Influence of dopants on the conductivity: a) changes of lattice parameter as well as ionic conductivity of bulk Li_{0.33+ x} La_{0.56− x} Sr _x TiO₃ after A‐site substitution of Sr (data from ^{[159 ]}), b) changes of ionic conductivity of rf‐sputtered Li_{0.33+ x} La_{0.56− x} Sr _x TiO₃ (data from ^{[161 ]}), c) changes of bulk and grain boundary ionic conductivity at different concentration of Al³⁺, (data from ^{[168 ]}), d) influence of B‐site substitution on the lattice parameters and ionic conductivities of Li_0.24La_0.587Ti_{1‐ x} Sn _x O₃ and Li_{0.24‐ x} La_0.587Ti_{1‐ x} Ta _x O₃ (data from^{[ 162 ]}), e) conductivity of La_{(2/3) − x} Li_3x ⊡_{(1/3) − 2x} TiO₃ at different Li⁺ concentration and processing temperatures (data from ¹⁶⁶ , ¹⁶⁷ , ^{168 ]}), and f) conductivity of Li_0.5La_0.5TiO₄ thin‐film electrolytes deposited by PLD at various temperatures (data from ¹⁶⁶ , ^{171 ]} and^{[ 172 ]} where PLD was used, and ^{[176 ]} where melt‐quench was used.)
