| 摘要 |
The present invention relates to widening a welding area where an uncoated region contacts a current collecting plate of a rechargeable battery and preventing a laser beam from penetrating through an electrode assembly during manufacture. The rechargeable battery includes an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, a case for housing the electrode assembly, a cap plate connected to the case, a connecting member formed between uncoated regions of the electrode assembly by interposing an insert metal injected in the molten state and then hardened, a current collecting plate welded to the reinforcing member, and an electrode terminal connected to the current collecting plate and penetrating the cap plate. |
