  • Polyacetylene cell with ceramic solid electrolyte
    Patent number: 4557985
    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.

  • Galvanic cell with solid fluoride ion-conductive electrolyte
    Patent number: 3973990
    Abstract: In a galvanic cell, there is provided a solid fluoride ion-conductive electrolyte which is a compound having the formula M.sub.n Pb.sub.1.sub.-n F.sub.2.sub.-n wherein M is at least one element selected from the group consisting of potassium and rubidium; Pb is usually all lead but part of the lead may be replaced by metal more electropositive than lead; F is fluorine; and n is a positive value.
