The invention relates to an electrode terminal fixing structure and a battery, a battery pack and an automobile comprising the same. A fixing structure for an electrode terminal includes: a battery case having an open end portion on one side and a bottom portion on the other side, the bottom portion having a through hole formed therein; an electrode terminal fixed to the bottom; and a terminal pad sandwiched between the electrode terminal and the bottom. The electrode terminal includes: a neck portion having a cross-section smaller than a cross-section of the through hole and inserted into the through hole; a head portion connected to one side end portion of the neck portion, having a larger cross section than a cross section of the through hole, and extending along one side surface of the bottom portion; a protruding portion connected to the other end of the neck portion and extending from the other surface of the bottom portion in the axial direction of the battery case; an expanded diameter part extending in the centrifugal direction from the protruding part; and a tip surface provided at an end portion in the axial direction of the protruding portion, the expanded diameter portion being a coupling member physically coupled to an outer peripheral surface of the protruding portion.

    本发明涉及电极端子的固定结构及包括其的电池、电池组及汽车。电极端子的固定结构包括:电池外壳,其在一侧具备开放端部,在另一侧具备形成有通孔的底部;电极端子,其固定在底部;及端子垫片,其夹在电极端子与底部之间。上述电极端子包括:颈部,其具备比通孔的截面小的截面并插入到通孔;头部,其连接到颈部的一侧端部,截面比通孔的截面大,并沿着底部的一侧表面延伸;突出部,其连接到颈部的另一侧端部,从上述底部的另一侧表面沿着上述电池外壳的轴方向延伸;扩径部,其从上述突出部向离心方向延伸;及前端面,其设置于上述突出部的轴方向上的端部,上述扩径部为物理性地结合到上述突出部的外周面的联接部件。
