Cell and battery

Abstract

The present invention discloses a cell and a battery, wherein the cell comprises a body including a first electrode tab; and a choke that triggers after the temperature reaches a certain value to reduce the current passing through it; the choke is electrically connected to the first electrode tab, and a product of the length of connection path from the choke to the first electrode tab and a cooling coefficient of the connection path is smaller than a difference between a first temperature of the first electrode tab and a second temperature of the choke, wherein the second temperature of the choke is a temperature when the choke is triggered. In the above-mentioned cell, if the trigger action of the choke is timely, the body of the cell can be prevented from reaching the overcharge state, and the choke in the above-mentioned cell can further effectively protect the cell.
