Abstract
A non-aqueous electrolyte secondary battery (large size cell) that has high output (low resistance) and high capacity makes it possible to improve the cycle characteristics of a battery by controlling the balance of the resistance between positive and negative electrodes. The non-aqueous electrolyte secondary battery has a positive electrode which comprises an active material and a conductive aid, a negative electrode, and an electrolyte layer, and having battery capacity of 3 Ah or more and an absolute value of battery internal resistance of 30 mΩ or less, in which the non-aqueous electrolyte second battery is characterized in that the zeta (ζ) potential between the active material and the conductive aid is in the range of 0.3 mV to 2 mV as an absolute value.
