Excellent cycling stability of sodium anode enabled by a stable solid electrolyte interphase formed in ether-based electrolytes

Sodium (Na)-ion batteries have been considered as one of the most promising power sources beyond Li-ion batteries. Although Na metal anode exhibits a high theoretical capacity of 1165 mAh g-1, its application on Na batteries is largely hindered by dendrite growth and low Coulombic efficiency. Herein, we demonstrate that an electrolyte consists of 1 M sodium tetrafluoroborate in Tetraglyme can enable excellent cycling efficiency (99.9 %) of Na metal anode for more than 1000 cycles. This high reversibility of Na anode can be attributed to a stable solid electrolyte interphase formed on Na surface as revealed by cryogenic transmission electron microscopy and X-ray photoelectron spectroscopy. These electrolytes also enabled excellent cycling stability of Na||hard carbon cells and Na||Na2/3Co1/3Mn2/3O2 cells at high rate with very high coulombic efficiencies.

How far can sodium substitute for potassium in red beet?

Sodium (Na) movement between plants and humans is one of the more critical aspects of bioregenerative systems of life support, which NASA is studying for the establishment of long-term bases on the Lunar or Martian surface. This study was conducted to determine the extent to which Na can replace potassium (K) in red beet (Beta vulgaris L. ssp vulgaris) without adversely affecting metabolic functions such as water relations, photosynthetic rates, and thus growth. Two cultivars, Ruby Queen and Klein Bol, were grown for 42 days at 1200 micromoles mol-1 CO2 in a growth chamber using a re-circulating nutrient film technique with 0%, 75%, 95%, and 98% Na substitution for K in a modified half-strength Hoagland solution. Total biomass of Ruby Queen was greatest at 95% Na substitution and equal at 0% and 98% Na substitution. For Klein Bol, there was a 75% reduction in total biomass at 98% Na substitution. Nearly 95% of the total plant K was replaced with Na at 98% Na substitution in both cultivars. Potassium concentrations in leaves decreased from 120 g kg-1 dwt in 0% Na substitution to 3.5 g kg-1 dwt at 98% Na substitution. Leaf chlorophyll concentration, photosynthetic rate, and osmotic potential were not affected in either cultivar by Na substitution for K. Leaf glycinebetaine levels were doubled at 75% Na substitution in Klein Bol, but decreased at higher levels of Na substitution. For Ruby Queen, glycinebetaine levels in leaf increased with the first increase of Na levels and were maintained at the higher Na levels. These results indicate that in some cultivars of red beet, 95% of the normal tissue K can be replaced by Na without a reduction in growth.
