Abstract
- In this investigation, a lithium-free cathode material, Na<subscript>0.7</subscript>MnO<subscript>2.05</subscript>–Na<subscript>0.91</subscript>MnO<subscript>2</subscript>, was synthesized by the solid phase method. The intercalation mechanism and partial phase transformation mechanism of NMO600 were clarified by in situ X-ray diffraction and impedance. The design of the heterostructure is favourable for improving the lithium ion storage of NMO600, which can deliver a discharge capacity of 83.12 mA h g<superscript>−1</superscript> at 1 A g<superscript>−1</superscript> and keep 61.71 mA h g<superscript>−1</superscript> after 700 cycles.
