(57) [Abstract] [Purpose] In a lithium secondary battery that is repeatedly charged and discharged, prevents deterioration of adhesion between the current collector and the electrode layer, and has a large capacity and repeated charging and discharging even when the current density is increased. It is an object of the present invention to provide an electrode in which the capacity is less likely to decrease when it is turned on. In a secondary battery provided with a non-aqueous electrolytic solution containing a lithium-containing electrolyte, an electrode layer constituting a negative electrode and / or a positive electrode contains carbon black and a polymer compound curable by irradiation with radiation, and A lithium secondary battery, which is formed on a current collector via a base layer that has been subjected to radiation curing treatment. |
