Abstract: The present disclosure relate to the technical field of secondary batteries, and in particular, to a secondary battery and a top cover component thereof. The top cover component provided by the present disclosure includes a top cover plate having an electrode lead-out hole, and a second sealing portion and a second insulating portion stretching into the electrode lead-out hole, and the second sealing portion and the second insulating portion are at least partially staggered to each other on the radial direction of the electrode lead-out hole and are at least partially overlapped on the height direction. Based on this, a direct discharge clearance can be effectively blocked, and the creepage distance can be prolonged, thereby being conducive to reducing the risk of on fire or explosion and other problems of the secondary battery while withstanding a high voltage.

Abstract: A feed-through component for a conductor feed-through which passes through a part of a housing, for example a battery housing, is embedded in a glass or glass ceramic material and has at least one conductor, for example an essentially pin-shaped conductor, and a head part. The surface, in particular the cross-sectional surface, of the head part is greater than the surface, in particular the cross-sectional surface, of the conductor, for example of the essentially pin-shaped conductor. The head part is embodied such that is can be joined to an electrode-connecting component, for example an electrode-connecting part, which may be made of copper, a copper alloy CuSiC, an aluminum alloy AlSiC or aluminum, with a mechanically stable and non-detachable connection.
