A method of forming a button-type lithium electrode includes: a) masking an electrically conductive sheet with a material to which elemental lithium will not appreciably adhere to define a masked portion and an unmasked portion, the unmasked portion being in the shape of the desired electrode being formed; c) applying molten lithium to the masked sheet to cause elemental lithium to adhere to the unmasked portion but not appreciably adhere to the masked portion; alternately, directing a lithium stream onto the sheet; d) solidifying the lithium on the unmasked portion to in situ form a lithium electrode; and e) after solidifying, removing the masking material from the masked portion of the sheet. An alternate method includes: a) providing a release liner sheet having elemental lithium adhered thereto in the form of a series of discrete patterns having a size and shape of the lithium electrodes being formed; b) providing an electrically conductive sheet having an exposed surface which is divisible into a plurality of areas; c) laminating the release liner sheet with the conductive sheet to adhere the series of discrete elemental lithium patterns onto the respective sheet areas; d) pulling the release liner sheet from the conductive sheet and discrete lithium patterns, leaving the discrete lithium patterns adhering to the conductive sheet; and e) cutting and forming a plurality of discrete battery terminal housing members from the areas of the sheet, with each of the discrete battery terminal housings bearing one of the discrete lithium patterns.
