Electrode for lithium secondary battery

摘要

Disclosed is a method for forming an electrode having a protective layer, which includes: mixing an aliphatic nitrile compound with an electrode active material and a solvent to form slurry for electrode active material; applying the slurry for electrode active material on a collector; and removing the solvent used in the slurry by drying to form a protective layer comprising an aliphatic nitrile compound-electrode active material complex.
