Silicon‐Rich Amorphous SiCx for the Lithium‐Ion Batteries: How Does Strong Carbon Doping Affect the Lithiation Behavior and Electrochemical Performance?

ChemSusChem, Volume 19, Issue 7, 14 April 2026.
In this article, amorphous substoichiometric silicon carbide (a‐SiCx), which is produced from a scalable gas‐phase process, is investigated on the influence of the carbon concentration on the electrochemical performance. Thorough testing in half‐cells combined with material analysis and postmortem studies reveals a promising material with virtually no ...
