Special Issue Information

Dear Colleagues,

Aqueous rechargeable batteries have attracted growing interest for energy storage due to their advantages of low price and high safety. The ionic conductivity of aqueous electrolytes is generally one order of magnitude higher than non-aqueous electrolytes, which endow high-power capability in aqueous batteries. Furthermore, aqueous batteries can also demonstrate high voltage and high energy density, thanks to the development of highly concentrated electrolytes and aqueous/non-aqueous hybrid electrolytes.

To date, substantial progress has been made in aqueous batteries, such as the reaction mechanisms, electrode materials, electrolytes, and full cell assembly. However, there exist certain pitfalls and many challenges in the aqueous battery research field. To better promote the development of aqueous batteries, we invite research articles, reviews, and perspectives from researchers all over the world.

Topics include but are not limited to:

  • Aqueous batteries with various charge carriers (monovalent, multivalent, and anions).
  • Novel working mechanisms or configuration of aqueous batteries.
  • Electrode materials, electrolytes, separators, etc.
  • Difference between non-aqueous and aqueous batteries.
  • Pitfalls in aqueous battery research.
  • Challenges that hinder aqueous battery development.

The impact of global warming has required the development of efficient new types of batteries. One of the most promising is Zn-O2 batteries because they provide the second biggest theoretical energy density, with relevant safety and a cycle of life long enough to be fitted for massive use. However, their industrial use is hindered by a series of obstacles, such as a fast reduction in the energy density after the initial charge and discharge cycles and a limited cathode efficiency or an elevated overpotential between discharge and charge. This work is focused on the synthesis of titanium compounds as catalyzers for the cathode of a Zn-O2 aqueous battery and their characterization. The results have shown a surface area of 350 m2/g after the elimination of the organic templates during heat treatment at 500 °C in air. Different thermal treatments were performed, tuning different parameters, such as intermediate treatment at 500 °C or the atmosphere used and the final temperature. Surface areas remain high for samples without an intermediate temperature step of 500 °C. Raman spectroscopy studies confirmed the nitridation of samples. SEM and XRD showed macro–meso-porosity and the presence of nitrogen, and the electrochemical evaluation confirmed the catalytic properties of this material in oxygen reaction reduction (ORR)/oxygen evolution reaction (OER) analysis and Zn-O2 battery tests.

Aqueous zinc-ion batteries (AZIBs) are considered hopeful large-scale electrochemical energy storage devices because of their simple production process, high specific capacity, intrinsic safety and low cost. However, the dendritic growth of Zn and side reactions cause rapid battery performance degradation, which limits the application of AZIBs for large-scale energy storage. In this work, following the addition of tetraethylene glycol dimethyl ether (TEGDME) to 1 mol L−1 (M) Zn(CF3SO3)2 aqueous electrolyte as a cosolvent, the 1 M Zn(CF3SO3)2/TEGDME-H2O (1:1 by volume) hybrid electrolyte showed enhanced battery performance resulting from the expanding electrochemical window, inhibiting the growth of zinc dendrites and the parasitic reactions on the negative Zn electrode. The experimental results show that this hybrid electrolyte enabled a high coulombic efficiency (CE) of >99% for 200 cycles in the Zn||Cu battery and a steady discharge/charge property for 1000 h with a low overpotential of 100 mV at 1 mA cm−2 (the capacity: 1.13 mAh) in the Zn||Zn battery. Remarkably, Zn||V2O5 batteries with the hybrid electrolyte also performed much better in terms of cycling stability than a device with a 1 M Zn(CF3SO3)2 aqueous electrolyte. Zn||V2O5 batteries delivered a high specific capacity of 200 mAh g−1 with an average CE of >99.9% after 1500 cycles at 0.5 A g−1. This study provides a promising strategy for the development of high-performance electrolyte solutions for practical rechargeable AZIBs. Full article

We report an effective processing route, combining nanostructure formation and hybridization, to improve the rate performance of the tunnel-structure sodium manganese oxide Na0.44MnO2 (NMO) as a cathode material for aqueous sodium ion storage. We use hydrothermal synthesis to prepare an NMO/CNF (Carbon NanoFiber) hybrid, consisting of uniform oxide nanowires with an average width of 70 nm and length in the range of several tenths of µm. The highly dispersed CNFs impart high conductivity to the NMO/CNF electrode, allowing high-rate performance at a C-rate of up to 20 C, with a delivered capacity of more than half the theoretical value in a 1 M Na2SO4 electrolyte. Moreover, the NMO/CNF hybrid shows good electrochemical stability under several hundred cycles at a high C-rate. However, the NMO nanowire electrodes reveal a lower-than-expected capacity, probably as a result of the tendency of nanowires to form bundles, which prevents direct contact with conductive fibers and induce the under-utilization of active material. With this study, we demonstrate a strong improvement of the otherwise inherently low-rate performance of NMO through oxide nanostructuring and hybridization with carbon fibers, paving the way for further research on NMO-based materials for aqueous sodium ion storage.

Aqueous sodium-ion batteries (ASIBs) represent a promising battery technology for stationary energy storage, due to their attractive merits of low cost, high abundance, and inherent safety. Recently, a variety of advanced cathode, anode, and electrolyte materials have been developed for ASIBs, which not only enhance our fundamental understanding of the Na insertion mechanism, but also facilitate the research and development of practical ASIB systems. Among these electrode materials, iron-based materials are of particular importance because of the high abundance, low price, and low toxicity of Fe elements. However, to our knowledge, there are no review papers that specifically discuss the properties of Fe-based materials for ASIBs yet. In this review, we present the recent research progress on Fe-based cathode/anode materials, which include polyanionic compounds, Prussian blue, oxides, carbides, and selenides. We also discuss the research efforts to build Fe-based ASIB full cells. Lastly, we share our perspectives on the key challenges that need to be addressed and suggest alternative directions for aqueous Na-ion batteries. We hope this review paper can promote more research efforts on the development of low-cost and low-toxicity materials for aqueous battery applications. Full article
