METHOD OF CONNECTING ELECTRODE OF STORAGE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method of welding the electricity collection plate and the electrodes preventing the welding heat from adversely affecting the other parts to enhance the reliability. SOLUTION: The edge of the sheet-like electrode 51 is contacted with the electrode collection plate 54 substantially at right angle. The two corner regions 51e around the region of the collection plate 54 contacting the electrode 51 are filled with a shield material 64 against laser or electron beam, and then the contact region 51c is subjected to a laser or electron beam from the other side of the collection plate 54 opposite thereto.
