Abstract
The paper reports a study of the effect of the partial substitution of silicon or titanium cations for germanium ions on the resistivity and activation energy for conduction of Li6.25Ge1.75Al(Ga)0.25O7 solid el ectrolytes. The results give ample reason to state that, given a const ant crystal structure and a constant charge-carrier concentration, the electric conductivity of the solid solutions in question is determine d by the geometric factor. The covalence of the rigid lattice, which h as a direct bearing on the strength of the bond between the mobile lit hium cations and oxygen anions, plays an insignificant role.
