A secondary battery includes an electrode assembly, a case in which the electrode assembly is accommodated, the case having one opening, a sub plate assembly that includes a sub plate coupled to the electrode assembly and a current collector coupled to the...

The present disclosure relates to a secondary battery and a battery pack including the same, and a secondary battery in which a connection member is firmly welded to a terminal, and a battery pack including the same, are provided. A secondary battery inclu...

A secondary battery includes: a case; an electrode assembly inside the case; a cap assembly sealing the case and including a first terminal and a second terminal; a first tab member extending from the electrode assembly in a first direction; a first sub-pl...

Disclosed is a secondary battery and a method for manufacturing the same. The secondary battery includes an electrode assembly including a plurality of electrode plates, and a plurality of conductors joined to the electrode assembly, in which each of the p...

A secondary battery cell includes a battery cell receptacle and an electrode assembly having multiple electrodes with each of the electrodes including a cathode tab and an anode tab. The electrode assembly is at least partially enclosed within the battery ...

A secondary battery having weldability between a current collector plate and an electrode uncoated portion by increasing an absorption rate of a laser beam irradiated onto the current collector plate. The secondary battery includes an electrode assembly in...

The system has positive and negative electrodes with metallic liners. The liners have a non-coated lateral band (65) emerging from opposite sides of a bundle (63). The liners of same polarity are folded, in a direction perpendicular to their initial direct...

The device has a housing (1) containing a wound electrode arrangement (2) in which the edges of the electrodes are joined to tapping plates (41,42) by laser welding. A number of laser welding points are arranged on most of the surface of the tapping plate ...

Positive and negative electrode plates, after being dried, are layered alternately upon one another with intervening separators therebetween to constitute electrode plate groups. These electrode plate groups are transferred in succession from one to anothe...
