To provide a secondary battery which can suppress the rise of the battery temperature owing to the chemical reaction in overcharging, and can suppress a remarkable breakdown such as bursting or exprosion of the battery.

A positive electrode active material layer 2 is formed by mixing LiCoO2 powder, graphite powder, and PVD (polyvinyliden fluoride), sufficiently at the weight ratio 80:10:10, adding the N-methyl-2-pyridone to be a dispersion solvent in an adequate amount there, and mixing sufficiently, and dispersing them to make into an ink form. Furthermore, a specific amount of lithium nitride is added there, and mixed and dispersed again. The resultant mixture is applied on both surfaces of a positive electrode aggregate 1 by the roll-to-roll transcription, and dried, so as to obtain the positive electrode active material layer 2. By using such positive electrodes, an organic electrolyte secondary battery is manufactured.
