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.

摘要： A battery pack 1 of the present invention includes: a plurality of lithium ion secondary batteries 10 electrically connected together in series, in parallel, or in series-parallel combination; a tray 11; and a housing 12. The lithium ion secondary batteries 10 each include an electrode assembly containing an alloy-based negative electrode active material serving as a negative electrode active material, and each have a sealed surface 10a. The lithium ion secondary battery 10 is mounted on the tray. The housing 12 accommodates the tray 11 with the lithium ion secondary battery 10 mounted thereon. Even if high-temperature contents are produced in the interior of the lithium ion secondary battery 10 in the event of internal short circuiting or overcharging, this configuration prevents the high-temperature contents from leaking out of the batter pack 1, and thus improves the safety of the battery pack 1.

摘要： In a secondary battery (1) comprising a battery case (2) for accommodating an electrode plate group (3) and an electrolyte, with one open end of the battery case (2) being sealed with an assembled sealing plate (11) that accommodates a safety mechanism (17) for exhausting pressure in the event of pressure build-up in the battery case (2) exceeding a predetermined level, at least one part (13a) of vent holes (13a, 13b, 13c) in the assembled sealing plate (11) facing the inside of the battery case (2) is constituted of an aperture that results from formation of a turned-out portion (23), the distal end of the turned-out portion (23) being allowed to abut on an insulating plate (4a) that makes contact with one end of the electrode plate group (3) so as to restrict movement of the electrode plate group (3). This can prevent malfunctioning due to displacement of the electrode plate group (3) when an impact or vibration is applied.
