Title: Square sealed battery
Inventor: HOSHINO KOICHI
IPC: H01M2/30
Filed: 1993-12-22
Abstract: PURPOSE:To provide a square sealed battery having stable operation pressure of a safety valve and high reliability in a seal welding part by protecting the safety valve incorporated in a cap when a sealing body is welded to an outer jacket can and exiting reliable seal welding. CONSTITUTION:A sealing body 3 is fit to an opening end 1c of an outer jacket can 1 and laser-welded. When welded, the side surface 10d, facing to the long side 1a of the can 1, of a cathode cap 10 is blocked. A safety valve incorporated is not affected by heat of welding. Although a hole 10c of the cathode cap 10 is opened toward a short side surface 1b of the can 10, since the distance to the hole 10c of the cap 10 is far from the opening end of the short side surface 1b, radiation heat, reflected heat, and melting heat of a combustible material such as a gasket 5 in the vicinity of the welding part do not enter the cathode cap 10 from the hole 10, and the safety valve is protected. Since gas containing soot is not produced from the safety valve, laser beams are not blocked, and the sealing body 3 is surely welded to the whole circumference of the can 1.
