5 results about "Methylenedioxy" patented technology

Methylenedioxy is the term used in the field of chemistry, particularly in organic chemistry, for a functional group with the structural formula R-O-CH₂-O-R' which is connected to the rest of a molecule by two chemical bonds. The methylenedioxy group consists of two oxygen atoms connected to a methylene bridge (-CH₂- unit). The methylenedioxy group is generally found attached to an aromatic structure such as phenyl where it forms the methylenedioxyphenyl or benzodioxole functional group which is widely found in natural products, including safrole, and drugs and chemicals such as tadalafil, MDMA, paroxetine and piperonyl butoxide.

Ether-based electrolyte for improving high-voltage and long-period operation stability of sodium ion battery and preparation method and application thereof

This invention provides an ether-based electrolyte for improving the high-voltage and long-cycle stability of sodium-ion batteries, its preparation method, and its application. The ether-based electrolyte comprises a base electrolyte and additives; the additives include aromatic isocyanates and alkoxysilanes. The aromatic isocyanates are a combination of one of the following: 6-fluoro-1H-1,3-benzodioxane-8-yl isocyanate, 3,4-dihydro-1,5-benzodioxane-7-isocyanate, or 3,4-(methylenedioxy)phenyl isocyanate, and 4-trifluoromethoxyphenyl isocyanate; the alkoxysilanes are 2-cyanoethyltriethoxysilane or 3,3,3-trifluoropropyltriethoxysilane. The electrolyte of this invention achieves synergistic regulation of interfacial reactions and interfacial film evolution, is suitable for sodium-ion half-cells or full-cells, and can improve overall stability and operating efficiency under high-voltage and long-cycle operating conditions.
