摘要：

Hexamethylene diisocyanate can chemically react with the onium ion produced by the oxidation of propylene carbonate and in situ generate a novel interfacial layer that is stable at high potential. With an appropriate thickness of this film, LiNi1/3Co1/3Mn1/3O2 presents significantly improved rate and cycle performances when tested between 2.5 and 4.6 V (vs. Li/Li+).
