Preparation and electrochemical characterization of magnesium gel electrolytes based on crosslinked Poly(tetrahydrofuran) was written by Tominaga, Yoichi;Kato, Sawako;Nishimura, Naomi. And the article was included in Polymer in 2021.Reference of 112-49-2 This article mentions the following:
A crosslinked poly(tetrahydrofuran) (c-PTHF) was synthesized as a novel polymer matrix for gel polymer electrolyte (GPE) swelled with Mg(TFSI)2/triglyme solution to develop Mg-ion battery. Two GPE based on c-PTHF with different crosslinking structure and crosslinker ratio were obtained as free-standing membranes with excellent heat resistance. From the CV measurement, the Pt/GPE/AZ31 cell clearly showed Mg redox reaction, and the values of current densities in reduction/oxidation peaks and the Coulombic efficiency were larger than those of the triglyme electrolyte solution This may be due to the changes in the solvation structure of Mg2+ ions by the presence of crosslinking structures in the network framework. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Reference of 112-49-2).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Reference of 112-49-2
