摘要：
New potassium-conducting solid electrolytes based on potassium monogallate in the K2−2xGa2−xVxO4 system are synthesized and studied. It is found that an introduction of V5+ ions leads to a considerable increase in the KGaO2 conductivity due to the formation of vacancies in the potassium sublattice. The conductivity for optimal compositions is approximately 10−3 S cm−1 at 400°C and above 10−2 S cm−1 at 700°C. The results are compared with early obtained data for potassium monogallate dopped with four-charged cations.
