"interphase protective layer lets lithium metal have as many cycles as lithium-ion... increased presence of components known making interphase more protective. but XRD data shows lithium fluoride was missing, although it is generally regarded as necessary component of good interphase, but lithium fluoride-free interphase enabled long cycle life and fast charging... lithium formed by electrochemical reactions deposits uniformly when cesium nitrate added to electrolyte, stabilizing electrode"
