Abstract
A current collector comprises a current collector body, provided with a first side and a second side which are oppositely arranged, an opening passing through the first side and the second side being formed in the current collector body; and a blocking structure, which is arranged at the opening and is used for preventing solid particles from passing through the opening from the first side to move to the second side. The blocking structure facilitates an electrolyte to enter, via the current collector, a space above or below the current collector inside a casing, thus ensuring that the electrolyte wets an end of an electrode assembly and increasing the internal space utilization of the casing, and additionally, the blocking structure can prevent metal particles generated during a welding process of the current collector from entering the electrode assembly.
