<P>PROBLEM TO BE SOLVED: To solve problems of malfunction and heat generation trouble of an electronic device when a battery is mounted with wrong polarity of electrodes since a conventional lithium ion secondary battery uses a different material as an active material which structure a positive electrode and a negative electrode although the lithium ion secondary battery widely used as a power source of a portable electronic device becomes extremely difficult to indicate polarity of a terminal electrode as a size of the battery is made smaller. <P>SOLUTION: A battery, using a material for the active material functioning as the secondary battery even when a same material is used for the active materials for structuring the positive electrode and negative electrode, is developed, and a secondary battery with nopolarity is manufactured. Since the terminal electrodes are not distinguished, it is not necessary to pay attention to a mounting direction, and a mounting process can be simplified. In addition, since it is not necessary to manufacture a positive electrode layer and negative electrode layer separately, a manufacturing process of the battery can be also simplified. <P>COPYRIGHT: (C)2011,JPO&INPIT |
