Seminar - “Exploring Anionic Oxygen Activity in Li-Rich Layered Oxide Cathodes” by Wei Tong, Scientist/Principal Investigator, Energy Storage and Distributed Resources Division, Lawrence Berkeley National Laboratory
ABSTRACT: In commercial Li-ion batteries, well-ordered close-packed oxides, particularly, layered lithium transition metal oxides, LiTMO2 (TM = Ni, Mn, Co, Al), are widely used. Despite the high theoretical capacity of these layered oxides (> 270 mAh/g), they are typically operated to deliver a capacity of less than 200 mAh/g to attain good cycling and safety attributes.
