Highly Stable Li/Li3BO3–Li2SO4 Interface and Application to Bulk-Type All-Solid-State Lithium Metal Batteries
Source abstract
Abstract
All-solid-state batteries (ASSBs) are potentially safe energy storage devices. The 90Li3BO3·10Li2SO4 (mol %) glass-ceramic is one of the promising oxide electrolytes due to its high ductility and ionic conductivity. Utilization of Li metal negative electrode enhances the energy density of ASSBs. Herein, the high electrochemical stability of the 90Li3BO3·10Li2SO4 electrolyte against Li metal negative electrode was demonstrated. The symmetric cells using a dense electrolyte body with relative density of 99% synthesized by the hot-pressing technique showed excellent cycle performance for the Li dissolution and deposition reactions. Finally, the all-solid-state (Li/80LiNi0.5Mn0.3Co0.2O2·20Li2SO4) full cell operated as a secondary battery at 100 °C.
