摘要： A secondary battery (100) having weldability between a current collector plate (120, 130) and an electrode-uncoated portion (111a, 112a) by increasing an absorption rate of a laser beam irradiated onto the current collector plate (120, 130). The secondary battery (100) includes an electrode assembly (110) including a first electrode plate (111) having a first electrode-uncoated portion (111a) protruding to one side, a second electrode plate (112) having a second electrode-uncoated portion (112a) protruding to an opposite side, and a separator (113) between the first and second electrode plates (111, 112); a case (160) accommodating the electrode assembly (110) and having a bottom surface (161) and long and short side surfaces (162, 163) extending upward from the bottom surface (161); and a first current collector plate (120, 120') having a flat portion, parallel to a short side surface (163), that is laser-welded to the first electrode-uncoated portion (111a), and a protrusion portion protruding from the flat portion toward the short side surface (163). A surface treatment part is on the flat portion.

摘要： A battery cell (12), suitable for use in an electric vehicle, comprises a prismatic conductive casing (13) having an electrically conductive casing body (14) with a width (W), a height (H) and a thickness (T) and having a generally rectangular cross-section when seen in the thickness direction (z).
A stack (16,16') of layer assemblies is accommodated in the casing body, each layer assembly comprising a cathode layer, an anode layer and a separator layer there between, the layers extending in a width direction (x) and in a height direction (y) and being of a generally rectangular shape, a stack height extending in the thickness direction (z).
The cathode and anode layers each comprise a cathode tab and an anode tab, respectively, one set of tabs (18,18') extending in the width direction (x) along a lower part (19), substantially along the width (W) of the casing (13) and being in conductive contact with a bottom (20) of the casing (13).
A conductive cover (15) is attached to the casing body (14) and defines a top plane (37) of the battery cell (12), a first terminal (25) being situated at or near the top plane, conductively connected to the cover (15).
The other set of tabs (22,51,51') extend in the width direction (x) along a section of an upper part (23) of the layer stack and is connected to a conductor (48,52,53) that projects through an opening in the cover (15) via an insulator member (17,38,43,44,55).
