Phosphate and phosphazene electrolyte additives for Li-ion batteries
Meet. , Volume MA2012-01, Issue 6, Pages 334.
Tris(hexafluoro-isopropyl)phosphate was first observed to extend the cycling life of a full Li-ion cell using a and a commercial graphite anode. This particular heavily fluorinated phosphate was also usedsuccessfully to allow extended (>500 cycles) useful cycling of a LiCoPO4cathode vs. lithium

PFO-EC在(EC:EMC=3:7,)溶解性较差,最大浓度为2wt%,而其他溶解度为5wt%。推测PFO-EC的分解产物在电解液中的溶解性较低,从而成膜稳定性高。
