Abstract

P2-type Na<sub>0.4</sub>Mn<sub>0.54</sub>Co<sub>0.46</sub>O<sub>2</sub>nanosheets were facilely synthesized<italic>via</italic>a two-step annealing route, which showed a high second charge capacity of 194 mA h g<sup>−1</sup>and delivered as specific capacity of 125 mA h g<sup>−1</sup>at a current of 20 mA g<sup>−1</sup>after 60 cycles.
