INVESTIGATION OF GLASS MATERIALS FOR NEW SOLID ELECTROLYTES AND THEIR ASSOCIATED CATHODES

Objective



A FRENCH TEAM OF THE UNIVERSITY OF BORDEAUX IN A SYSTEMATIC MATERIAL SEARCH DISCOVERED NEW GLASSY ELECTROLYTES (SULPHUR GLASS) WITH A VERY HIGH ION CONDUCTIVITY (10EXP-3 BY OHM, CM AT 25 DEGREES C). WITH THIS PROMISING MATERIAL, CELLS HAVE BEEN MADE, SIMILAR TO THOSE OF THE ANGLO-DANISH PROJECT. THE POSITIVE ELECTRODE CONSISTED OF A COMPOSITE MATERIAL (TIS2 + SULPHUR GLASS). SULPHUR GLASS WILL SERVE AS AN ELECTROLYTE AND LI OR LIAL WILL BE THE NEGATIVE ELECTRODE. THE USE OF COMPOSITES CONTAINING SULPHUR GLASS WILL ALLOW LOW COST MANUFACTURING OF THE ELECTROLYTE AND THE POSITIVE ELECTRODE IN A SINGLE GLASS BLOCK THUS AVOIDING INTERFACE PROBLEMS. THE FIRST CELLS OF THE TYPE LIAL/TERNARY GLASS ELECTROLYTE/TIS2 HAVE BEEN TESTED. THE TESTS, CARRIED OUT AT ROOM TEMPERATURES, GAVE ENCOURAGING RESULTS AND THERE IS GOOD HOPE THAT THESE CELLS CAN BE FURTHER DEVELOPED INTO HIGH ENERGY BATTERIES FOR TRANSPORT APPLICATIONS.
