Improving the Cycling Stability of SiO2 Anodes for Li‐ion Batteries by Controlling Solid Electrolyte Interphase Chemistry and Structure

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
Electrolyte engineering improves the cycling stability of SiO2 anodes. LiFSI forms thinner, inorganic‐rich SEI layers than LiPF6. FEC and VC create poly(VC)‐enriched SEI films. Combined electrochemical and spectroscopic analysis reveal SEI structrue‐performance interplay. Abstract Silicon‐based negative electrodes are essential for next‐generation high‐

Simultaneous modulation of oxygen and carbon compositions in SiOC ceramics for high‐capacity and durable anode materials

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract Phenyl‐rich silicone (Si) oil is successfully cured through the protodesilylation reaction using sulfuric acid, and its subsequent inert pyrolysis significantly improved the yield of the SiOC ceramics. By varying the amount of sulfuric acid during the reaction, the carbon and oxygen compositions in the resulting SiOC ceramics were effectively ...
