BATTERY EMPLOYING AN ELECTRODE PELLET HAVING AN INNER ELECTRODE EMBEDDED THEREIN

摘要

An electrochemical battery cell (50) comprising a cell housing (52) defining an inner space, a first terminal (56) and a second terminal (58), and at lea st one pre-formed pellet (60) disposed within the inner space of the cell housing. The pellet includes an outer electrode portion (62) formed from a material to geometrically define the pellet in a solid form. The outer electrode portion is in electrical communication with the first terminal of the cell housing. The pellet also includes an inner electrode (64) encapsulated by a separator (66) and embedded within the material of the out er electrode housing and electrically insulated from the outer electrode material. In a preferred embodiment, the inner electrode comprises an anode and the outer electrode portion comprises a cathode portion. The integrated anode/cathode pellet configuration facilitates lower costs, a more robust design and ease of manufacturability while maintaining and allowing increase d performance characteristics of the battery cell.
