Rechargeable battery having a current distribution member
First Claim
1. A rechargeable battery, comprising:
- an electrode assembly consisting of a first electrode, a separator, and a second electrode;
a case accommodating the electrode assembly;
a cap assembly coupled with the case, the cap assembly including a terminal;
a first current collecting member, the first current collecting member including;
a fuse portion connecting the terminal with the first electrode, andan electrode bonding portion fixed to the electrode assembly, the fuse portion having a lower melting point than other portions of the first current collecting member;
a current distribution member fixed to the first current collecting member, the current distribution member electrically connecting the first current collecting member with the case; and
a safety member that is electrically connected to the second electrode, the safety member being between the electrode assembly and the case,wherein the current distribution member is fixed to the first current collecting member at a connecting path that is between the fuse portion and the electrode assembly such that the current distribution member forms a current path from the connecting path to the case,wherein the cap assembly includes;
a cap plate coupled with the case, anda connecting member that electrically connects the terminal with the cap plate, andwherein the safety member includes a safety member side plate that faces a flat side surface of the electrode assembly, a surface of the safety member side plate that faces the electrode assembly including an insulating film thereon,wherein the current distribution member includes;
a current collecting member-fixing portion that is fixed to the first current collecting member, anda case fixing portion that is fixed to the case,wherein the case fixing portion is fixed to a bottom inner side of the case such that the case fixing portion is electrically connected to the bottom inner side of the case,wherein the bottom inner side of the case faces the electrode assembly, andwherein the case fixing portion is directly adjacent to the electrode assembly.
