Research question
How does local phase heterogeneity control the redox reversibility and cycling of high-capacity, partially ordered manganese cathodes?
Key result
The cathode contained spinel-, rocksalt- and layered-like domains. Ti doping changed their balance and improved the reversibility of manganese and oxygen redox, increasing capacity retention.
Research contribution
Eunryeol Lee combined experiments with first-principles calculations. Dong-Hwa Seo co-designed and co-supervised the project with collaborators, relating the nanocomposite structure to electrochemical behavior.
