All-solid-state lithium-sulfur battery based on a nanoconfined LiBH4 electrolyte
In this work we characterize all-solid-state lithium-sulfur batteries based on nano-confined LiBH4 in mesoporous silica as solid electrolytes. The nano-confined LiBH4 has fast ionic lithium conductivity at room temperature, 0.1 mScm-1, negligible electronic conductivity and its cationic transport number (t+ = 0.96), close to unity, demonstrates a purely cationic conductor.
The electrolyte has an excellent stability against lithium metal. The behavior of the batteries is studied by cyclic voltammetry and repeated charge/discharge cycles in galvanostatic conditions. The batteries show very good performance, delivering high capacities versus sulfur mass, typically 1220 mAhg-1 after 40 cycles at moderate temperature (55°C), 0.03 C rates and working voltage of 2 V.
