A button-type battery has an anode, a cathode, and an electrolyte encased with two terminal housing members. The terminal housing members have respective peripheries that are crimped together to form a fluid-tight seal. An insulating gasket is provided between the peripheries to electrically insulate the two terminal housing members. A porous separator physically separates the anode and cathode and extends between the terminal housing member peripheries at least partially into the fluid-tight seal. According to one aspect, the separator overlaps the gasket in the seal. According to another aspect, the separator and gasket are formed of a single, integral piece of material.

Methods of producing button-type batteries and a plurality of battery

A button-type battery has an anode, a cathode, a separator, and an electrolyte encased within a housing and surrounding by a fluid-tight peripheral seal. The battery is capable of being deflected such that a first portion of the battery is angled relative to a second portion through an internal angle between the first and second portions in a range from 175.degree. to at least 90.degree. without destroying operation of the button-type battery or rupturing the fluid-tight peripheral seal.
