摘要： The purpose of the present invention is to allow a gas to be stably discharged from a cracking valve even if a battery lid is deformed toward a wound group side. In a rectangular secondary battery of the present invention, a curved surface portion of a flat wound group is disposed on the side of an opening of a battery can, and the opening is sealed with a battery lid having a cracking valve and a liquid injection port. At least a protruding portion having a facing surface positioned on a curved surface portion side with respect to the cracking valve is disposed on the battery lid between the liquid injection port and the cracking valve.

摘要： A non-aqueous electrolyte secondary battery, when using an aqueous binder as a binder for a negative electrode active material, effectively exhausts the gas generated from an electrode, and thus, even when using it for a long period of time, a decrease in battery capacity is low. The non-aqueous electrolyte secondary battery includes a positive electrode active material layer on a surface of a positive electrode current collector, a negative electrode active material layer comprising an aqueous binder on a surface of a negative electrode current collector, a separator for maintaining an electrolytic solution, and a gas releasing means for releasing a gas generated within the power generating element to an extra space inside of the outer casing, and in which the ratio value of a volume of the extra space to a volume of pores included in the power generating element is 0.5 to 1.0.
