    摘要: A method and an apparatus for electrical contacting of cells of a battery. The method includes: using a laser beam having a first beam energy to remove contamination in a region, provided for electrical contacting, of an electrically conductive outer surface of a first cell of the battery; using a laser beam having a second beam energy higher than the first, to generate at least one marking in the outer surface of the first cell, the marking having a predefined spatial relationship to the region provided for electrical contacting; and electrically contacting the first cell using a connecting apparatus, the marking being used by the connecting apparatus to localize that region of the first cell which is provided for electrical contacting in order to connect said region by way of an electrically conductive connecting element to a region, provided for electrical contacting, of a second cell of the battery.

    摘要: An electrical connector assembly disposed within an opening of an electrical device case surrounded by a sealing wall extending from an internal surface of the electrical device case may include a connector header configured to be disposed outside of the electrical device case. The assembly may include a potting material seal formed of a resilient material defining a conductor passage configured to receive and engage the electrical conductor and an outer edge configured to engage the sealing wall, thereby inhibiting a liquid potting material introduced into the electrical device case from intruding into the connector header. The assembly may include a seal retainer having an opening in which the electrical conductor is disposed and configured to retain the potting material seal within the sealing wall.

    摘要: This application provides a current collecting member, a secondary battery, and a fabrication method. The secondary battery includes an electrode assembly, a housing, a top cover assembly and current collecting members. The electrode assembly includes a main body portion and a first tab extending from an end of the main body portion along a transverse direction. The top cover assembly includes a top cover plate and a first electrode terminal disposed on the top cover plate connected to the housing. The current collecting member is connected to the first tab and the first electrode terminal. The current collecting member includes a substrate and a support plate, the substrate being provided at a side of the main body portion along a transverse direction, the support plate extending from an end part of the substrate in a longitudinal direction, and the first tab being connected to the support plate.
