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.
