Open Access Publication of the Month – Asmaa Loutati (IEK-1) et al.
12 January 2023
To encourage us all to broaden our horizons, each month the Central Library selects one open access publication from the JuSER publications portal to be featured in the newsletter of Forschungszentrum Jülich.
In the open access publication of the month, Asmaa Loutati, Prof. Olivier Guillon, Dr. Frank Tietz, and Prof. Dina Fattakhova-Rohlfing (all IEK-1) write about the production and characterization of new lithium solid-state ion conductors in which the phosphate groups in the crystal lattice were successively replaced by silicate groups.
Ion conductors with a NaSICON structure have been around for a long time and their conductivity has been optimized many times by substituting cations. However, these compounds have a low electrochemical stability in solid-state batteries when lithium metal is used as the anode. The aim of the investigations was therefore to improve the electrochemical stability by selecting suitable cations and simultaneously to lower the processing temperature by altering the anion lattice, about which little is currently known. Substituting the phosphate groups with silicate groups effectively reduces the sintering temperature, but the ionic conductivity does not meet the requirements for use in solid-state batteries.
Die Open-Access-Publikation mit dem Titel "NaSICON-type solid-state Li+ ion conductors with partial polyanionic substitution of phosphate with silicate" wurde in der Zeitschrift "Open ceramics" veröffentlicht.

Zur Auswahl von Kationen wurde zuvor der Artikel "Survey of Zirconium‐Containing NaSICON‐type Solid‐State Li+ Ion Conductors with the Aim of Increasing Reduction Stability by Partial Cation Substitution" in der Zeitschrift "Batteries & supercaps" veröffentlicht.
