Understanding the Nature of Solid‐Electrolyte Interphase on Lithium Metal in Liquid Electrolytes: A Review on Growth, Properties, and Application‐Related Challenges

A stable solid-electrolyte interphase (SEI) is of crucial essence for realization lithium (Li) metal batteries. This article provides an overview attempts undertaken to understand the nature natural SEI, including growth behavior at open circuit potential and under cycling conditions as well underlying causes instabilities. Additionally, influence features such morphology composition SEI electrolyte properties on charge transport transfer mechanism, resulting in distinct overall stability, elaborated. Finally, it will be discussed how already fundamental stage research, take into account implications that progressing from coin-cell level more realistic cell has stability.
