“…Hong et al. ( Chae et al., 2017b ) reported Mg 2+ storage of NiHCF in organic electrolyte with a discharge capacity of 48.3 mAh g −1 at 0.2 C and an average discharge voltage of 2.99 V (versus Mg/Mg 2+ ). The authors found that the magnesium ions in NiHCF are positioned at the center of the large interstitial cavities.…”

SummaryNon-lithium energy storage devices, especially sodium ion batteries, are drawing attention due to insufficient and uneven distribution of lithium resources. Prussian blue and its analogs (Prussian blue analogs [PBAs]), or hexacyanoferrates, are well-known since the 18th century and have been used for hydrogen storage, cancer therapy, biosensing, seawater desalination, and sewage treatment. Owing to their unique features, PBAs are receiving increasing interest in the field of energy storage, such as their high theoretical specific capacity, ease of synthesis, as well as low cost. In this review, a general summary and evaluation of the applications of PBAs for rechargeable batteries are given. After a brief review of the history of PBAs, their crystal structure, nomenclature, synthesis, and working principle in rechargeable batteries are discussed. Then, previous works classified based on the combination of insertion cations and transition metals are analyzed comprehensively. The review includes an outlook toward the further development of PBAs in electrochemical energy storage.

“…In particular, rechargeable magnesium‐ion batteries (MIBs) have an appealing low cost, a high theoretical volumetric capacity (3833 mAh cm −3 for Mg and 2046 mAh cm −3 for Li), and a low toxicity. In addition, they are made with an abundant natural source (1.94 % for Mg and 0.006 % for Li) and Mg is deposited without the formation of dendrites . In spite of these highly attractive features, rechargeable batteries with Mg anode still face a series of challenges to improve the kinetically sluggish Mg diffusion in solid hosts, the incompatibility between the Mg anode and non‐aqueous electrolytes and the widening potential window .…”

Spinel Li₄Mn₅O₁₂ as 2.0 V Insertion Materials for Mg‐Based Hybrid Ion Batteries

With the increasing demand for electrical energy storage, a new Mg−Li hybrid battery with Mg anode is regarded as a promising candidate because of low cost, high volumetric capacity, and dendrite‐free nature of the Mg anode. Nevertheless, the characteristics of low operation voltage and low energy density for Mg−Li hybrid batteries hinders their widespread application, owing to limited reversible cathodes. To overcome these issues, a highly reversible fast Li+ insertion cathode with high voltage is an effective strategy to realize high‐energy‐density Mg−Li hybrid batteries. Herein, we develop the 2 V high‐voltage spinel Li4Mn5O12 cathode material with unique nano‐/microspheres, using a novel low‐temperature method, offering a short Li‐diffusion path and sufficient transport channels for electrolyte penetration into the electrode. For the first time, we demonstrate the feasibility of the spinel Li4Mn5O12 nano‐/microspheres with hierarchical architecture as a cathode for 2 V hybrid Mg−Li batteries. It exhibits a reversible specific capacity of 155 mAh g−1 and a long discharge voltage platform exceeding 2.0 V (vs. Mg/Mg2+) coupled with high energy density of 326 Wh kg−1 at a current density of 0.1 C (1 C=163 mA g−1). Our results pave the way of constructing new hybrid Mg−Li batteries with high voltage and high energy density.

“…Its structure is the same as the pristine ZPB except that the occupancy of the water increases. Prussian-blue analogues easily intercalate/deintercalate zeolitic water into/from its crystal structure, and its water content is dependent on synthetic and environmental conditions [15,48]. The initial ZPB phase contains a small amount of water content (0.22 H2O per formula unit of ZPB) according to TGA analysis ( Figures S6 and S8).…”

“…The powder XRD patterns of the Zn x ZPB electrodes were recorded with respect to the number of inserted zinc ions (x = 0, 0.25, 0.5, and 0.72) employed during the galvanostatic reduction, as shown in Figure 4c. Unlike cubic Prussian-blue analogues [15,48], the evolution of the patterns is complicated due to multiple insertion stages, as implied by the multiple quasi-plateaus in the discharge profile. An atomic-scale structural analysis would be crucial to understanding the insertion mechanism.…”

Zinc-ion batteries (ZIBs) have received attention as one type of multivalent-ion batteries due to their potential applications in large-scale energy storage systems. Here we report a prototype of rocking-chair ZIB system employing Zn2Mo6S8 (zinc Chevrel phase) as an anode operating at 0.35 V, and K0.02(H2O)0.22Zn2.94[Fe(CN)6]2 (rhombohedral zinc Prussian-blue analogue) as a cathode operating at 1.75 V (vs. Zn/Zn2+) in ZnSO4 aqueous electrolyte. This type of cell has a benefit due to its intrinsic zinc-dendrite-free nature. The cell is designed to be positive-limited with a capacity of 62.3 mAh g−1. The full-cell shows a reversible cycle with an average discharge cell voltage of ~1.40 V, demonstrating a successful rocking-chair zinc-ion battery system.
