摘要： A button battery according to the invention comprises a first component (1) in the form of a cup-shaped container, an electrode assembly (4) inserted in the container, and furthermore a lid-shaped second component (10) fixed along its outer edge to the upper rim of the sidewall (3) of the container. Either the first or the second component comprises three portions: an electrically conductive central portion (11), an electrically conductive peripheral portion (12) and an electrically insulating intermediate portion (13) that separates and insulates the central portion from the peripheral portion. The sidewall (3) of the first component and the edge of the second component (10) are shaped so as to comprise complementary conical portions (22, 25) which are in mutual contact in the assembled battery. Said complementary conical portions enable the self-alignment of the lid (10) to the rim of the sidewall (3) during assembly of the battery, and further aid in maintaining the lid onto the container during the sealing process which may be a process of welding the lid to the container along a common perimeter. According to preferred embodiments, the edge of the lid (10) and the rim of the sidewall (3) are further provided with step portions (23, 25) configured to define a stop for the insertion of one conical portion into the other.
