Abstract

Electrochemical energy storage is flexible and efficient, and it is an important direction for the development of large-scale power energy storage technology. Liquid metal battery (LMB) uses liquid metals and molten inorganic salts as electrodes and electrolytes, respectively, to fundamentally avoid the life-limiting problem of traditional batteries. LMB has the advantages of long life, low cost, and large capacity, and has broad application prospects in the field of power system energy storage. This paper mainly introduced the working principle of LMB, focused on its development history and important research progress, and pointed out the limitations and challenges of existing battery systems. On this basis, the key development directions of LMB were discussed and clarified.

Abstract

As a potential material to solve rampant dendrites and hydrogen evolution reaction (HER) problem of aqueous zinc metal batteries (AZMB), hydrogel electrolytes usually require additional additives or multi‐molecular network strategies to solve existing problems of ionic conductivity, mechanical properties and interface stability. However, the intrinsic zincophilic properties of the gel itself are widely neglected leading to the addition of additional molecules and the complexity of the preparation process. In this work, we innovatively utilize the characteristics of acrylamide's high zincophilic group density, activating the intrinsic zincophilic properties of PAM gel through a simple concentration control strategy which reconstructs a novel zinc‐electrolyte interface different from conventional PAM electrolyte. The activated novel gel electrolyte with intrinsic zincophilic properties has high ionic conductivity and effectively suppresses water activity, thereby inhibiting HER corrosion. Meanwhile, it induces uniform deposition of (002) crystal planes, leading to excellent deposition kinetics and long cycle life, thereby ensuring high interfacial stability. Compared with conventional PAM gel electrolytes, the activated zincophilic group‐rich hydrogel maintained excellent cycling stability (1 mA/cm2, 1 mAh/cm2) over 2250 hours; The Zn//MnO₂ coin cell using novel zincophilic group ‐rich hydrogel still retains a high specific capacity of more than 170 mAh/g at 0.5 A/g after 1000 cycles.

39. Dualism of Remarkable Magnesium Ion Conduction with Low Activation Energy over a Wide Temperature Range versus Limited Stability of the Hybrid Composite Electrolyte Mg‐MOF‐74/MgX2/Propylene Carbonate.

Abstract

A metal–organic framework (MOF) quasi‐solid‐state Mg2+‐ion conductor is prepared with a conductivity of 0.6 × 10−4 S cm−1 already at room temperature. Mg‐MOF‐74 acts as host for MgX2 (X = Cl−, Br−, BF4−) dissolved in propylene carbonate, leading to dry free‐flowing powders with liquid electrolyte exhibiting low activation energy of 0.2 eV with Arrhenius‐type behavior (233–333 K). Different halides and pseudohalides reveal an influence of the anions on ionic conductivity, activation energy, and chemical stability. High transference numbers 0.45–0.80 for Mg2+ ions are recorded, being among the highest reported with small and low‐cost halides. Against magnesium, an insulating solid electrolyte interface layer forms that prevents a steady‐state and full‐MOF decomposition, as shown by powder X‐ray diffraction, FTIR, and Raman spectroscopy. Comparison with pure propylene carbonate shows that the electrolyte is enhanced by MOF addition. Computational studies using density functional theory (DFT) calculations of complexes in solution indicate correlations between the activation energy for Mg2+ migration through the MOF and the Gibbs energy needed to form charged Mg compounds in solution. Furthermore, DFT calculations of complexes within the MOF pore reveal variations in binding energy and charge transfer correlating with experimental transference numbers. Altogether, the high potential of MOFs for quasi‐solid‐state electrolytes with multivalent cations stability issues are illuminated. [ABSTRACT FROM AUTHOR]
