Abstract

An embodiment of the present invention relates to a secondary battery comprising: an electrode assembly having an anode tab formed at one end thereof and a cathode tab formed at the other end thereof; a case in which the electrode assembly is received and which is open at both opposite ends thereof; and a pair of cover assemblies coupled to respective open ends of the housing. According to the present invention, the cap assembly is formed on opposite sides of the case, so that a cathode terminal and an anode terminal of the cap assembly can have the same direction as a cathode tab and an anode tab of the electrode assembly, which makes it possible to simplify the shape of a current collector and minimize the length of the current collector.

Description

technical field [0001] Embodiments of the present invention relate to a prismatic secondary battery having a bidirectional terminal. Background technique [0002] A secondary battery includes an electrode assembly having a cathode, an anode, and a separator interposed between the cathode and the anode, a case having one side opening to receive the electrode assembly and electrolyte, and a cap assembly sealing the open side of the case. [0003] In general, a cap assembly of a secondary battery includes a cathode terminal and an anode terminal electrically connected to cathodes and anodes of an electrode assembly. Any one of the cathode terminal and the anode terminal is different in direction from the electrode tab of the electrode assembly, so the shape of the current collector connecting the electrode tab and the terminal of the cap assembly is complicated and its length is increased. [0004] The above information disclosed in this Background section is only for enhancem...
