| 摘要 |
The present invention provides a battery cell in which an electrode assembly is sealed with an electrolyte in a battery case. The electrode assembly comprises: one or more positive electrodes in which positive electrode terminals are connected; one or more first negative electrodes in which a first negative electrode terminal is connected; one or more second negative electrodes in which a second negative electrode terminal is connected; and separation membranes interposed between the positive electrode and the first negative electrode or the second negative electrode, or between the positive electrode and the first negative electrode or the second negative electrode, and between the first negative electrode and the second negative electrode. |
