Button cell

Abstract

A button cell includes a packaging member and an electrode assembly. The packaging member includes an insulating wall, a first end cover, and a second end cover. The insulating wall is provided with a through accommodating cavity, and the first end cover and the second end cover are arranged at two ends of the accommodating cavity, respectively. The insulating wall is further provided with a first communication hole for communication between the accommodating cavity and an external environment of the packaging member. The electrode assembly is accommodated in the accommodating cavity and includes a first electrode plate and a second electrode. The packaging member further includes a first conductive terminal arranged at the first communication hole, which is electrically connected to the first electrode plate forming an outer tab of the button cell, and is arranged on a wall instead of an end cover.
