ABSTRACT:
A method of forming a button-type battery includes, a) providing a conductive first terminal housing member, a conductive second terminal housing member, an anode, and a cathode; b) providing an anode/cathode separator, the separator being pre-configured with a self-aligning shape for self-aligning receipt relative to one of the first or second terminal housing members or the cathode; c) positioning the pre-configured separator relative to the one of the first or second terminal housing members or cathode, the pre-configured separator shape facilitating final alignment of the separator relative to the one of the first or second terminal housing members or the cathode; and d) joining the first and second terminal housing members together into a sealed battery assembly, with the anode, cathode and separator being received within the sealed battery assembly. A button-type battery construction is also disclosed.
