Angell, Michael published the artcileIonic Liquid Analogs of AlCl3 with Urea Derivatives as Electrolytes for Aluminum Batteries, Category: isoquinoline, the main research area is ionic liquid aluminum chloride urea electrolyte aluminum graphite battery.
The ionic liquid analog, formed through the mixture of urea and AlCl3, has previously shown to serve as a low-cost electrolyte for an aluminum-graphite battery, while maintaining good performance and achieving high Coulombic efficiency. Undesirable are the relatively high viscosity and low conductivity of this electrolyte, when compared to chloroaluminate ionic liquids with organic cations. In this work, the fundamental changes to the electrolyte resulting from using derivatives of urea (N-Me urea and N-Et urea), again mixed with AlCl3, are examined These electrolytes are shown to have significantly lower viscosities (η = 45, 67, and 133 cP when using N-Et urea, N-Me urea, and urea, resp., at 25°). The associated batteries exhibit higher intrinsic discharge voltages (2.04 and 2.08 V for N-Me urea and N-Et urea electrolytes, resp., vs. 1.95 V for urea system@100 mA g-1 specific current for â?5 mg cm-2 loading), due to changes in concentrations of ionic species. Aluminum deposition is directly observed to primarily occur through reduction of Al2Cl7- when AlCl3 is present in excess, in contrast to previously suggested cationic Al-containing species, via operando Raman spectroscopy performed during cyclic voltammetry.
