Abstract

A secondary battery (500) and an electronic device (400) are provided. The secondary battery (500) includes a housing (600), an electrode assembly (700), and a current-collecting plate (902). The housing (600) includes an end wall configured with an explosion-proof valve (904). The electrode assembly (700) is accommodated within the housing (600), with a tab (716) extending from an end of the electrode assembly (700) facing the explosion-proof valve (904). The current-collecting plate (902) is welded to the tab (716) and includes a first opening (102) passing through the center thereof and multiple second openings (104). The first opening (102) extends in a radial direction of the current-collecting plate (902). The second openings (104) are distributed on both sides of the first opening (102). A portion between end portions of the second openings (104) close to the first opening (102) and the first opening (102) constitutes a tearable portion (108).
