Abstract
Official abstract text for this publication.
Disclosed is a non-aqueous electrolyte solution for a lithium secondary battery. The non-aqueous electrolyte solution includes a lithium salt, an organic solvent and additives. The additives include: 1 to 10% by weight of a mixture of a particular halogenated cyclic carbonate and a compound containing a vinylene or vinyl group; and 0.1 to 9% by weight of a nitrile compound having a C 2 -C 12 alkoxyalkyl group. A lithium secondary battery including the non-aqueous electrolyte solution is also disclosed. The lithium secondary battery is protected from catching fire when overcharged and is prevented from swelling during storage at high temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-aqueous electrolyte solution for a lithium secondary battery comprising an ionizable lithium salt, an organic solvent and additives wherein the additives comprise (a) 1 to 10% by weight of a mixture of a halogenated cyclic carbonate represented by Formula 1: wherein X and Y are each independently hydrogen, chlorine or fluorine, with the pro…
