An ultrathin ionomer interphase for high efficiency lithium anode in carbonate based electrolyte

Abstract

The authors here report an ultrathin ionomer membrane as an artificial solid-electrolyte interphase filter that minimizes parasitic reactions and enables stable dendrite-free lithium plating-stripping cycles in a carbonate-based electrolyte. The protected anodes exhibit outstanding coulombic efficiencies at room and elevated (50 °C) temperatures.
