Magnesium rechargeable batteries are candidates for post-lithium-ion batteries owing to the low price and superior theor. volume energy d. of Mg anodes. As a promising cathode material, MgMn2O4 spinel has a high energy d. with a high operating voltage, and a relatively high ionic conductivity However, the tetragonal symmetry of MgMn2O4, originating from the Jahn-Teller effect of Mn3+ ions, causes irreversible structural changes during the charge/discharge process, leading to poor reversibility. We developed metastable cubic MgMn2O4 spinel nanoparticles using the hot-injection method under low-temperature solvothermal conditions. Compared to tetragonal MgMn2O4, its cubic phase exhibited a superior reversible capacity, both exptl. and theor., at room temperature In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Formula: C8H18O4).
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. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Formula: C8H18O4
