Abstract
In this work, we introduce trimethylbromosilane (CHSiBr), which can protect lithium metal anodes an formed SEI layer while catalyzing the decomposition of LiO. As a result, lithium-oxygen batteries with CHSiBr offer a long cycle life of 110 cycles with a significantly reduced charging/discharging overpotential.
摘要
在这项工作中，我们引入了三甲基溴化硅（CHSiBr），它可以保护锂金属阳极和形成的 SEI 层，同时催化 LiO 的分解。结果，含有 CHSiBr 的锂-氧电池具有 110 次循环的长循环寿命，并且充电/放电过电势显著降低。
