STUDY OF NEW SOLID ELECTROLYTES AND ASSOCIATED CATHODES. STUDY AND REALIZATION OF NEW "ALL SOLID" GENERATORS
The use of "all solid" secondary generators functioning at environmental temperature calls for the use of a solid electrolyte with high ionic conductivity, negligeable electronic conductivity, and chemically and electronically stable vis-a-vis the electrodes. This generator must also tolerate a positive electrode material with considerable mass energy. A major part of this study is directed towards obtaining materials with these qualities. Crystalline and vitrous materials were studied for the electrolyte. The low conductivity obtained in the first case led to a concentration of effort on numerous groups of amorphous materials with borate and lithium chalcoborate bases (sodium glasses have a lower systematic conductivity than glasses containing lithium). Work has been conducted simultaneously on intercalation compounds of type A-xMO-2 (A = Li, Na; M = element 3d) which may be suitable for use as the material for the positive electrode.
