Abstract
A bipolar battery having a plurality of cells. The bipolar battery includes: a negative electrode; a positive electrode and a separator element disposed between the negative electrode and the positive electrode, the separator element electrically insulating the electrodes from one another; an electrolyte disposed within at least one of the negative electrode, the positive electrode and the separator element; and an electrode containment structure including a cup-like electrode holder.
Claims23
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.
