An explosion resistant structure for a lithium battery is disclosed which is composed of a top cap (10), an explosion resistant plate (22) and sealing film (24). The top cap is formed of a circular flat portion (12) and a projected portion (14) projected from the central portion of the flat portion and has a plurality of cut blades (18) which are provided at the side wall of the projected portion by cutting the top cap V-shaped and folding the cut portion inwardly. The explosion resistant plate is positioned adjacent to the cut blades but not to contact with the cut blades and has its peripheral edges fixed to expand upwardly upon rising of inner pressure of the battery. The sealing film is coated on the lower surface of the explosion resistant plate and keeps the hermetic state of the battery by fusion. |
