“…However, the relative potential disparity of AC reference electrodes from different research groups amounted up to 600 mV, resulting in large redox potential uncertainty even for similar cathode materials.

Ca‐metal batteries, one of the promising advanced energy storage devices, have received significant development in the last few years. However, challenges still exist in efficient and cost‐effective Ca‐metal utilization, fast Ca‐ion transport and diffusion, and high energy density and stable‐cycling Ca‐storage. Herein, by cross‐checking most relevant literature reported previously, an intuitive depiction for state‐of‐the‐art Ca‐metal batteries, including collectors, electrolytes, and cathode materials, is presented from a voltage‐capacity‐efficiency's view, which facilitates reasonable comparisons from related fields. The performance of most cathode materials and calcium‐metal electrodes in various electrolytes reported previously is comprehensively reviewed, as well as interphases and collectors. The strong and weak points of various electrolytes are discussed, and relevant challenges are pointed out. Recent breakthroughs in electrolyte and interphase engineering are emphasized. Finally, potential development directions for Ca‐metal and electrolytes, as well as some future prospects for cathode materials, are rationally predicted.

“…The average discharge voltage was about 2.6 V v Ca/Ca 2+ , with the potential of the AC electrode being 3.08 V vs. Ca/Ca 2+ (Figures 2d, S and S6). This reversible capacity (303 mAh g −1 ) is the highest among those reported: Pru sian-blue analogues (50-120 mAh g −1 ) [10-14], NaFePO4F (~80 mAh g −1 ) [16], CaxMoO (~100 mAh g −1 ) [19], Mg0.25V2O5•H2O (~110 mAh g −1 ) [23], VOPO4•2H2O (~100 mAh g −1 ) [24 NaV2(PO4)3 (70-80 mAh g −1 ) [25,26], and Ca0.13MoO3•(H2O)0.41 (~190 mAh g −1 ) [27].…”

“…In addition, no promising cathode materials have been developed yet, probably because of a lack of understanding regarding the unique calcium intercalation chemistry, despite the extensive research, including theoretical/computational studies [3]. The calcium-insertion materials in nonaqueous electrolytes reported so far include Prussian-blue analogues [10][11][12][13][14], CaCo 2 O 4 [15], NaFePO 4 F [16], NH 4 V 4 O 10 [17], α-MoO 3 [18], Ca x MoO 3 [19], TiS 2 [20], α-V 2 O 5 [21], CaMnO 3 [22], Mg 0.25 [24], NaV 2 (PO 4 ) 3 [25,26], and Ca 0.13 MoO 3 •(H 2 O) 0.41 [27]. Most of these materials exhibit low Coulombic efficiency, capacity, or cyclability in dried nonaqueous electrolytes.…”

Calcium-ion batteries represent a promising alternative to the current lithium-ion batteries. Nevertheless, calcium-ion intercalating materials in nonaqueous electrolytes are scarce, probably due to the difficulties in finding suitable host materials. Considering that research into calcium-ion batteries is in its infancy, discovering and characterizing new host materials would be critical to further development. Here, we demonstrate FeV3O9∙1.2H2O as a high-performance calcium-ion battery cathode material that delivers a reversible discharge capacity of 303 mAh g−1 with a good cycling stability and an average discharge voltage of ~2.6 V (vs. Ca/Ca2+). The material was synthesized via a facile co-precipitation method. Its reversible capacity is the highest among calcium-ion battery materials, and it is the first example of a material with a capacity much larger than that of conventional lithium-ion battery cathode materials. Bulk intercalation of calcium into the host lattice contributed predominantly to the total capacity at a lower rate, but became comparable to that due to surface adsorption at a higher rate. This stimulating discovery will lead to the development of new strategies for obtaining high energy density calcium-ion batteries.

“…Recently, NASICON structured materials (NaV2(PO4)3 33,34 , CaxNa0.5VPO4.8F0.7 35 ) have been explored for Ca storage, because the ionic size of Na is very close to that of Ca (~1 Å). However, the aforementioned materials either lack high specific capacity, high-rate performance, or cyclic stability.…”

Looming concerns regarding scarcity, high prices and safety threatens the long-term use of lithium in energy storage devices. Calcium has been explored in batteries because of its abundance and low-cost, but the larger size and higher charge density of calcium-ions relative to lithium impairs diffusion kinetics and cyclic stability. In this work, an aqueous calcium-ion battery is demonstrated using orthorhombic, trigonal and tetragonal polymorphs of molybdenum vanadium oxide (MoVO) as a host for calcium ions. Orthorhombic and trigonal MoVO outperforms the tetragonal structure because large hexagonal and heptagonal tunnels are ubiquitous in such crystals, providing facile pathways for calcium diffusion. For trigonal MoVO, a specific capacity of ~203 mAh g-1 was obtained at ~0.2C and at 100 times faster rate of ~20C, ~60 mAh g-1 capacity was achieved. The open-tunnel trigonal and orthorhombic polymorphs also promote cyclic stability and reversibility, showing a capacity fade rate of ~0.15% per cycle. A review of the literature indicates that MoVO provides one of the best performances reported to date for the storage of calcium.
