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

Résumé

Lithium-ion batteries are nowadays a mature technology for the energy storage. However, some safety problems have been identified during the operation in high power applications such as fire incident in electric vehicles. The most promising solution to improve the safety of lithium-ion batteries is replacing current organic liquid based electrolyte with solid electrolyte. In this context, new solid electrolytes having chemical and electrochemical stability with high ionic conductivity needs to be discovered. Therefore, in the present study, a new LGPS-type structure domain is highlighted for the Li-B-P-S system. The ionic conductivity of prepared solid electrolytes in the Li-B-P-S system has been achieved upto 10$^{-4}$ S/cm, and higher stability against lithium metal as compared to Li$_{10}$GeP$_2$S$_{12}$. These solid electrolytes also show better electrochemical characteristics in all solid-state batteries.
