Achieving practical, high-energy-d. calcium batteries requires controlling the stability of Ca2+ electrolytes during calcium metal cycling. Because of the highly reactive nature of calcium, most typical electrolyte constituents are unstable, leading to electrode passivation and low Coulombic efficiency. Among various com. available salts, calcium bis(trifluoromethylsulfonyl)imide (Ca(TFSI)2) is attractive because of its oxidative stability and high solubility in a variety of solvents. However, this salt does not allow for calcium metal plating, and it has been proposed that TFSI– instability induced by Ca2+ coordination is to blame. In this work, we test the ability of strongly coordinating Ca2+ cosalts such as halides and borohydrides to displace TFSI– from the first coordination shell of Ca2+ and thereby stabilize TFSI-based electrolytes to enable calcium plating. Through spectroscopic anal., we find that the effectiveness of these cosalts at displacing the TFSI– anion is dependent on the solvent’s coordination strength toward Ca2+. Surprisingly, electrochem. calcium deposition behavior is not correlated to the population of bound or free TFSI–. Instead, the nature of the coordination interaction between Ca2+ and the cosalt anion is more important for determining stability. Our findings indicate that TFSI– anions are inherently unstable during calcium deposition even in the nominally free state. Therefore, strategies aimed at eliminating the interactions of these anions with the electrode surface via interface/interphase design are required. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2SDS of cas: 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. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.SDS of cas: 112-49-2
