The development of solid-state batteries opens up a major challenge by modifying the liquid electrolyte to a solid material that has to be compatible with both the anode and cathode material and causes the contact phases between materials to become unstable during cycling. The formulation process of the materials can condition the stability and final behavior of the material at the system interfaces.

Know in detail the characteristics of the material to be formulated (particle size, temperature range of use,...) and carry out the surface modifications that give it greater chemical and electrochemical stability.
