| 摘要 |
The purpose of the present invention is to enable positive and negative electrode voltage levels to be accurately measured and facilitate positioning of a reference electrode during battery assembly without increasing the number of constituent components of the battery. A lithium-ion secondary battery separator has a reference electrode and an insulating porous material, wherein the insulating porous material holds the reference electrode from both sides thereof and the reference electrode and the insulating porous material are integrated with each other. The reference electrode has a metal portion and a reference electrode measurement portion, wherein the metal portion is formed in a mesh, a frame shape, or a serpentine shape. |
