Abstract
diffusivity compared to conventional routes. This work establishes reaction sequence as a powerful synthetic lever─beyond composition or carbon source type─for engineering interfacial structures. It opens a generalizable approach for tuning surface chemistry and boosting performance in carbon-coated phosphate cathodes and other electrode materials.
