Bifunctional covalent bromine: an advanced redox mediator for rechargeable lithium–oxygen batteries

Abstract

In this work, we introduce trimethylbromosilane (C3H9SiBr), which can protect lithium metal anodes via an in situ formed SEI layer while catalyzing the decomposition of Li2O2. As a result, lithium–oxygen batteries with C3H9SiBr offer a long cycle life of 110 cycles with a significantly reduced charging/discharging overpotential.
