1. A connection component for connecting an electrode assembly and an electrode terminal, wherein the connection component comprises:
a body, comprising a first surface and a second surface opposite to each other in a thickness direction thereof;
a convex portion, connected to the body and protruding from the first surface;
a concave portion, provided on the second surface and corresponding to the position of the convex portion; and
a gap control portion, configured to be when the connection component is stacked on another connection component, the gap control portion is in contact with the other connection component, so as to control a dimension of a gap D between the two connection components to be greater than 0.6H, wherein H is the height of the convex portion protruding from the first surface;
wherein the gap control portion comprises a first protrusion, and the first protrusion is provided on the body and protrudes from the first surface and/or the second surface, the first protrusion protrudes from the first surface and is obliquely provided towards the convex portion, or, the first protrusion protrudes from the second surface and is obliquely provided towards the concave portion.
