摘要： A non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery including the same are provided. The non-aqueous electrolyte solution includes an organic solvent, an ionizable lithium salt, a dinitrile compound including an ether bond represented by Chemical Formula 1, and an aliphatic dinitrile compound represented by Chemical Formula 2. The lithium secondary battery including the non-aqueous electrolyte solution having the possibility of generating a swelling phenomenon while storing or charging/discharging at a high temperature may be restrained. In addition, a cycle life of the charging/discharging may be improved.

摘要： A transmittance-variable film and the use thereof are provided. The transmittance-variable film can be useful in switching between a clear state and a dark state and reducing a difference in contrast ratio between left and right viewing angles, thereby securing excellent bilateral symmetry. Such a transmittance-variable film can be applied to various applications including various materials for buildings or vehicles requiring the control of transmissivity, or eyewear such as goggles for sports or experiencing augmented realities, sunglasses, helmets, etc.
