Abstract
Owing to the high theoretical capacity, O3-type Ni–Fe–Mn-based layered oxides are one of the cathodes with the greatest potential for high-energy Na-ion batteries (NIBs). However, their poor cycling life and air stability greatly limit their practical application. Herein, we synthesized single-crystalline O3–Na0.95Ni0.4Fe0.2Mn0.4O2 (SC-NFM424) with a preferred orientation of the (003) facet by a simple resintering method, which delivered a high capacity of 172.3 mA h g–1 and stable cycling stability (80.0% after 450 cycles at 1 C). The various characterizations confirm that SC-NFM424 can effectively suppress the side reactions and structural degradation during the charge/discharge process. Moreover, the…
