摘要： A secondary battery with improved life characteristics is provided. The secondary battery (lithium-ion secondary battery) has: an electrode assembly including positive electrodes and negative electrodes; and a package container for housing the electrode assembly along with non-aqueous electrolyte liquid. The package container includes a package can for housing the electrode assembly and a sealing plate sealing the opening of the package can. On the sealing plate, an elevated portion is formed that projects toward the electrode assembly and has, on the side opposite from the electrode assembly, a cavity portion for storing refill non-aqueous electrolyte liquid. The elevated portion has a hole for feeding the refill non-aqueous electrolyte liquid stored in the cavity portion toward the electrode assembly. The hole is sealed with a sealing stopper formed of a resin material letting the refill non-aqueous electrolyte liquid leak toward the electrode assembly.

摘要： Provided are a secondary battery and a battery pack, in which when a plurality of secondary batteries having a laminated electrode assembly are stacked to constitute the battery pack, deformation of each secondary battery can be suppressed, electrode assemblies are not shifted, and no breakage occurs in terminals, even if an external force such as vibration is applied. For this purpose, a secondary battery (RB) includes anti-displacement members disposed inside and outside of the lid member (12) so as to be symmetric with respect to a surface of the lid member (12), so that secondary batteries are formed. Then, the secondary batteries are stacked and housed as a unit in a battery pack casing (CA), and a fixing means for uniformly pressing the same position in the stack direction so as to press and fix all the secondary batteries as a unit, so that a battery pack (M1) is formed.
