A rechargeable battery includes: an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and the second electrode; a case configured to accommodate the electrode assembly and having an opening; a cap plate configured to be combined to the opening; a first current collecting member and a second current collecting member configured to be electrically connected to the first electrode and the second electrode, respectively; and a first terminal and a second terminal configured to be electrically connected to the first electrode and the second electrode, respectively, and the first current collecting member may include a first current collecting plate electrically connected to the first electrode, and a first connecting protrusion which protrudes from the first current collecting plate and has a first terminal hole into which the first terminal is inserted.

Rechargeable battery

A rechargeable battery includes an electrode assembly, a case accommodating the electrode assembly, a cap plate coupled to the case, an electrode terminal within a terminal hole of the cap plate, and a lead tab connecting the electrode assembly to the electrode terminal, wherein the electrode terminal includes a plate terminal located outside of the cap plate and having a through-hole corresponding to the terminal hole, a sub-terminal extending into the through-hole and coupled to the plate terminal, and a rivet terminal penetrating the terminal hole, the rivet terminal being connected to the lead tab and being compression-molded to the sub-terminal.

Rechargeable battery comprising sub-terminal and rivet-terminal structure

A rechargeable battery includes: an electrode assembly including a first electrode and a second electrode, a case configured to receive the electrode assembly, a first current collecting member including a first fuse unit coupled to the first electrode and having a cross-sectional area that is smaller than a cross-sectional area of a periphery of the first current collecting member, and a second current collecting member including a second fuse unit coupled to the second electrode and having a cross-sectional area that is smaller than a cross-sectional area of a periphery of the second current collecting member, in which the first fuse unit is configured to melt more quickly than the second fuse unit at a first current, and the second fuse unit is configured to melt more quickly than the first fuse unit at a second current that is lower than the first current.

Rechargeable battery having fuse unit

A rechargeable battery including an electrode assembly, a case housing the electrode assembly, a cap plate coupled to the case, a first electrode terminal on the cap plate, and a first lead tab electrically connecting the electrode assembly and the first electrode terminal, wherein the first lead tab has a cell fuse and a heat dissipating member coupled to the first lead tab and spaced from the cell fuse.

A rechargeable battery including an electrode assembly that performs a charge and discharge operation; a case that houses the electrode assembly; a cap plate coupled to an opening of the case; an electrode terminal installed in the cap plate; and a lead tab that connects the electrode assembly to the electrode terminal, wherein the lead tab includes a current collecting connection portion that is connected to the electrode assembly; a terminal connection portion that is bent from the current collecting connection portion to be connected to the electrode terminal; and an injection material that embeds the terminal connection portion in which a fuse is formed, and wherein the injection material includes an exposing hole therein, the exposing hole exposing at least one side of the fuse.
