Lattice expansion of MnO induced by sulphur doping for enhanced aqueous zinc-ion diffusion and storage†
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 MnOS0.3@rGO exhibits superior rate capability and reversible capacity of 115.1 mA h g−1 at 0.5 A g−1 for 350 cycles.
