ELECTROLYTE COMPOSITION AND ALUMINUM BATTERY CONTAINING THE SAME

An electrolyte composition including an aluminum salt, an ionic liquid, and a phthalocyanine coordination compound is provided. The anion of the aluminum salt is F-, Cl-, Br-, I-, BF4-, PF6-, [(CF3SO2)2N]-, CF3SO3-, NO3-, CH3CO2-, SO42-, C2O42-, or [B(C2O4)2]-. The ionic liquid has a structure as shown in formula (I) in the specification. The phthalocyanine coordination compound contains a divalent metal ion. In the electrolyte composition, the weight of the aluminum salt is greater than that of the ionic liquid, and the weight of the ionic liquid is greater than that of the phthalocyanine coordination compound. An aluminum battery (100) containing the electrolyte composition (20) is also provided.
