Abstract

To provide an aerogel composition having improved thermal insulation, fire resistance, mechanical properties, and / or dustiness, a method for preparing the aerogel composition, a battery insulation sheet formed using the aerogel composition, and a method for preparing the battery insulation sheet.SOLUTION: The present invention relates to an aerogel composition for battery insulation sheets that includes a reinforcement material including two or more fibrous supports, an aerogel, a functional material including a binder, a dispersant, or a combination thereof, and a solvent, wherein the two or more fibrous supports have different aspect ratios (AR) as represented by Formula 1: AR=L / D, where in Formula 1, L indicates an average length of the fibrous supports and D indicates an average diameter of the fibrous supports. The present invention also relates to a method for preparing the aerogel composition, a battery insulation sheet formed using the aerogel composition, and a method for preparing the battery insulation sheet.SELECTED DRAWING: Figure 1
