Electrolyte without FEC is composed primarily of poly (VC), polycarbonates and lithium carbonate. Incorporation of10%wt FEC results with the formation of poly (VC/FEC), polycarbonates, lithium carbonate species, alkoxy species and aflcyl phosphates. Incorporation of FEC also result with the increase in the formation of poly (VC/FEC). Moreover in the course of d discharging, incorporation of FEC impedes the decomposition of both solvent and salt anion reduction. ? The Electrochemical Society. |
