Beschreibung
Zusammenfassung:	Disclosed are an electrode plate and a battery having the same. The electrode plate includes a current collector, a first coating and a second coating, the first coating is coated on at least one surface of the current collector, the second coating is coated on a surface of the first coating away from the current collector, and an Ol value of the second coating is less than an Ol value of the first coating. Compared with the related art, the electrode plate of the disclosure divides a thick coating layer into the first coating and the second coating for separate coating in order to ensure an energy density of the battery, and then the Ol value of the second coating is set to be less than that of the first coating. Therefore, an entire Ol value of the electrode plate is low.
