Current collector, secondary battery and electronic device

Abstract

An embodiment of the present disclosure provides a current collector, configured to electrically connect an electrode assembly and a terminal, and including: a terminal fixing part and an electrode assembly connecting part disposed around the terminal fixing part; and a first transition part, connected between the terminal fixing part and the electrode assembly connecting part. The current collector has an electrode assembly connecting side and a terminal connecting side distributed in opposite directions. The first transition part and the terminal fixing part respectively include a first surface and a first end surface located on the terminal connecting side, as well as a second surface and a second end surface located on the electrode assembly connecting side. The second surface protrudes in a direction away from the terminal connecting side compared with the second end surface.

Dependencies are inferred from the claim text.
