Effect of the boron element in a Li–P–S system

Year: 2023

Type: article

Abstract: Lithium-ion batteries are nowadays a mature system for the energy storage. However, some safety problems have been identified during the commercialization on the large scale of this technology. The most promising solution to improve the safety of lithium-ion batteries remains the use of a solid electrolyte. In this context, new solid electrolytes, chemically and electrochemically stable showing enhanced ionic conductivity has to be discovered. In this study, a new LGPS-type structure domain is highlighted for the Li-B-P-S system. The ionic conductivity of these compounds in this system reaches values of 10-4 S/cm and higher stability versus lithium than to Li10GeP2S12. These electrochemical characteristics result in better performance in all solid-state battery. However, the high reactivity of these materials versus moisture makes them very difficult to handle as solid electrolytes.
