An open holey structure enhanced rate capability in a NaTi₂(PO₄)₃/C nanocomposite and provided ultralong-life sodium-ion storage

Abstract

(88.3% retention of the 1st cycle) was delivered even after 10 000 cycles at an ultrahigh rate of 50C without any obvious morphological change and without structural pulverization. Forming open channels for ion transport proved to contribute to such performance enhancement and therefore has the potential to become a universal model for the development of sustainable electrode materials in SIBs and other battery systems.
