“…Moreover, the use of organic compounds as electrode materials is also promising . Using charge carriers other than Li ions, such as sodium, potassium, magnesium, calcium, aluminum, or molecular ions, is another method to develop sustainability in society. The development of systems that are completely free of scarce metal elements, including a scarce metal‐free charge carrier, will have a significant impact in a society that is heavily dependent on electricity and its consumption.…”

“…So far, no vanadate has been reported in aqueous Ca-ion batteries, which indicates that there might be a lot of interesting vanadium-based electrode materials remaining to be discovered for Ca-ion batteries. For organic Ca-ion batteries, only V 2 O 5 has been reported as the cathode material, but the reversible capacity drops down to only 20% after only 4 cycles [21, 22]. Among the vanadium-based oxides, metahewettite-type CaV 6 O 16 ·3H 2 O has been reported as a possible cathode material for Li-ion [23] and Zn-ion batteries [24].…”

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.

The urgent demand for cost‐effective energy storage devices for large‐scale applications has led to the development of several beyond‐lithium energy storage systems (EESs). Among them, calcium‐ion batteries (CIBs) are attractive due to abundant calcium resources, excellent volumetric and gravimetric capacities of Ca metal anode, and potential high energy density coming from the multivalent feature of Ca‐ion. Therefore, the exploration of CIBs electrode materials and the construction of CIBs devices are gaining increasing research interest. Relevant publications cover a wide range of materials by both theoretical and experimental investigations, whereas the performances of rocking‐chair CIBs have been unsatisfactory. Meanwhile, multi‐ion strategies using more than one ion as the charge carrier have been demonstrated to be feasible and promising options in realizing room temperature CIBs. The summary and reflection of previous studies would provide useful information for future exploration and optimization. In this circumstance, this paper overviews the reported CIBs electrode materials, including both anode and cathode, and presents the latest progress of multi‐ion strategies in CIBs. Fundamental challenges, potential solutions, and opportunities are accordingly proposed, mimicking other more mature EESs. This review may promote the development of electrode materials and accelerate the construction of low‐cost and high‐performance CIBs.
