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

In this work, we introduce trimethylbromosilane (C 3 H 9 SiBr), which can protect lithium metal anodes via an in situ formed SEI layer while catalyzing the decomposition of Li 2 O 2 . As a result, lithium-oxygen batteries with C 3 H 9 SiBr offer a long cycle life of 110 cycles with a significantly r...

Description
Summary:In this work, we introduce trimethylbromosilane (C 3 H 9 SiBr), which can protect lithium metal anodes via an in situ formed SEI layer while catalyzing the decomposition of Li 2 O 2 . As a result, lithium-oxygen batteries with C 3 H 9 SiBr offer a long cycle life of 110 cycles with a significantly reduced charging/discharging overpotential. In this work, we introduce trimethylbromosilane (C 3 H 9 SiBr), which can protect lithium metal anodes via an in situ formed SEI layer while catalyzing the decomposition of Li 2 O 2 .
