Metal anodes and protected interfaces: general discussion.

This document is a discussion from the journal Faraday Discussions on the topic of metal anodes and protected interfaces in lithium-oxygen batteries. The participants discuss various aspects of battery performance, including the use of lithium peroxide in the anode, the stability of materials against water and carbon dioxide, the deposition of lithium on copper electrodes, and the impact of depth of discharge and current density. They also discuss the fabrication of pinhole-free LLZO membranes and the use of ceramic electrolytes. The researchers have made observations on metal ion migration, short circuit formation, and the compatibility of LLZO with different liquid electrolytes. They have disclosed their conflicts of interest. [Extracted from the article]
