Dr. Sougrati is a CNRS Research Engineer and a member of the D4 Department at the Institut Charles Gerhardt Montpellier (ICGM). His research activities lie at the interface of electrochemical energy storage materials and chemistry for the circular economy, with a strong focus on sustainable and low-impact approaches. In recent years, his work has increasingly concentrated on the direct recycling and regeneration of Li-ion battery materials, aiming to preserve the functional properties of electrode materials while avoiding energy-intensive metallurgical routes. In particular, he develops innovative chemical strategies for the direct recycling of cathode materials such as LiFePO₄ (LFP) and LiMnFePO₄ (LMFP), as well as anode materials, including graphite and Si-containing graphite composites. These activities address key challenges related to material purity, performance recovery, and integration of recycled materials into battery manufacturing, in line with emerging industrial and regulatory requirements. In parallel, Dr. Sougrati maintains strong expertise in the investigation of electroactive materials for A-ion batteries (A=Li, Na, K), as well as PGM-free electrode materials for fuel cells. He is also in charge of the Mössbauer spectroscopy platform, where he has developed advanced in situ and operando methodologies for the study of energy materials. The Mössbauer facilities, now integrated within a UAR structure, are open to both academic and industrial users in France and internationally.
