Note: The project proposal MASSIF aims at improving the fundamental understanding and control of interfaces of a battery type based on Li active materials all solid state batteries (ASSLB). The main objective is the investigation and optimization of the interfaces developing between the solid electrolyte and the electrochemically active material particles electrodes. The acquired knowledge would allow the design of optimized interfacial layers (also called artificial Solid Electrolyte Interfaces, art-SEI) capable of warrant stable interfaces. The art-SEI should allow intimate contact between the active material and the conductive particles. Our research program involves hybrid electrolytes in combination with solid state electrolytes (SSE); this approach proves to be useful to generate an art-SEI. We are going to pay attention to the positive electrode-solid electrolyte interface, which has been studied as much as the metal Li solid electrolyte interface. With this in mind, they are going to use Li2S as a positive electrode, and the last task of the project will develop a full cell using Si as a negative electrode. Si was selected as a negative electrode to avoid the problems related to Li; it is known that Li reacts with most of the SSE.
The project also takes in to account the training of the researcher and the career development plan to achieve the goals and independence of the researcher. The interdisciplinary and network of the host institution will be also used to push the career of the researcher forward.
