Abstract

This project proposes the development of new Cathode Active Materials (CAMs) based on LiMn0.6Fe0.4PO4 (LMFP), doped with Nb and/or Mg, using metal glycerolates (M-Glys) as precursors for the first time. This innovative approach aims to enhance the energy density and electrochemical stability of cathodes, contributing to the advancement of next-generation lithium-ion batteries. In addition to its methodological originality, the project promotes the valorization of glycerol-a byproduct of the biodiesel industry-thus aligning with principles of sustainability and circular economy. Over a 12-month period, the research fellow will work on the synthesis and characterization of M-Glys and CAMs, developing expertise in modern physicochemical and electrochemical techniques, with the potential to generate scientific publications and patents. The project represents a significant step forward in the field of energy storage and supports the training of highly qualified human resources. (AU)
