To evaluate the potential of Na-ion batteries, we contrast in this work the difference between Na-ion and Li-ion based intercalation chemistries in terms of three key battery properties -voltage, phase stability and diffusion barriers. The compounds investigated comprise the layered AMO 2 and AMS 2 structures, the olivine and maricite AMPO 4 structures, and the NA-SICON A 3 V 2 (PO 4 ) 3 structures. The calculated Na voltages for the compounds investigated are 0.18-0.57 V lower than that of the corresponding Li voltages, in agreement with previous experimental data. We believe the observed lower voltages for Na compounds are predominantly a cathodic effect related to the much smaller energy gain from inserting Na into the host structure compared to inserting Li. We also found a relatively strong dependence of battery properties with structural features. In general, the difference between the Na and Li voltage of the same compound, ∆V Na-Li , is less negative for the maricite structures preferred by Na, and * To whom correspondence should be addressed 1 more negative for the olivine structures preferred by Li. The layered compounds have the most negative ∆V Na-Li . In terms of phase stability, we found that open structures, such as the layered and NASICON structures that are better able to accommodate the larger Na + ion generally have both Na and Li versions of the same compound. For the close-packed AMPO 4 structures, our results show that Na generally prefers the maricite structure, while Li prefers the olivine structure, in agreement with previous experimental work. We also found surprising evidence that the barriers for Na + migration can potentially be lower than that for Li + migration in the layered structures. Overall, our findings indicate that Na-ion systems can be competitive with Li-ion systems.

The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for nextgeneration battery development. However, there are a number of challenging technical hurdles that must be addressed for LiAir batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg.

“…Ever since Goodenough, Hong & Kafalas (1976) reported high sodium-ion mobility in NASICON, Nal+xZr2P3-xSixO12, alkali silicates have been the subject of continued investigations of their ion transport properties. We were especially interested in preparing and characterizing the compound Na3NdSi6Ol5 as we had previously measured the conductivity of K3NdSi6Ol5 (Haile, Wuensch, Siegrist & Laudise, 1992) and found it to have a reasonably high conductivity for a material in which K ÷ is the mobile species.…”

Hydrothermal investigations of the high silica region of the Na20-Nd203-SiO2 system, carried out in the search for new fast-ion conductors (FIC's), yielded the compound Na3NdSi6Ols.2H20 (sodium neodymium silicate). Single-crystal X-ray methods provided lattice constants of a=7.385(2), b=30.831(7) and c= 7.1168 (13) /~,, space group Cmm2, and 22 atoms in the asymmetric unit. With four formula units per unit cell, the calculated density is 2.68gcm -3. Refinement was carried out with 1113 independent structure factors to a weighted residual wR(F) of 2.63% [8.09% for wR(F2)] using anisotropic temperature factors for all atoms. The structure, based on corrugated Si6015 layers containing four-, five-, six-and eightmembered rings, is related to that of a model previously reported for a compound assigned the composition NaNdSi6013(OH)2.nH20. Our structure differs in the placement of sodium ions and water molecules, and contains no hydroxyl groups. We believe that both studies examined the same phase.
