摘要： A secondary battery is provided that can be built into an assembled battery at lower cost than by building a secondary battery employing a laminate film into an assembled battery and that permits easy stacking. The secondary battery has: an electrode assembly including a positive electrode and a negative electrode; a package container including a package can in which the electrode assembly is housed and a lid member which seals an opening of the package can all around its circumference; and electrolyte liquid directly filling the housing container The outer bottom face of the housing container and the outer top face of the lid member are shaped such that one substantially fits into the other.

摘要： Provided is a reliable secondary battery with improved life characteristics. The lithium-ion secondary battery (secondary battery) has: a positive electrode which includes a positive electrode active material layer; a negative electrode which includes a negative electrode active material layer and which is arranged to face the positive electrode; a housing container in which the positive and negative electrodes are housed; and a lid member which seals the opening of the housing container. The positive and negative electrodes have edge portions respectively, and are housed in the housing container with a pressing force applied to a region of the positive and negative electrode active material layers excluding at least part of the edge portions.
