Disclosed is a secondary battery using a polymer radical material and a conductivity-imparting agent, wherein the performance of a conductive auxiliary layer is further improved and the internal resistance is reduced, thereby achieving a higher output. Specifically disclosed is a secondary battery wherein at least one of the positive electrode and the negative electrode uses, as an electrode active material, a polymer radical material and a conductivity-imparting agent having electrical conductivity. By providing a conductive auxiliary layer, which is mainly composed of graphite, fibrous carbon or granular carbon having a DBP absorption of not more than 110 cm3/100g, between a collector and the polymer radical material/conductivity-imparting agent electrode, the secondary battery can have a higher output. |
