Abstract
transport channels and strengthens TM-O bonds, substantially reducing the energy barrier for ion migration and improving structural reversibility. This study underscores the potential of this approach to significantly enhance the cycle stability and specific capacity of O3-type layered oxide cathodes, promising for high-performance sodium-ion batteries.
