Isocyanate compounds as electrolyte additives for lithium-ion batteries

Korepp C, Kern W, Lanzer EA, Raimann PR, Besenhard JO, Yang MH, Moller KC, Shieh DT, Winter M

Several isocyanate compounds have been investigated with regard to their performance as film forming electrolyte additives in propylene carbonate (PC) and EC/EMC-based electrolytes. In situ and ex situ analytical methods were applied to understand the differences in performance. Particular attention was paid to the differences of aromatic and linear isocyanate compounds.
