1. A bipolar battery having a plurality of cells with each of said cells comprising:
- a negative electrode;
a positive electrode and a separator element disposed between said negative electrode and said positive electrode, said separator element electrically insulating said electrodes from one another;
an electrolyte disposed within at least one of said negative electrode, said positive electrode and said separator element where said electrolyte is in contact with both said electrodes; and
an electrode containment structure including a cup-like electrode holder, a perimeter metallic seal ring forming a negative electrode compartment and a peripheral ceramic seal ring electrically isolating said positive and negative electrodes.
