“…Komaba et al have succeeded in bringing out an NIB anode of hard carbon a reversible capacity of 250-300 mA h g ¹1 by a reversible Na-insertion into its nanopores. 1 For a further high capacity, elemental phosphorous (P) 2 and tin (Sn) 3 are promising candidates of anode materials because these elements show high theoretical capacities (P, 2596 mA h g ¹1 ; Sn, 847 mA h g ¹1 ) based on alloying/dealloying reactions. Anodes consisting of elemental P or Sn, however, generally show deterioration of an active material layer and a resulting capacity decay by several ten cycles because these elements exhibit significant volume increase in their Na-storage (Na 15 Sn 4 , 525%; Na 3 P, 490%).…”

Thick-film electrodes of tin phosphides, Sn 4 P 3 and SnP 3 , were prepared using a mechanical alloying method followed by a gas-deposition method, and were evaluated as Na-ion battery anodes in an organic electrolyte and ionic liquid electrolytes. The Sn 4 P 3 electrode showed a better cycling performance in the organic electrolyte compared with the SnP 3 electrode and an Sn electrode. The performance of the Sn 4 P 3 electrode was further improved by using ionic liquid electrolytes because of a uniformly formed surface layer and resulting uniform sodiation/desodiation reactions on the electrode.

“…For example, Na can alloy with Sn and Sb to form Na 15 Sn 4 and Na 3 Sb, respectively, resulting in a theoretical capacity of 847 mAh g À 1 and 660 mAh g À 1 . Komaba et al 17 have demonstrated that Na can be alloyed with Sn with a charge capacity of about 800 mAh g À 1 , close to the theoretical capacity of Sn. However, in order to keep the stability of the material, Sn has to be cycled between 0 and 0.8 V, resulting in a reversible capacity of only 500 mAh g À 1 at a rate of 50 mA g À 1 .…”

Sodium-ion batteries are an alternative to lithium-ion batteries for large-scale applications. However, low capacity and poor rate capability of existing anodes are the main bottlenecks to future developments. Here we report a uniform coating of antimony sulphide (stibnite) on graphene, fabricated by a solution-based synthesis technique, as the anode material for sodium-ion batteries. It gives a high capacity of 730 mAh g À 1 at 50 mA g À 1 , an excellent rate capability up to 6C and a good cycle performance. The promising performance is attributed to fast sodium ion diffusion from the small nanoparticles, and good electrical transport from the intimate contact between the active material and graphene, which also provides a template for anchoring the nanoparticles. We also demonstrate a battery with the stibnite-graphene composite that is free from sodium metal, having energy density up to 80 Wh kg À 1 . The energy density could exceed that of some lithium-ion batteries with further optimization.

“…This result is in good agreement with the characteristic potential profile observed for Sn-C/Na half-cells, exhibiting different potential plateaus that indicate the formation of various intermediate-intermetallic Sn-Na alloy phases (Supplementary Figure 7). 18,19 Moreover, the preserved XRD pattern for the Sn-C electrode stored in electrolyte for 1 day indicates the absence of parasitic side reactions and confirms the successful protection of the anode from contact with seawater by the NASICON electrolyte. The Sn-C electrodes were carefully disassembled, washed by DEC, and then investigated by X-ray photoelectron spectroscopy and SEM-EDX.…”

A novel energy conversion and storage system using seawater as a cathode is proposed herein. This system is an intermediate between a battery and a fuel cell, and is accordingly referred to as a hybrid fuel cell. The circulating seawater in this opencathode system results in a continuous supply of sodium ions, which gives this system superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. Indeed, hard carbon and Sn-C nanocomposite electrodes were successfully applied as anode materials in this hybrid-seawater fuel cell, yielding highly stable cycling performance and reversible capacities exceeding 110 mAh g − 1 and 300 mAh g − 1 , respectively. NPG Asia Materials (2014) 6, e144; doi:10.1038/am.2014.106; published online 21 November 2014 INTRODUCTIONThe shift toward sustainable energy is one of the key challenges faced by the modern society and an important part of science and technology development. The performance of sustainable energy technologies must be improved to enable the more efficient utilization of intermittent-renewable electricity sources. In addition, because of the climate change, that is, global warming, because of carbon dioxide emissions, 1-3 investment is needed in renewable energy sources for electricity generation and transport. Both aims rely on the development of energy storage devices that can balance intermittent supply with consumer demands. Among the various energy conversion and storage systems, rechargeable batteries are attracting substantial attention. In particular, rechargeable lithium-ion batteries are considered a promising power source for hybrid electric vehicles and electric vehicles because of their high power and energy density. 4 However, the continuous growth of the lithium-battery market might induce a lack of resources such as lithium and cobalt. Thus, scientists from several countries have started to explore battery technologies that use alternatives to lithium, such as sodium or magnesium. 5,6 Among these alternatives, sodium possesses several advantages, such as low cost and natural abundance. In principle, the reversible storage mechanisms for sodium ions are very similar to those for lithium ions. In addition, the voltage and cycling stability of sodium-ion batteries are competitive with those of lithium-ion batteries.The same trend is indeed observed for new battery chemistries that utilize oxygen as the active cathode species; sodium has recently attracted attention as a replacement for lithium in these alkali-metalair batteries. 7-11 Such batteries are promising energy storage systems that provide very high theoretical energy densities; however, the use of pure alkali metals (both Li and Na) as anodes create safety and cost
