چکیده انگلیسی
The performance at 300 °C of Li2.9Nb0.9M0.lO4, M = W or Mo, as a solid electrolyte is compared to that reported in 2004 by McLaren et al. for Li2.9Ni0.05NbO4. The Li+ conductivity and activation energy were found to be nearly identical for M = W. Ni in the Li array does not impede Li+ mobility more than aliovalent substitution for Nb, and W(VI) is not reduced before Nb(V). Substitution of Nb(V) by Mo(VI) was not as advantageous.

► Performance of Li2.9Nb0.9M0.lO4, M = W or Mo, as a solid electrolyte is presented.
► Li2.9Nb0.9W0.lO4 showed almost same Li+-ion conductivity compared to Li2.9Ni0.05NbO4.
► W(VI) or Mo(VI) is stable in Li2.9Nb0.9M0.lO4 and not reduced before Nb(V).
