Current blocking element assembly and product having current blocking element assembly

A current blocking element assembly comprising a first current blocking element and a second current blocking element,

• the first current blocking element comprising:
• a first-A electrode layer configured to hold ions;
• a first ion conductive layer that is configured to conduct ions and does not have electronic conductivity;
• and
• a second-A electrode layer configured to hold ions,
• the first-A electrode layer, the first ion conductive layer, and the second-A electrode layer being laminated in this order,
• the second current blocking element comprising:
• a first-B electrode layer configured to hold ions;
• a second ion conductive layer that is configured to conduct ions and does not have electronic conductivity;
• and
• a second-B electrode layer configured to hold ions,
• the first-B electrode layer, the second ion conductive layer, and the second-B electrode layer being laminated in this order,
• wherein the second-A electrode layer and the second-B electrode layer are electrically connected;
• wherein ions held in one of the electrode layers of the first current blocking element are moved to the other one of the electrode layers of the first current blocking element when current is configured to flow between the first-A electrode layer and the first-B electrode layer;
• and
• wherein current flow between the first-A electrode layer and the second-A electrode layer is blocked when ions held in one of the first-A and second-A electrode layers of the first current blocking element are depleted or saturated.
