Toward Zero-Waste and Net-Zero Synthesis of LiFePO₄ and LiMnxFe1-xPO4 (x=0.1 to 1) Cathodes for Sustainable Lithium-Ion Batteries - CME Seminar Series Winter 2026

A comprehensive study was conducted to advance zero-waste and net-zero emission production of LiFePO₄ (LFP). While previous research has investigated certain aspects of LFP synthesis, our work presents an integrated pathway for developing high-performance LFP chemistry, comparable to commercial LFP/C in both morphology and electrochemical performance. To address gaps in the existing literature, we assessed the environmental impact of LFP production by analyzing energy consumption, carbon emissions, and waste generation. Waste analysis identified a promising opportunity for lithium recovery and reuse. To increase the energy density of LFP materials, we studied durable LiMnxFe1-xPO4 (0.1 < x < 1). These findings demonstrate a viable path toward producing high-performance LFP, LMFP cathodes with a more sustainable, low-emission, and waste-reducing manufacturing approach.

About the speaker:
Dr. Atiyeh Nekahi earned her first Ph.D. in Materials Science and Engineering from Amirkabir University of Technology (Tehran Polytechnic), where her research focused on graphene-based hybrid nanomaterials. Following her doctoral studies, she collaborated with several universities and research institutions on both academic and industrial projects. She also served as an R&D specialist at an iron ore mining company, where she optimized iron extraction and beneficiation processes. Building on this industrial experience, she returned to academia to pursue a second Ph.D. in Chemical and Materials Engineering under the supervision of Professor Karim Zaghib, focusing on advanced research in lithium-ion battery materials. She’s currently working on novel cathode materials to enhance energy density, safety, and durability of lithium-ion batteries.
