Title:
POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/097849
Kind Code:
A1
Abstract:
This power storage device is provided with a case, an electrode assembly housed inside of the case, a first conductive plate arranged between the case and the electrode assembly, a second conductive plate arranged between the case and the first conductive plate, and an insulating member arranged between the first conductive plate and the second conductive plate. The electrode assembly is provided with a positive electrode, a negative electrode, and a separator arranged between the positive electrode and the negative electrode. The first conductive plate is electrically connected with one of the positive electrode and the negative electrode, and the second conductive plate is electrically connected with other of the positive electrode and the negative electrode. The rigidity of the first conductive plate is higher than that of the positive electrode or the negative electrode of the electrode assembly nearest to the first conductive plate, and the rigidity of the first conductive plate is higher than that of the second conductive plate.
