A High‐Rate and Long‐Life Aqueous Rechargeable Ammonium Zinc Hybrid Battery

Abstract

Unlike traditional metal-ion insertion, the emerging aqueous rechargeable ammonium-ion batteries (ARABs)b rings new battery chemistries for future stationary energy storage. However, low energy density and low durability hindert he further development of ARABs because of the lack of suitable and cost-efficient anodes. In this study,a na queous rechargeable ammonium zinc hybrid battery is fabricated from durable corner-truncated sodium iron hexacyanoferraten anocubes as the cathode and low-cost zinc as the anode. This novel hybridb attery demonstrates an average workingv oltage of 1.3 V, excellent rate capability,a nd ah igh energy density of 81.7 Wh kg À1 at 286 Wkg À1 (based on two electrodes' active mass), as well as a long lifespan with 92.

Ammonium‐Ion Storage Using Electrodeposited Manganese Oxides

“…in 2012, [3] achievements have been made on NH 4 + storage for aqueous energy storage (Figure 1). Ti 3 C 2 MXene, [4] Prussian blue analogues (e.g., sodium iron hexacyanoferrate, [5] copper hexacyanoferrate, [6] berlin green, [7] ammonium Prussian white [2] ), organic solids (e.g., 3,4,9,10‐perylenetetracarboxylic diimide, [2] polyaniline [8] ), and metal oxides (e.g., titanic acid, [9] V 2 O 5 , [10] MoO 3 , [11] NH 4 V 4 O 10 [8] ) were studied to enrich the NH 4 + ‐storage chemistry. For example, Ji et al.…”

Common ion effect enhanced Prussian blue analogues for aqueous ammonium ion storage

“…3e shows the multifaceted performance comparison between FeHCF and other representative PBA electrodes. 34,49,51 As can be seen, our material shows the highest capacity, the lowest polarization and better cycling stability, demonstrating a better comprehensive performance.…”

Recent Progress on High‐Performance Cathode Materials for Zinc‐Ion Batteries

“…Despite its remarkable cycling stability of 92.1% after 2000 cycles at 2 A g −1 , its low working voltage of 1.3 V is not ideal. [ 85 ] In subsequent work, the same group selected CuHCF as the cathode due to its high operating potential. [ 86 ] They verified the intercalation/deintercalation of NH 4 + by comparing the CV curves of 1 m (NH4) 2 SO 4 and dilute H 2 SO 4 at pH near 5.4.…”
