Abstract

The cover shows cyclic fluorinated phosphazene compounds as additional stabilizing additives in a state-of-the-art electrolyte for SiOx/C-based lithium ion battery cells. In article number 2203503 Aurora Gomez-Martin, Tobias Placke, and co-workers demonstrate the beneficial properties of these compounds in terms of gassing, electrolyte stabilizing, electrochemical performance and solid electrolyte interphase forming ability by considering realistic and practical testing conditions.
