摘要： Disclosed herein is a non-aqueous solvent secondary battery, which has excellent long-term reliability and high thermal-resistance through the improved thermal resistance of the collectors. The non-aqueous solvent secondary battery comprises a cathode electrically coupled to a collector, an anode electrically coupled to a collector and an electrolyte layer interposed between the cathode and anode. The cathode, anode and electrolyte layer are stacked upon one another. The collector of the cathode side comprises an alloy-based metal foil with at least a portion of the collector of the cathode side having a Pitting Resistance Equivalent (PRE) of 45 or more.
