Abstract

Lattice engineering is reported to enhance Zn²⁺ storage capability of MnO via anionic doping, which effectively lowers the Zn²⁺ diffusion barrier and boosts Zn²⁺ diffusion kinetics. The optimized MnOS_0.3@rGO exhibits superior rate capability and reversible capacity of 115.1 mA h g⁻¹ at 0.5 A g⁻¹ for 350 cycles.
