It is difficult to display the polarity of terminal electrodes of lithium ion batteries. With conventional lithium ion secondary batteries, since different materials are employed for the active substances that make up a positive electrode and a negative electrode, problems arise if the polarities of the electrodes are mistaken when the battery is installed. A battery has been developed using an active substance material functioning as a secondary battery even when the same material is used for the active substances that make up the positive electrode and the negative electrode, and a non-polar secondary battery has been produced. With no distinction between the terminal electrodes, attention does not need to be paid to the direction of installation, thereby simplifying the installation step. Furthermore, since there is no need to manufacture a positive electrode layer and a negative electrode layer separately, the step for manufacturing the battery is also simplified. |
