Protection of lithium metal surfaces using tetraethoxysilane

Protection of lithium metal surfaces using tetraethoxysilane

We report the formation of an electrochemically stable protective film for lithium electrodes by reacting lithium with tetraethoxysilane. Li/Li cell tests show that coated electrodes exhibit stable plating and stripping of Li at 1 mA/cm2 for 100 cycles without any change in cell impedance.
