Abstract

A monolithic ceramic electrochemical cell housing is provided. The housing includes two or more electrochemical sub cell housings. Each of the electrochemical sub cell housing includes an anode receptive space, a cathode receptive space, a separator between the anode receptive space and the cathode receptive space, and integrated electron conductive circuits. A first integrated electron conductive circuit is configured as an anode current collector within the anode receptive space. A second integrated electron conductive circuit is disposed as a cathode current collector within the cathode receptive space.
