Summary: Due to its high safety and environmental friendliness, aqueous zinc-ion batteries have attracted much attention recently. Prussian blue and its analogues are regarded as promising cathode materials. Among them, manganese hexacyanoferrate is suitable due to its high operating voltage, large capacity, and low price. However, the poor cycling stability of manganese hexacyanoferrate, mainly caused by transition metal dissolution, side reaction, and phase transition, severely limits its practical application. In this study, gelatin is used to reduce the dissolution effect of transition metal manganese by limiting the content of free water in the electrolyte. Gelatin also improves the durability of the Zn anode. The optimized MnHCF/gel-0.3/Zn battery exhibits high reversible capacity (120 mAh center dot g(-1) at 0.1 A center dot g(-1)), excellent rate performance (42.7 mAh center dot g(-1) at 2 A center dot g(-1)), and good capacity retention (65% at 0.5 A center dot g(-1) after 1000 cycles).

Summary: Aqueous zinc-ion batteries (ZIBs) have brought new opportunities and challenges to the energy storage market due to their low price, high safety, and environmental friendliness. Among the cathode materials, MnO2 is considered one of the most promising materials for ZIBs due to its high theoretical capacitance, abundant reserves, non-toxicity, and low cost. However, the cycling stability and rate performance of MnO2 have been limited by slow electrochemical kinetics and structural damage. To address this issue, a surface modification of manganese hexacyanoferrate (MnHCF) is proposed to optimize the cycling stability and rate performance of MnO2. The modified MnO2 composite shows improved cycling stability and retains a high initial capacity after multiple cycles.

Summary: Potassium manganese hexacyanoferrate (KMHCF) is a promising cathode material for potassium-ion batteries (PIBs) due to its impressive electrochemical performance, abundant elements, and easy synthesis. However, the capacity fading and poor K+ diffusion kinetics hinder its large-scale application. In this study, Mn-Ni Prussian blue analogue (MnNi-PBA) spheres were synthesized using a facile anion exchange method. The addition of Ni stabilizes the structure and provides rich active sites, leading to improved cycling performance and shorter ion diffusion pathways. The MnNi-PBA sphere cathode exhibits high initial discharge capacity, enhanced rate capability, and long cycle life. The reversible structural changes (monoclinic <-> cubic) of MnNi-PBA spheres are observed during cycling. These findings provide a design strategy for Mn-based Prussian blue analogues in PIBs.
