Abstract
This application relates to an electrode plate, an electrochemical apparatus, and an apparatus thereof. The electrode plate of this application includes a current collector, an electrode active material layer provided on at least one surface of the current collector, and an electrical connection member electrically connected to the current collector. The electrode active material layer is provided on a main body portion of the current collector in a zone referred to as a film zone, the electrical connection member and the current collector are welded and connected at an edge of the current collector, at a welding zone referred to as an transfer welding zone and a transition zone is referred to as an extension zone, where the transition zone is of the current collector between the film zone and the transfer welding zone, and is coated with no electrode active material layer.
