Abstract

Component modulation endows Mn-based electrodes with prominent energy storage properties due to their adjustable crystal structure characteristics. Herein, ZnMn₂(PO₄)₂·nH₂O (ZMP·nH₂O) was obtained by a hydration reaction from ZnMn₂(PO₄)₂ (ZMP) during an electrode-aging evolution. Benefiting from the introduction of lattice H₂O molecules into the ZMP structure, the ion transmission path has been expanded along with the extended d-spacing, which will further facilitate the ZMP → ZMP·nH₂O phase evolution and electrochemical reaction kinetics. Meanwhile, the hydrogen bond can be generated between H₂O and O in PO₄^3-, which strengthens the structure stability of ZMP·nH₂O and lowers the conversion barrier from ZMP to ZMP·4H₂O during the Zn²⁺ uptake/removal process. Thereof, ZMP·nH₂O delivers enhanced electrochemical reaction kinetics with robust structure tolerance (106.52 mA h g^-1 at 100 mA g^-1 over 620 cycles). This high-energy aqueous Zn||ZMP·nH₂O battery provides a facile strategy for engineering and exploration of high-performance ZIBs to realize the practical application of Mn-based cathodes.
