Abstract
A secondary battery is provided, comprising a first adapter piece and an electrode assembly, comprising a first and second electrode plates, a plurality of first electrode tabs, a second electrode tab, a direction parallel to the first electrode plate being L, two end points in a thickness direction being Tand T, a position of one of the first electrode tabs farthest from Tor Tis T; all the first electrode tabs are stacked to form a first multi-tab structure and connected to the first adapter piece, it further comprises a first adapter member comprising the first multi-tab structure and the first adapter piece; in the L direction, there is at most one layer of the first adapter member. The present application may reduce the existing waste of the top space caused by bending electrode tabs, and is more stable for the bending effect, improving the ED of battery.
