20130249498 | NON-AQUEOUS SECONDARY BATTERY AND SECONDARY BATTERY SYSTEM - A non-aqueous secondary battery, such as a lithium ion secondary battery, eliminates local potential distribution in a cell due to the side reaction during charge/discharge, and does not undergo deterioration of capacitance, deterioration of a positive electrode material, and deposition of metallic lithium. The non-aqueous secondary battery has an electrode group and an electrolyte disposed in one container. The electrode group includes a positive electrode, a negative electrode, and a separator, and is divided into a plurality of electrode groups separated electrically. The electrode groups are in contact with an identical electrolyte, and terminals are led out from the positive electrode and the negative electrode to the outside of the container on every electrode group. Terminals are connected on every positive electrode and negative electrode at the outside of the container, and the terminals at the outside of the container are connectable and disconnectable easily. | 09-26-2013 |
