Description

X-ray absorption spectroscopy (XAS) were employed for the investigations on the local structure and oxidation state of Lithium Aluminum Borate Glasses($L{i}_{2}O$-$A{l}_2$$O_3$ -$B_2$$O_3$) doped with various concentrations of xNi:Co (where x = 1, 2, 3, and 4).XAS analyses revealed that all glasses comprise the mixed oxidation state of Ni${}^{+2}$ and Ni${}^{+3}$ corresponding to cyclic voltammetry (CV) results measured. TEM diffraction pattern and XRD patterns were used to confirm phase structure of all samples. Interestingly, electrochemical properties of prepared ($L{i}_{2}O$-$A{l}_2$$O_3$ -$B_2$$O_3$) glasses could be enhanced by changing the Ni/Co ratio in glass structure.
