Internal Buffering-Interfacial Regulation Synergy Bridges Stability and Kinetics in Microsized Silicon-Carbon Anodes.
Microsized Si/C composite anodes are promising for practical lithium-ion batteries due to their high tap density and scalability. However, their performance remains constrained by structural degradation and an unstable solid electrolyte interface (SEI), and current strategies fail to address the intrinsic coupling betw...
