Abstract: Provided are a current collector, an electrode plate, a battery and an application of the current collector. The current collector includes an insulation layer and a conductive layer. The insulation layer is configured to bear the conductive layer, the conductive layer is configured to bear an electrode active material layer. A room temperature film resistance RS of the conductive layer meets a conditional expression: 0.016Ω/□≤RS≤420Ω/□. By the current collector of the present application, the short circuit resistance of the battery in case of an abnormal situation causing the short circuit can be greatly increased, and the short circuit current can be greatly reduced. Thus, influence of the short circuit damage on the battery is limited to a point range, and an interrupt in the current only occurs in a point range, without disrupting normal operation of the battery in a certain period time.
