Motivated by this phenomenon, Sau et al. conducted MD (MD) study on Ba x/2 Li 1-x Ti 2 (PO 4 ) 3 , exploring compositions ranging from 0.0 < x < 0.83 to unravel the atomistic origins of enhanced cationic diffusion . Their investigations revealed that below the composition of x = 0.67, an abundance of cationic vacancies dominated, leading to a significant enhancement in cationic conduction. However, as the composition exceeded the critical value of x = 0.67, the blocking effect of cation channels became more pronounced, thereby diminishing overall cationic conduction. They also suggested a specific type of ordered arrangement of Ba atoms to avoid Li + ion channel blocking that enhances conductivity significantly. Such knowledge of Ba atom ordering and underlying mechanisms is crucial for improved conductivity within the same framework. Moreover, Duan et al. studied the influence of Ga 3+ substitution in Li 1-3x Ga x Zr 2 (PO 4 ) 3 solid-state electrolytes on their structure and ionic conductivity . Their findings indicated that Ga 3+ doping increased both the activation energy and the prefactor of ionic conductivity, with the prefactor dominating due to increased migration entropy. The study employed various techniques such as electrochemical strain microscopy, speed of sound measurements, Raman spectroscopy, and NMR spectroscopy to explore the structure-property relationships and the influence of lattice dynamics on ionic transport. The researchers suggested that optimizing both the activation energy and the prefactor is necessary to maximize the ionic conductivity of solid-state electrolytes.
