The present invention relates to: a non-aqueous electrolyte composition for a lithium secondary battery, comprising an anhydrosugar alcohol derivative; and a lithium secondary battery including same and, more specifically, to: a non-aqueous electrolyte composition comprising a specific amount of an anhydrosugar alcohol derivative as an additive and being capable of providing a lithium secondary battery having an improved battery lifespan property and storage stability; and a lithium secondary battery including same.

Non-aqueous electrolyte composition for lithium secondary battery having improved lifespan, and lithium secondary battery including same

The present invention relates to a polyol composition comprising anhydrosugar alcohols and an anhydrosugar alcohol polymer and, more specifically, to a polyol composition comprising a monoanhydrosugar alcohol, a dianhydrosugar alcohol, and a polymer of a monoanhydrosugar alcohol and/or a dianhydrosugar alcohol, the polyol composition being usable in various fields since the physical property conditions of the composition, such as number average molecular weight (Mn), polydispersity index (PDI) and hydroxyl value, satisfy specific levels, and, particularly, being capable of remarkably improving the physical properties of a polyurethane, such as tensile strength and elongation, when used as a polyurethane chain extender.
