英文摘要	allyl cyanide (ac) was investigated as a film-forming additive in propylene carbonate (pc)-based electrolytes for graphite anode in lithium-ion batteries. the film-forming behavior of ac was characterized with cyclic voltammetry, electrochemical impedance spectroscopy, scanning electron microscopy, and fourier transform infrared spectroscopy. by adding 2 wt% ac in the electrolyte of 1 m lipf6-pc/dmc (1:1, in vol), the exfoliation of graphite anode was effectively suppressed over cycling. graphite/li half-cell showed an initial coulombic efficiency of 75 % and a specific capacity of 300 mah/g after 48 cycles. a possible reductive polymerization mechanism of ac on the surface of graphite was proposed.
