On December 11 a joint meeting of the Materials Discovery Laboratory and the Energy Center was held. Chaired by Distinguished Professor Artem R. Oganov, the focus of the meeting was the presentation of the doctoral dissertation by Distinguished Professor Artem Abakumov, the director of the Energy Center. He was discussing cathode materials for metal-ion batteries, specifically exploring oxides and chalcogenides of transition metals with layered structures.
Abstract:
Overcoming the technological barrier in specific energy of Li-ion battery cells of 300 Wh/kg by 2025 and 350 Wh/kg by 2030 calls for advanced cathode materials, such as layered transition metal oxides providing electrochemical capacity up to ~220-270 mAh/g. The talk will offer a comprehensive vision of the complex interplay between the chemical composition, crystal and electronic structure of the cathodes based on layered oxides and chalcogenides, defect structure, microstructural organization, electrochemical properties, and electrochemically induced structural and chemical evolution at the nanoscale or even atomic scale with the help of advanced transmission electron microscopy.
