Abstract
An electrode for a lithium secondary battery and a lithium secondary battery including the same, the electrode including a polyamide imide (PAI)-based binder, wherein a 1,3-benzenediamine peak is not observed when a composition including components extracted from the electrode by a solvent capable of dissolving the polyamideimide (PAI)-based binder is analyzed with pyrolysis-gas chromatography (Py-GC) under conditions of a pyrolysis temperature of about 750 to about 780° C., a pyrolysis time of about 5 seconds to about 15 seconds, and increasing a gas chromatography oven temperature from about 40° C. to about 300° C. at a rate of about 10° C./min.
