Solid Electrolyte Membranes Based on LiO-AlO-GeO-SiO-PO Glasses for All-Solid State Batteries.

Rechargeable Li-metal/Li-ion all-solid-state batteries due to their high safety levels and high energy densities are in great demand for different applications ranging from portable electronic devices to energy storage systems, especially for the production of electric vehicles. The LiAlGe(PO) (LAGP) solid electrolyte remains highly attractive because of its high ionic conductivity at room temperature, and thermal stability and chemical compatibility with electrode materials. The possibility of LAGP production by the glass-ceramic method makes it possible to achieve higher total lithium-ion conductivity and a compact microstructure of the electrolyte membrane compared to the ceramic one.

Physico-Chemical Properties of NaVO Prepared by Solid-State Reaction.

Sodium-vanadium oxide NaVO is synthesized via solid-state method and optimum synthesis conditions are chosen based on the data of DSC and TG analysis. The material synthesized is characterized by X-ray phase analysis, Raman spectroscopy and scanning electron microscopy. The ratio V/V in the sample obtained is determined by X-ray photoelectron spectroscopy.
