Thermochemical Crosstalk in Si‐C Anodes: Mechanism and Stabilization via a Polymerizable Phosphorus‐Based Additive (Adv. Energy Mater. 6/2026)

Si-C Anodes In this underwater-themed visualization, a TPP molecule is suspended above the electrode surface, symbolizing its participation in interfacial reactions. The red clustered spheres represent silicon domains within the Si/C anode, whose large volume fluctuations typically trigger severe side reactions. Above them lies a smooth, blue protective layer depicting the TPP-derived SEI film. By forming a denser, more inorganic-rich interphase, TPP effectively mitigate silicon expansion, suppresses uncontrolled reduction reactions, and enhances interfacial stability.
