Abstract: Provided are a pressure relief structure, comprising a carrier substrate, the carrier substrate having a pressure relief portion and a remaining area other than the pressure relief portion, with the thickness of the pressure relief portion being smaller than that of the remaining area. The ratio of the thickness of the pressure relief portion to the length of the carrier substrate in a first direction is denoted as A, where A is greater than 5.6×10−6 and less than 0.028, and/or the ratio of the thickness of the pressure relief portion to the width of the carrier substrate in a second direction is denoted as B, where B is greater than 5×10−5 and less than 0.1. The first direction, the second direction and a thickness direction of the pressure relief portion intersect with each other.

Abstract: A battery includes a cylindrical battery cell having a cylindrical side surface provided with a pressure relief mechanism, an electrical chamber configured to accommodate the battery cell, a collection chamber configured to collect emissions from the battery cell when the pressure relief mechanism is actuated, and an isolation component configured to isolate the electrical chamber from the collection chamber. The isolation component includes a first region and a second region. The first region is used for accommodating a first portion of the battery cell such that the first portion protrudes, towards the collection chamber, from a surface of the second region facing towards the collection chamber, and the pressure relief mechanism is disposed in a region of the cylindrical side surface located in the first portion such that the emissions are allowed to enter the collection chamber when the pressure relief mechanism is actuated.
