Toward Zero-Waste and Net-Zero Synthesis of LiFePO₄ and LiMnxFe1-xPO4 (x=0.1 to 1) Cathodes for Sustainable Lithium-Ion Batteries - Fall 2025 CME Seminar Series

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 worked on durable LiMnxFe1-xPO4 (x=0.1 to 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.
