Abstract
The manuscript investigates the synthesis and characterization of Aluminum alloys, comprising Si, Ti and B as alloying elements, as anodes for Al-ion batteries. Deposition/stripping measurements, impedance spectroscopy, metallographic, energy dispersive X-ray spectroscopy (EDXS) and X-ray diffraction (XRD) techniques unveil the complex interplay existing between the microstructures of the alloys and the obtained electrochemical performance. Prototype cycling and post-mortem battery failure analysis are performed as well. It is demonstrated that a remarkable improvement in the: a) oxidation/reduction currents and overvoltages; and b) interfacial stability with the electrolyte; can be obtained, with respect to a conventional Al anode.
