COMPOSITE ELEMENT COMPRISING A TITANIUM CHALCOGEN OR OXYCHALCOGEN LAYER, SUITABLE IN PARTICULAR FOR USE AS A POSITIVE ELECTRODE IN A THIN-LAYER FUEL CELL

摘要

The invention relates to a composite element usable in an electrochemical generator. This element comprises a substrate (1) covered by sputtering with a layer (5) of amorphous material TiOaXb with X = S, Se or Te, O a 2, O b 3, 2 a + b 3. The layer (5) constitutes the positive electrode of the generator and it can be associated with a negative electrode (9) made of lithium and an electrolyte (7) made of glass conductive by lithium ions.
