“…To the best of our knowledge, the high reversible specific capacity, rate capacity, and cycling stability of these CVO nanoribbons compare positively with previously reported materials for aqueous Ca-ion batteries (see ) such as K 0.31 MnO 2 ·0.25H 2 O [12] and K 0.3 CuHCF [13].…”

“…For instance, Sun et al report the simultaneous H + and Zn 2+ insertion/deinsertion reactions at the positive electrode of an aqueous Zn-MnO 2 battery [31]. Hyoung et al studied K 0.31 MnO 2 ·0.25H 2 O as a cathode material in aqueous Ca-ion batteries [12]. They confirmed that Ca 2+ was the main contributor to the electrochemical reaction while hydronium ions were also proposed to cointercalate during the reaction [12].…”

“…This problem remained unsolved until very recently when Wang et al used Ca 7 Sn 6 alloy to replace Ca metal as anode, but the cycling stability and coulombic efficiency are still waiting to be improved [11]. Differently from organic Ca-metal batteries, there is more success on the development of Ca-ion batteries where host materials such as organic polyimide can be used as the anode [4]; also, several materials such as K 0.31 MnO 2 ·0.25H 2 O [12], Prussian blue analog copper hexacyanoferrate [13], or CaCo 2 O 4 [14] have been proposed as cathodes for reversible Ca 2+ (de)intercalation for aqueous Ca-ion batteries. We believe that the development of Ca-ion batteries would play a critical role in pushing the Ca-metal batteries forward.…”

Recently, multivalent aqueous calcium-ion batteries (CIBs) have attracted considerable attention as a possible alternative to Li-ion batteries. However, traditional Ca-ion storage materials show either limited rate capabilities and poor cycle life or insufficient specific capacity. Here, we tackle these limitations by exploring materials having a large interlayer distance to achieve decent specific capacities and one-dimensional architecture with adequate Ca-ion passages that enable rapid reversible (de)intercalation processes. In this work, we report the high-yield, rapid, and low-cost synthesis of 1D metal oxides MV3O8 (M=Li, K), CaV2O6, and CaV6O16·7H2O (CVO) via a molten salt method. Firstly, using 1D CVO as electrode materials, we show high capacity 205 mA h g-1, long cycle life (>97% capacity retention after 200 cycles at 3.0 C), and high-rate performance (117 mA h g-1 at 12 C) for Ca-ion (de)intercalation. This work represents a step forward for the development of the molten salt method to synthesize nanomaterials and to help pave the way for the future growth of Ca-ion batteries.

Preintercalation Strategy in Manganese Oxides for Electrochemical Energy Storage: Review and Prospects

et al. 2020

View full text Add to dashboard Cite

the past decades, some issues of MnO 2based cathodes still remain due to the low electronic conductivity, [19-21] low utilization of reversible discharge depth, [22,23] sluggish diffusion kinetics, [24-26] and poor structural stability upon cycling, [27-29] which restricts their practical application in the commercial secondary batteries. Taking the Zn-ion batteries as example, the MnO 2 cathode seriously suffer from the above issues, especially the sluggish Zn 2+ diffusion, [30] and structural collapse issue during H + /Zn 2+ intercalation/ extraction cycles. [31-33] Regarding these bottlenecks, researchers have strived to develop strategies that can realize optimizations in capacity, rate, and cycling properties of MnO 2 cathodes, such as surface coating, [34] metal-doping, [35] preintercalation, [36] etc. Among all the strategies, preintercalation strategy provides a basic and effective method for optimizing the structure and electrochemical performance of MnO 2-based cathodes. In recent years, the preintercalation strategy has attracted much attention as an effective approach to enhance the electrochemical performance of cathode materials, including vanadate, [37] manganese oxides, [23] layered LiCoO 2 , [38] etc. Several reviews and prospects have been conducted for MnO 2 materials. Some reviews have mentioned the electrochemical properties and correlated reaction mechanism of MnO 2 materials in aqueous Zn batteries, [29,39,40] and a review by Mai's group offers insights into the rational design of preintercalation electrodes in next-generation rechargeable batteries. [36] However, a review or prospect on the application and mechanism of the preintercalation strategy in MnO 2 materials for nextgeneration batteries is lacking. For MnO 2 electrode materials, many reports on improving the electrochemical properties of materials by applying preintercalation strategy have been emerged in the last 5 years (Table S1 in the Supporting Information). The main feature of the preintercalated MnO 2 materials is that some ions/molecules are preintercalated into the tunnel or interlayer hosts of MnO 2 materials prior to the battery cycling (or during synthesis process). These intercalated guest species, including ions, inorganic/organic molecules, as well as polymers, present electrostatic and physical interactions with the host framework and the inserted carrier ions via chemical bonding or coordination, presenting significant benefiting effect on the inherent structure of hosts and the transport kinetics of carrier ions. Generally, there are several Manganese oxides (MnO 2) are promising cathode materials for various kinds of battery applications, including Li-ion, Na-ion, Mg-ion, and Zn-ion batteries, etc., due to their low-cost and high-capacity. However, the practical application of MnO 2 cathodes has been restricted by some critical issues including low electronic conductivity, low utilization of discharge depth, sluggish diffusion kinetics, and structural instability upon cycling. Preintercalation of ions/molecules ...

The article is devoted to the evolution of structural, morphological, and sorption characteristics of layered manganese oxide (birnessite) under various conditions close to the real operating regime of the sorbents for radioactive waste processing. To identify the phase composition in the birnessites, we implemented XRD analysis, while SEM and temperature-programmed reduction (TPR) were used to study morphological and redox features of the materials, respectively. Structural changes after various kinds of treatment of birnessites were tracked using low temperature nitrogen sorption. Sorption characteristics were assessed under static and in dynamic conditions on the efficiency of Sr2+ removal from simulated seawater. TPR combined with kinetic analysis revealed the decrease of particle sizes in the birnessites after repeated use in sorption-regeneration cycle and reduction with hydrazine. Despite the fact that the porous structure of the materials remains preserved, the surface morphology of birnessite changes drastically depending on the reducing agent. Hydrazine treatment increases the sorption performance of the birnessite followed by degradation of mechanical properties, thus, preventing such sorbent from repeated use. Kinetic analysis of TPR allows quantifying differences in morphology and porous structure of manganese oxide materials. The specific surface area, amorphous surface structure, and accessibility of Mn+3 sites are the most important factors for birnessite sorption performance.
