Summary: In this study, Mo-doped a-MnO2 was chosen as the cathode material and a stable N-H bond reinforced interaction was formed via NH4+ intercalation to stabilize the 2 x 2 tunnel structure of Mo-MnO2. Theoretical and experimental studies demonstrated the improved performance of the cathode in terms of cyclic stability and electrochemical performance. This work provides further understanding of the bond interaction between nonmetallic cations in the main materials of electrodes and contributes to the development of aqueous-based zinc-ion batteries with high energy density and long-term cycling capability.

Summary: The study fabricated an aqueous Zn2+/Li+ hybrid-ion battery using LiV3O8 nanorods as cathode, metallic Zn as anode, and 3M Zn(OTf)(2) + 0.5M LiOTf aqueous solution as electrolyte. The hybrid-ion battery showed significantly improved cycle performance compared to batteries using pure 3M Zn(OTf)(2) electrolyte, with an impressive capacity retention of 87.0% after 4000 cycles at 5A g(1), due to the inhibitory effect of the hybrid electrolyte on the formation of irreversible by-products and Zn dendrite growth.

Summary: In this study, a high-capacity and high-voltage Zn-ion battery using a polymer cathode and two ion-selective membranes for separating acidic and alkaline electrolytes is reported. The cathode, prepared by electrodepositing poly(4,4'-oxydianiline) onto mesoporous activated carbon, delivers a high areal capacity of 5.42 mAh cm-2. Due to the use of different electrolytes at the cathode and anode sides, this aqueous Zn-organic battery operates within an elevated voltage window of 1.3-2.5 V and exhibits a high discharge median voltage of -2 V. Furthermore, the optimization of electrolyte concentration and the use of additives to improve the Zn anode performance are systematically studied.

Summary: Aqueous rechargeable MnO2-Zn batteries have high security, low cost and environmentally friendly nature. However, the slow reaction kinetics and the poor cycle life of MnO2 cathode materials limit their practical application. In this study, oxygen-defect-rich β-MnO2(O-d) nanorods were successfully prepared, and the oxygen defects were found to improve the electrical conductivity and proton adsorption capability. The tested Zn//β-MnO2(O-d) batteries exhibited impressive specific capacity and capacity retention rate.

Summary: In this study, the capacity decay mechanism of Zn-MnO2 batteries with manganese acetate as an electrolyte additive was demonstrated. It was found that zinc hydroxide sulfate has a beneficial effect on the battery capacity, but the product ZnMn3O7·2H₂O converted from basic zinc sulfate is an irreversibility inert material leading to rapid capacity fading. Notably, with an increased low cutoff voltage, the battery showed a high capacity and excellent stability. This research provides a new perspective for the development of Zn-MnO2 batteries.
