Abstract
New highly conducting rubidium cationic solid electrolytes were synthesized on the basis of rubidium aluminates by partial substitution of Rb+ cations with Pb2+, Cd2+, and Ca2+ divalent ions and studied. All these three additives essentially increase electroconductivity of RbAlO2 especially in the low-temperature range. The values of electroconductivity and its activation energy are close for the optimum compositions in three studied systems. The conductivity of rubidium monoaluminate is increased by the studied additives due to formation of additional rubidium vacancies by substitution 2 Rb+ → Me2+ + V′Rb.
