PCT No. PCT/FR89/00568 Sec. 371 Date May 2, 1991 Sec. 102(e) Date May 2, 1991 PCT Filed Nov. 2, 1989 PCT Pub. No. WO90/05387 PCT Pub. Date May 17, 1990.The invention relates to a composite element usable in an electrochemical generator. The element comprises a substrate (1) covered by cathodic sputtering with a layer (5) of amorphous material TiOaXB with X=S, Se or Te and 0.01a/=2, 0.01b/=3, 2/=a+b/=3. The layer (5) consitutes the positive electrode of the generator and it can be associated with a lithium negative electrode (9) and a lithium ion conductive glass electrolyte (7).
