Phase Transitions and Ion Transport in Lithium Iron Phosphate by Atomic-Scale Analysis to Elucidate Insertion and Extraction Processes in Li-Ion Batteries Nikola Šimić, Anna Jodlbauer, Michael Oberaigner, Manfred Nachtnebel, Stefan Mitsche, H. Martin R. Wilkening, Gerald Kothleitner, Werner Grogger, Daniel Knez, Ilie Hanzu Advanced Energy materials 2024, 2304381 Abstract Lithium iron phosphate (LiFePO4, LFP) serves as a crucial active material in Li-ion batteries due to its excellent cycle life, safety, eco-friendliness, and high-rate performance. Nonetheless, debates persist regarding the atomic-level mechanisms underlying the electrochemical lithium insertion/extraction process and associated…
