“…Although the doping of single elements improves the ionic conductivity of LLZO to varying degrees, multiple studies have shown that synergistic codoping (Y/Ta, Al/Si, Sb/Ba, Al/Te, Ta/Ca, and Nb/Y) at different sites contributes to a more significant enhancement in ionic conductivity. To further reveal the synergistic mechanism of codoped LLZO, this paper reports the use of Al and Nb dopants to research the synergistic codoping modification of LLZO.…”

“…Several studies, both experimental and theoretical, have already investigated some of the effects of doping on LLZO. Three types of doping can be identified: (i) the substitution of Li ions by hypervalent cations such as Al [18,19] or Ga [20], (ii ) the substitution of the metal centers by cations such as Ce [21], Ta [22,23], W [24,25] and Nb [15], and (iii ) a co-doping by more than one of the two first options [26][27][28][29].…”

“…Although formation of Li vacancy could improve the Li ion conductivity, there should be an optimum Li vacancy content, where total conductivity should reach maximum . Further increase of Li vacancy will decrease the content of mobile Li ion and deteriorate the conductivity . In present study, the maximum conductivity has been obtained at x =0.2.…”
