Abstract: Disclosed are a battery terminal (110), a battery cover plate assembly (100), a battery (10) and a battery pack. The battery terminal comprises: outer terminal segment (111) made of a first conductive material; an inner terminal segment (112) made of a second conductive material different from the first conductive material and having an upper end connected to a lower end of the outer terminal segment (111) so as to form a connection portion between the upper end of the inner terminal segment (112) and the lower end of the outer terminal segment (111); and a protection member (113) around the connection portion. With the battery terminal (110) according to an embodiment of the present invention, adjacent batteries can be connected together more reliably.

Abstract: A current fuse device and a battery assembly comprising the same. The current fuse device (100, 200) comprises an insulating box(1) having a cavity(10), a first conductor(21) with a first inner end(211), a second conductor(22) with a second inner end(221) and at least one elastic member(31,32) provided on at least one of the first conductor(21) and the second conductor(22) inside the cavity(10). The elastic member(31,32) forms electrical connection with the first and second inner ends(211, 221) simultaneously. The elastic member(31,32) may have elastic potential energy to break the electrical connection during short-circuiting.
