Abstract: A method for calculating the process capacity at a specific temperature of a lithium secondary battery includes a correction to a process capacity (Q3) at a specific temperature (T2) is performed using a value (Q1−Q2) obtained by subtracting the charge capacity (Q2) at the time of the shipping charge from the discharge capacity (Q1) measured at a discharge temperature (T1). A system for calculating a process capacity of a lithium secondary battery is provided.

Abstract: A pressure-sensitive adhesive composition, a pressure-sensitive adhesive polarizing plate and a liquid crystal display device are provided. The pressure-sensitive adhesive composition has excellent durability reliability under extreme conditions such as high temperature and/or humidity conditions, and shows superior workability such as cuttability or re-workability. Also, when the pressure-sensitive adhesive composition is applied to a polarizing plate or a liquid crystal display device, the composition can effectively prevent light leakage. Such a pressure-sensitive adhesive exhibits excellent characteristics, for example, even when the pressure-sensitive adhesive is applied to a 20-inch or more large display device.
