Estimating the term…
The present disclosure provides a current collector, an electrode plate and a battery. The current collector includes an insulation layer and at least one conductive layer located on at least one surface of the insulation layer. The insulation layer is used to support the conductive layer, and the conductive layer is used to support an electrode active material layer. The conductive layer has a thickness of D2, and 300 nmD22 μm. The current collector further includes a protective layer provided on a surface of the conductive layer facing towards the insulation layer. The current collector according to the present disclosure can increase a short-circuit resistance in case of short circuit caused by the battery being abnormal, thereby resulting in protective effect on the conductive layer, and can also increase the bonding force between the insulation layer and the conductive layer, thereby increasing mechanical strength of the current collector.
A current collector, comprising
An electrode plate, comprising a current collector and an electrode active material layer formed on the current collector,
A battery, comprising a positive electrode plate, a separator, and a negative electrode plate, wherein the positive electrode plate and/or the negative electrode plate is an electrode plate,
