Abstract: Lattice engineering is reported to enhance Zn<superscript>2+</superscript> storage capability of MnO via anionic doping, which effectively lowers the Zn<superscript>2+</superscript> diffusion barrier and boosts Zn<superscript>2+</superscript> diffusion kinetics. The optimized MnOS<subscript>0.3</subscript>@rGO exhibits superior rate capability and reversible capacity of 115.1 mA h g<superscript>−1</superscript> at 0.5 A g<superscript>−1</superscript> for 350 cycles.
