Natrium. Sodium is a chemical element with the symbol Na (from Latin: natrium) in the periodic table and atomic number 11. It is a soft, silvery-white, highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature, but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 …

During the red mud segregation roasting process, sodium sulfate reacts with alumina, silica, etc. to form sodium silicate and sodium aluminosilicate, which inhibits the formation of fayalite and ...

Metallic sodium is a promising anode material due to its remarkably high theoretical capacity (1165 mA h g −1) and ... the difficulty to scale up the process for fabricating sodium metal anodes and the low melting point of sodium metal, should be further addressed. Relatively fewer studies have so far been devoted to improving the situations ...

The peak for the metallic sodium (1131 ppm) remains unchanged, but there are now four peaks observed for the sodium in the electrolyte, at chemical shifts of 1, 0, −5 and −7 ppm (Supplementary ...

Upon the completion of the charging process, the sodium metal acts as the anode material, while the g-C 3 N 4 film functions as SEI that effectively prevents direct contact between the metallic sodium and the liquid electrolyte, thereby enhancing the chemical stability and electrochemical performance of the SMA.
