摘要： A lithium secondary battery is equipped with a non-recovering safety valve comprising a valve, which ruptures when the valve opens, and a valve surrounding part that surrounds the valve. The safety valve is further disposed in the valve surrounding part, and has an anti-scattering means that prevents shards, which are produced by the valve rupturing when the valve opens, from scattering outside the battery. The anti-scattering means constitutes an anti-fragmentation part of a form that prevents shards from fragmenting from the valve surrounding part.

摘要： A battery is provided with a lid member that closes a case, a collector terminal member having an insert-through part, an insulator that electrically insulates the lid member and the collector terminal member, and a gasket that provides a seal between the lid member and the collector terminal member. The lid member has a protrusion protruding downward in the vertical direction from the bottom. A gasket is in the same position as the protruding section in an inside-outside direction, which is perpendicular to the vertical direction, and has a sealing part pressed by the protruding section. At least one gap exists in the vicinity of the seal section in a different position to the seal section in the inside-outside direction, and at least portions of the gaps are enclosed by the gasket and the collector terminal member.

摘要： A secondary battery includes a cylindrical battery case, a positive and negative electrode body group, a top plate and a battery lid connected to first and second electrode bodies of the electrode body group respectively. The secondary battery further includes a current collector placed on an end of the electrode body group on the top plate side and connected to the first electrode body of the electrode body group and a spacer placed between the top plate and the current collector. The top plate is partly formed with a thin portion. The spacer is formed with through holes in positions corresponding to the thin portion. The portion of the current collector corresponding to the thin portion is in contact with the thin portion through the through hole. The thin portion is deformed when the internal pressure of the battery case rises, thereby breaking electric connection between the top plate and the current collector.
