Effect of Substrates on the Physicochemical Properties of LiLaZrO Films Obtained by Electrophoretic Deposition.

Thin film technology of lithium-ion solid electrolytes should be developed for the creation of all-solid-state power sources. Solid electrolytes of the LiLaZrO (LLZ) family are one of the promising membranes for all-solid-state batteries. LLZ films were obtained by electrophoretic deposition on Ti, Ni and steel substrates.

Recent Strategies for Lithium-Ion Conductivity Improvement in LiLaZrO Solid Electrolytes.

The development of solid electrolytes with high conductivity is one of the key factors in the creation of new power-generation sources. Lithium-ion solid electrolytes based on LiLaZrO (LLZ) with a garnet structure are in great demand for all-solid-state battery production. LiLaZrO has two structural modifications: tetragonal () and cubic ().

Electrophoretic Deposition and Characterization of Thin-Film Membranes LiLaZrO.

In the presented study, films from tetragonal LiLaZrO were obtained by electrophoretic deposition (EPD) for the first time. To obtain a continuous and homogeneous coating on Ni and Ti substrates, iodine was added to the LiLaZrO suspension. The EPD regime was developed to carry out the stable process of deposition.

Thermal Conductivity of FLiNaK in a Molten State.

Although the thermal conductivity of molten salt mixtures is of interest for many potential technological applications, precise values are often hard to obtain. In this study, the thermal diffusivity of FliNaK was studied in a molten state using the laser flash method and found to be very slightly dependent on temperature. The heat capacity of FliNaK was measured using the DSC method.

Impact of LiBO Addition on Solid Electrode-Solid Electrolyte Interface in All-Solid-State Batteries.

All-solid-state lithium-ion batteries raise the issue of high resistance at the interface between solid electrolyte and electrode materials that needs to be addressed. The article investigates the effect of a low-melting LiBO additive introduced into LiCoO- and LiTiO-based composite electrodes on the interface resistance with a LiLaZrO solid electrolyte. According to DSC analysis, interaction in the studied mixtures with LiBO begins at 768 and 725 °C for LiCoO and LiTiO, respectively.
