Designing Metastable P3‐type Layered Negative Electrodes with High Na Vacancy Concentration for High‐Power Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A metastable high‐vacancy concentration layered P3‐type Na0.5Cr0.5Ti0.5O2 negative electrode material has been synthesized from its K analogues P3‐type K0.5Cr0.5Ti0.5O2 using a facile room temperature ion‐exchange method. The P3‐type Na0.5Cr0.5Ti0.5O2 demonstrates a gravimetric capacity of 125 mA h g−1 and high‐rate performance (80% charging in 3 min ...
