STUDY OF AMORPH SOLID ELECTROLYTES AND ELECTRODES AND CONSTRUCTION OF "ALL SOLID" BATTERIES.

Objective

INCREASE THE POWER DENSITY AND NUMBER OF (CHARGING-DISCHARGING) CYCLES OF SMALL ALL SOLID BATTERIES FOR WHICH ENERGY DENSITIES OF 120 WK HAVE BEEN OBTAINED IN THE PREVIOUS CONTRACT (EE-E2-421).

DEVELOPMENT OF NEGATIVE ELECTRODES CONSISTING OF LI COMPOUNDS IN WHICH LI CAN DIFFUSE RAPIDLY. THIS IN ORDER TO AVOID LOCAL DEPLATION OF LI AS THE ELECTROLYTE-ELECTRODE INTERFACE.

INCREASE THE LI ION CONDUCTIVITY IN THE GLASS ELECTROLYTE (B2B3-LI2S-LI1)

IMPROVEMENT OF THE POSITIVE ELECTRODE CONSISTING OF A NI FELT WITH 97% POROSITY IN WHICH THE LIS2 INTERCALATION MATERIAL AND SOME LECTROLYTE MATERIAL IS INTRODUCED. THE POROSITY AND THE RELATIVE QUANTITIES OF LIS2 AND THE ELECTROLYTE WILL BE OPTIMISED.

CONSTRUCTION OF A BATTERY OF SEVERAL AH.
