2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.HPLC of Formula: 112-49-2
Probing the Reactivity of the Active Material of a Li-Ion Silicon Anode with Common Battery Solvents was written by Han, Binghong;Zhang, Yunya;Liao, Chen;Trask, Stephen E.;Li, Xiang;Uppuluri, Ritesh;Vaughey, John T.;Key, Baris;Dogan, Fulya. And the article was included in ACS Applied Materials & Interfaces in 2021.HPLC of Formula: 112-49-2 This article mentions the following:
Calculations and modeling have shown that replacing the traditional graphite anode with silicon can greatly improve the energy d. of lithium-ion batteries. However, the large volume change of silicon particles and high reactivity of lithiated silicon when in contact with the electrolyte lead to rapid capacity fading during charging/discharging processes. In this report, we use specific lithium silicides (LS) as model compounds to systematically study the reaction between lithiated Si and different electrolyte solvents, which provides a powerful platform to deconvolute and evaluate the degradation of various organic solvents in contact with the active lithiated Si-electrode surface after lithiation. NMR (NMR) characterization results show that a cyclic carbonate such as ethylene carbonate is chem. less stable than a linear carbonate such as ethylmethyl carbonate, fluoroethylene carbonate, and triglyme as they are found to be more stable when mixed with LS model compounds Guided by the exptl. results, two ethylene carbonate (EC)-free electrolytes are studied, and the electrochem. results show improvements with graphite-free Si electrodes relative to the traditional ethylene-carbonate-based electrolytes. More importantly, the study contributes to our understanding of the significant fundamental chem. and electrochem. stability differences between silicon and traditional graphite lithium-ion battery (LIB) anodes and suggests a focused development of electrolytes with specific chem. stability vs lithiated silicon which can passivate the surface more effectively. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2HPLC of Formula: 112-49-2).
