Structural and Chemical Evolution of Silicon and the Solid-Electrolyte Interphase (SEI) Layer

Structural and Chemical Evolution of Silicon and the Solid-Electrolyte Interphase (SEI) Layer

Cryo-STEM imagery showing the structural and chemical evolution of silicon and the solid-electrolyte interphase (SEI) layer. After the 36th cycle to the 100th cycle the silicon nanowire expands and becomes irregular, mingling with the SEI to form a soft composite structure.
