Functional nanolayers favor the stability of solid-electrolyte-interphase in rechargeable batteries

Rechargeable batteries have brought us lots of convenience and changed the way we live. However, the demand for higher energy density, longer cycle life, and more fast charging ability urges researchers to develop advanced battery material and chemistry[1, 2]. The solid-electrolyte-interphase (SEI) on the anodes strongly governs the rechargeable batteries' electrochemical properties, such as the coulombic efficiency, cycling stability, rate capability, and even safety.
