Rate-Dependent Stability and Electrochemical Behavior of NaNiZr(PO) in Sodium-Ion Batteries.

In advancing sodium-ion battery technology, we introduce a novel application of NaNiZr(PO) with a NASICON structure as an anode material. This research unveils, for the first time, its exceptional ability to maintain high specific capacity and unprecedented cycle stability under extreme current densities up to 1000 mA·g, within a low voltage window of 0.01-2.
