Current collecting plate and battery unit comprising current collecting plate

Abstract

Abstract [55] [56] The present utility model provides a current collecting plate for a battery unit, the current collecting plate comprising: a central part; and an extension part, the extension part comprising at least two blade 5 components that are spaced apart from each other in a circumferential direction around the central part, each blade component comprising: two radial extension edges; and a circumferential extension edge located between the two radial extension edges, the circumferential extension edge connecting the two radial extension edges at an outer peripheral side of the 10 blade component, wherein a slot that extends radially outward from the central part is provided between a first blade component and a second blade component that are directly adjacent, a width of the slot gradually reducing radially outward from the central part. A battery unit comprising the current collecting plate is also provided. The current collecting plate 15 of the present utility model can at least partially solve problems in the prior art such as poor welding due to thermal stress deformation of a current collecting plate during welding, and improves the reliability and welding performance of a current collecting plate.
