    摘要： Disclosed is a separator for an electrochemical device, interposed between a cathode and an anode to prevent a short circuit between both electrodes. The separator is provided with through-holes having a diameter of 1-20 μm in the thickness direction, and the surfaces of the through-holes are sealed by being coated with a thermoplastic polymer having a melting point equal to or higher than 70° C. and lower than 130° C. An electrochemical device including the separator is also disclosed. The separator can prevent rapid ignition of an electrochemical device in advance.

    摘要： Disclosed is a method for preparing a dinitrile compound. The method includes reacting an alcohol compound with a nitrile compound having a terminal carbon-carbon unsaturated bond under anhydrous conditions. A potassium alkoxide having 1 to 5 carbon atoms is used as a catalyst in the course of the reaction. According to the method, a high-purity dinitrile compound can be prepared in a simple manner within a short reaction time indicating high productivity.
