Project summary:

This project aims to obtain optimized tin-based nanocomposites using laser pyrolysis technique and to validate them as main component in performant anodes for Li-ion batteries. Combining Sn with other elements such as carbon, iron and/or silicon as mixed oxides, alloys, intermetallics, or as core-shell nanocomposites we hope to mitigate the drawbacks of pure tin (or silicon) materials which do not resist to multiple charge-discharge cycles due to pulverization induced by mechanical stress caused by a massive volume difference between unlithiated and lithiated form. The XRD, TEM, SEM, Raman analyzes of both raw nanoparticles and the materials resulted after anode cycling, corroborated with the Li-ion batteries specific electrochemical measurements will help to select the most peformant material and to optimize them in order to obtain an anode material with high capacity for energy storage which can withstand to a great number of charge-discharge cycles. As strategy of research, we will start with binary tin-containing nanopowders and, based on this experience and will continue with more complex ternary and cuaternary nanocomposites in order to maximize the chances to find the best combination from point of view of Li-ion batteries anode performances.
