Nonflammable Fluorinated Carbonate Electrolyte with High Salt-to-Solvent Ratios Enables Stable Silicon-Based Anode for Next-Generation Lithium-Ion Batteries

and a low capacity fading rate (only 0.064% per cycle) after 300 cycles are delivered. The performance enhancement mechanism is further explored by electrochemical impedance spectroscopy, Fourier transform infrared, and scanning electron microscopy. This study may shed an inspiring light on the development of next-generation high-energy-density batteries.
