Abstract
The formation of Li dendrites at the Li/electrolyte interface at practically relevant current densities (> 1 mA cm−2) is a critical issue hindering the deployment of non-flammable and non-toxic Li7La3Zr2O12 (LLZO) electrolyte in solid-state batteries. In this comment, the authors argue for an agreement to standardize measurements of the critical current density at which Li dendrites begin to penetrate the LLZO solid-state electrolyte.
