Abstract: Prussian Blue Analogue (PBA)-Zn aqueous batteries are attractive because of the high potential of PBA against Zn (~1.7 V), relative safety of the system, and high rate capability. But, despite the long cycle life of PBA half-cells, full PBA-Zn battery systems studied thus far have typically reported only up to 100 cycles and suffer significant capacity fade beyond that. In this work we demonstrate that the loss in capacity retention and cycle life is a combined effect of Zn 2+ ion poisoning at the PBA cathode,… Show more

“…A relevant result of our work is the behavior of the (de‐)intercalation potential when solutions of mixed cations are used. It has been often implicitly assumed that the presence of two cations in solution would lead to a charge and discharge process taking place at two distinct potentials, corresponding to the intercalation of two different cations . Herein, we show that this does not necessarily happen; instead, in our experiments, a single characteristic potential is also observed in solutions with mixtures of ions.…”

“…An initial attempt on the hexacyanoferrate system delivered a limited capacity (≈60 mA h g −1 ), although a high operation voltage of ≈1.7 V was achieved. [23][24][25][26][27][28] Recently, Pan et al demonstrated that the manganese oxide cathode goes through a chemical conversion reaction with the zinc species and H 2 O rather than the simple intercalation process, delivering a high capacity of ≈285 mA h g −1 and an operating voltage of ≈1.44 V. [29] Nazar's group developed a Zn 0.25 V 2 O 5 ·nH 2 O cathode material, which displayed a specific energy of ≈250 Wh kg −1 (based on cathode) and a high capacity of 220 mA h g −1 at 15 C (1 C = 300 mA g −1 ). [30] During cycling, the structural water in Zn 0.25 V 2 O 5 ·nH 2 O was revealed to exchange with Zn 2+ reversibly, thus resulting in good kinetics and rate performance.…”

“…Aqueous Zn–Ni, Zn–polymer, Zn–air, and Zn–ion batteries are reported . The commercialization prospects of secondary Zn‐based batteries are still elusive because of a severe problem: dendrite formation on the Zn anode after successive charge–discharge cycles . Furthermore, the corrosion and hydrogen gas evolution on the Zn anode are major side reactions …”

“…Dendrite formation on the Zn electrode is a natural but complicated problem . When the Zn battery is working, Zn is stripped off the surface to create Zn 2+ under battery discharge, and the Zn 2+ deposits on Zn under battery charge.…”
