ABSTRACT:
The invention provides an anode for an electrochemical cell. There is an anode holder containing a molten sodium anode. The holder is a ceramic envelope which is a sodium conductor and the holder has a current collector in contact with the sodium and projection through an opening in the envelope wall. The envelope interior contains a unitary porous solid matrix permeable by and impregnated by sodium. The matrix is bonded to at least part of the inner surface of the wall of the envelope. The invention provides also a holder for the anode which is empty of sodium; and provides an electrochemical cell employing the anode; and it provides a method of making said anode and holder.
