  "textContent": "The present application relates to the technical field of lithium battery, and provides a current collecting plate and a cylindrical lithium battery. The current collecting plate includes a circular current collecting plate, a center of the circular current collecting plate is provided with a central area, an edge of the circular current collecting plate is provided with at least one notch, and circumferences of concentric circles outside the central area of the circular current collecting plate are respectively provided with a liquid guiding hole, and each liquid guiding hole and the notch are configured for guiding liquid for to a battery electrode group at a bottom of the circular current collecting plate. The current collecting plate of the present application is provided with liquid guiding holes and at least one notch is arranged on the edge of the circular current collecting plate, so that any concentric circular electrode sheet (battery electrode group) under the current collecting plate can form a liquid injection channel, then, the liquid injection channel can be formed in any concentric circular pole piece under the current collecting plate at the first time of liquid injection of the cylindrical lithium battery, so as to obtain the penetration of the electrolyte, which can effectively improve the consistency of the electrolyte penetration of the electrode sheet, reduce the time-consuming of liquid injection, and improve the product quality.",
