Anode interfacial layer formation via reductive ethyl detaching of organic iodide in lithium–oxygen batteries

To fulfill the great promise of Li-O2 batteries, the high charge overpotential is a major challenge that has to be addressed. Here the authors introduce triethylsulfonium iodide as a redox mediator as well as an enabler of a protective layer on Li anode, leading to notable electrochemical performanc...

Sumario:To fulfill the great promise of Li-O2 batteries, the high charge overpotential is a major challenge that has to be addressed. Here the authors introduce triethylsulfonium iodide as a redox mediator as well as an enabler of a protective layer on Li anode, leading to notable electrochemical performance.
