The current collector comprises a strength enhancement layer (1) and a current collecting layer (2), wherein the current collecting layer (2) is stacked and bonded with the strength enhancement layer (1), and the current collecting layer (2) comprises a foam metal portion (21) and a solid metal portion (22). The solid metal portion (22) can have a supporting function, which is conducive to preventing affection to a battery due to the foam metal portion (21) being damaged by pressing when the current collector is wound into a roll.",
