Trimethylsilyl azide (C3H9N3Si): a highly efficient additive for tailoring fluoroethylene carbonate (FEC) based electrolytes for Li-metal batteries

The addition of trimethylsilyl azide (C₃H₉N₃Si) to FEC-based electrolytes enhances Li-metal stability and thus it enables the outstanding cycling stability of Li-metal battery at a practical level.
