Chemistry for Sustainable Development 20 (2012) 6976 Ion Conductors with the Conductivity over Lithium Ions and Solid Electrochemical Devices Based on Them

Abstract A review of works aimed at the development of solid electrochemical devices based on lithium systems is presented. The criteria for the choice of solid electrolyte are described, a brief review of the properties of known solid electrolytes under in solid lithium batteries and rechargeable batteries are described. Special attention is paid to the properties of composite solid electrolytes. Examples of known solid primary and secondary lithium current sources differing in design and type of solid electrolyte are presented. It is shown that the composite solid electrolytes (ceramic, polymer ceramic and glass ceramic) are most suitable for use in solid lithium rechargeable batteries. A brief review of the works aimed at the development of solid supercapacitors is given. The data on solid supercapacitors with solid electrolyte based on lithium perchlorate and carbon electrode materials are presented

Temperature-programmed C18O2 SSITKA for powders of fast oxide-ion conductors: Estimation of oxygen self-diffusion coefficients

For powders of oxide-ion conductors based on Al/Fe- doped lanthanum silicates as well as Sc+Ce-doped zirconia, the temperature –programmed exchange with C18O2 in the SSITKA mode was applied for estimation of the oxygen self-diffusion coefficients Do. Comparison with results obtained for dense ceramics of these electrolytes using SIMS isotope profiling and conductivity measurements demonstrated a reasonable agreement for powders sintered at high temperatures, thus providing required verification of C18O2 SSITKA approach. For powders calcined at moderate temperatures much lower values of DO were obtained thus suggesting a strong negative effect of inhomogeneity of dopants spatial distribution on the oxygen mobility
