ABSTRACT:
A one-piece galvanic solid element can be produced by directly polymerizing acetylene onto the surfaces of a disc-shaped ceramic solid electrolyte, using Ziegler-Natta catalysts. Starting from the polyacetylene layers so formed, negative electrode polarity is imparted to one layer and positive electrode polarity to the other layer, through immersion of the element in a suitable doping solution (e.g. NaPF.sub.6 in CH.sub.2 Cl.sub.2) and electrochemical polarization. As electrolyte material there can be used .beta.-Al.sub.2 O.sub.3, and mixed crystal compounds such as Na.sub.3 Zr.sub.2 Si.sub.2 PO.sub.12, which are Na-ion conductive, or Li-ion conductive Li.sub.3 N. Replacement of the negative polyacetylene electrode with Li or Na is possible.
