A study on the dehydration reactions analysis of cathode material sintering process for enhancing the performance and durability of lithium-ion batteries

The research team, led by Professor Hong Jongseop from the Department of Mechanical Engineering (co-first authors of this study are Jaeyoung Jeon and Minuk Kim), has collaborated with the RIST Secondary Battery Materials Research Institute to analyze dehydration reactions occurring during the sintering process of high Ni-based cathode materials. Dehydration reactions of each cathode material precursor were identified based on in-situ XRD and TGA-MS experiments, and the reaction rates of three identified dehydration reactions were analyzed using the Random Pore Model. This research has been published in the renowned international academic journal 'Journal of Materials Chemistry A' (Impact Factor: 11.9 as of 2022, ranking in the top 8.8% in the JCR Energy & Fuels category).
