s) 2015. Published by ECS.

Published March 31, 2015 Presently, 86% of lead consumed in the U.S. is used in conventional automotive lead-acid batteries.1 However, hybrid and electric vehicles do not use these conventional lead-acid batteries, and so as these alternative vehicles are more widely adopted, an excess lead production capacity is likely to develop. Because lead forms a series of lithium alloys, the excess lead could be diverted for use in a different type of battery chemistry such as lithium-ion batteries. 15 Our previous study of PbTe nanoparticles showed that the combination of Li-Pb alloys and Li 2 Te formed during the first lithiation cycled stably at relatively high rates. For example, we were able to attain a capacity of 500 mAh g −1 at a C/5 rate and 300 mAh g −1 at a 10 C rate with PbTe. 16Past studies have found that GeS 17 and SnS 18 exhibit improved cycling performance over their base-metal and oxide counterparts. Here we probe whether PbS confers similar benefits over Pb and PbO and conclude that it does not. ExperimentalSynthesis and characterization.-All chemicals were purchased from Sigma-Aldrich, unless otherwise noted, and used as received. Based on a procedure by Zhang et al., PbS nanoparticles were prepared as follows.19 10 mmol of elemental sulfur was added to 100 mL of deionized water with magnetic stirring. 0.2 mol of NaOH was added in order to dissolve the sulfur. The solution was heated to ∼80• C to facilitate dissolution of the sulfur. The solution was dark yellow, but still transparent. A second solution was created by dissolving 10.2 mmol of Pb(Ac) 2 •3H 2 O in 10 ml of DI water. The first solution was allowed to cool to room temperature, and the second solution was added all at once. A black precipitate appeared immediately. The resultant PbS particles were collected by centrifugation and washed twice with DI water and once with acetone. They were then dried under vacuum at 70• C overnight. X-Ray Diffraction (XRD) measurements were performed on a Spider R-axis diffractometer with a Cu Kα radiation source at 40 kV and 40 mA. Scanning Electron Microscopy (SEM) micrographs were obtained using a Hitachi S-5500 electron microscope.Electrochemical measurements.-A slurry of PbS nanoparticles (60 wt%), p...
