Resumen de: US2025192242A1
A lithium-ion battery cell is provided along with a process for its preparation. The method involves first saturating the cell's anode, cathode, and separator with a carbonate-based electrolyte to form a lithium fluoride-rich passivation layer. Subsequently, this electrolyte is flushed and replaced by a soft solvents-based electrolyte. This two-step electrolyte process may help form a more robust initial passivation layer.
