Title: A self-forming composite electrolyte for solid-state sodium battery with ultra-long cycle life

Abstract

Replacing organic liquid electrolyte with inorganic solid electrolytes (SE) can potentially address the inherent safety problems in conventional rechargeable batteries. Furthermore, all-solid-state batteries have been plagues by the relatively low ionic conductivity of solid electrolytes and large charge-transfer resistance resulted from solid-solid interfaces between electrode materials and solid electrolytes. Here we report a new design strategy for improving the ionic conductivity of solid electrolyte by self-forming a composite material. An optimized Na + ion conducting composite electrolyte derived from the NASICON structure was successfully synthesized, yielding ultra-high ionic conductivity of 3.4 mS cm –1 at 25°C and 14 ms cm –1 at 80°C.

  • Alkali metal-oxygen batteries are of great interests for energy storage because of their unparalleled theoretical energy densities. Particularly attractive is the emerging Na-O 2 battery because of the formation of superoxide as the discharge product. Dimethyl sulfoxide (DMSO) is a promising solvent for this battery but its instability towards Na makes it impractical in the Na-O 2 battery. Here in this paper, we report the enhanced stability of Na in DMSO solutions containing concentrated sodium trifluoromethanesulfonimide (NaTFSI) salts (>3molkg -1). Raman spectra of NaTFSI/DMSO electrolytes and abinitio molecular dynamics simulation reveal the Na + solvation number in DMSO and themore » formation of Na(DMSO) 3(TFSI)-like solvation structure. The majority of DMSO molecules solvating Na + in concentrated solutions reduces the available free DMSO molecules that can react with Na and renders the TFSI anion decomposition, which protects Na from reacting with the electrolyte. Using these concentrated electrolytes, Na-O 2 batteries can be cycled forming sodium superoxide (NaO 2) as the sole discharge product with improved long cycle life, highlighting the beneficial role of concentrated electrolytes for Na-based batteries.« less
  • In situ high energy X-ray diffraction (HEXRD) and in situ X-ray absorption near edge spectroscopy (XANES) were carried out to understand the soild state synthesis of Na xMnO 2, with particular interest on the synthesis of P2 type Na 2/3MnO 2. It was found that there were multi intermediate phases formed before NaMnO 2 appeared at about 600 °C. And the final product after cooling process is a combination of O'3 NaMnO 2 with P2 Na 2/3MnO 2. A P2 type Na 2/3MnO 2 was synthesized at reduced temperature (600 °C). The influence of Na 2CO 3 impurity on themore » electrochemical performance of P2 Na 2/3MnO 2 was thoroughly investigated in our work. It was found that the content of Na 2CO 3 can be reduced by optimizing Na 2CO 3/MnCO 3 ratio during the solid state reaction or other post treatment such as washing with water. Lastly, we expected our results could provide a good guide for future development of high performance cathode materials for sodium-ion batteries.« less
  • Experimental work was directed toward determining the viability of two complementary solid-state electrochemical cells incorporating Na/sup +/ and Li/sup +/ conducting solid polymer electrolytes (SPE). SPEs used included those based upon poly(ethylene oxide), poly(ethylene oxide)/poly(ethylene glycol) mixtures, and polyphosphazenes. For Li/sup +/ conducting SPEs, LixWO/sub 2/ was used for the negative and TiS/sub 2/ for the positive electrode. In cells utilizing Na+ conducting SPEs, homogeneous matrix electrodes based upon transition-metal-doped B'-alumina were used for the positive and negative electrodes. Here transition metals were incorporated into immobile A1/sup 3 +/ lattice sites within the B'-alumina structure, where changed in electrochemical potentialmore » upon cell charge/discharge cycling occurred via redox electrochemistry involving the doped immobile transition-metal species. Secondary cells were found to have respective open-circuit potentials of 2.2 and 1.5V, high electrochemical reversibility, and theoretical energy densities of 175 and 178 Wh/kg.« less
