Influence of the structure of the anion in an ionic liquid electrolyte on the electrochemical performance of a silicon negative electrode for a lithium-ion battery
Anode property of silicon was affected by anion structure of ionic liquid electrolyte for LIB. Si electrode exhibited good cyclability with capacity of 2000 mA h g−1 in FSA-based electrolyte. High rate performance was achieved in FSA-based electrolyte. Conductivity of FSA-based electrolyte was three times higher than that of TFSA-based one.
