Abstract
A semi-solid-state electrolyte system for use in a battery cell is provided. The semi-solid-state electrolyte system includes an oxysulfide solid-state electrolyte and a secondary electrolyte including a solvate ionic liquid. The semi-solid-state electrolyte system is configured for providing excellent ionic conductivity, supporting high current densities at a low stack pressure, and including excellent chemical stability. The oxysulfide solid-state electrolyte and the solvate ionic liquid are collectively configured for facilitating ion transfer between an anode of the battery cell and a cathode of the battery cell.
