Abstract
The present application relates to a current collector, an electrode plate, a battery and usages thereof. The current collector includes at least one conductive layer configured to support an electrode active material layer, and an insulation layer configured to support the at least one conductive layer. The conductive layer has a room temperature film resistance Rsatisfying 0.01Ω/□≤R≤0.15Ω/□. The current collector can significantly increase resistance in short-circuit and reduce current in the short-circuit, and reduce heat generated during the short-circuit and improving safety performance. The heat can be totally absorbed by the battery. Therefore, the resulted temperature rise of the battery is small, the damage to the battery caused by the short circuit can be limited to a 'point', and only a 'point break' is formed, without influencing normal operation of the battery in a short time.
