“…Another mixture of propylene carbonate (PC) and water containing Ca(CF 3 SO 3 ) 2 also improved the electrochemical performance of PBAs. [ 52 ] PC served as a role in reducing the number of water molecules solvating Ca 2+ without directly participating in solvation, and the amount of PC had a great influence on the electrochemical performance. The small amount of water that induces a shielding effect and the large number of organic solvents that weakly interact with Ca 2+ contributed to the high performance of CuHCF.…”

In the post‐lithium‐ion battery era, calcium‐ion batteries (CIBs) have aroused extensive attention because of their strong cost competitiveness, low standard redox potentials, and high safety. However, the related research is progressing slowly due to the constraints of the development of electrode materials. The large ionic radius of Ca2+ especially increases the challenge to design cathode materials for reversible Ca2+ uptake/removal. Despite the inspiring achievements, various challenges still need to be further resolved. Here, this review systematically summarizes the recent advances in CIB cathode materials, including Prussian blue and its analogues, metal oxides, metal chalcogenides, polyanionic compounds, and organic materials. We first provide a brief introduction to CIBs and compare their advantages with other battery technologies. Then, preparation methods are introduced, and breakthrough investigations are highlighted. Finally, some possible research directions are discussed to promote the development of this emerging battery technology.

Rechargeable batteries based on multivalent chemistry represent a promising avenue in grid-scale and portable energy storage devices, especially when multivalent metal with high energy density is used as the anode. Owing to the unique advantages of large 3D diffusion channels, multiple oxidation states of metal ions, and the ability to modulate the size of the intercalation channels for multivalent ions (Zn2+, Mg2+, Al2+, Ca2+) intercalation/deintercalation, open framework materials are regarded as ideal cathodes. Herein, this review firstly provides an introduction of recent open-framework structure based cathode materials including Prussian blue and its analogs (PB/PBAs), NASICONs, Zinc vanadate (zinc pyrovanadate, e.g., Zn3V2O7(OH)2·2H2O and α-Zn2V2O7, zinc n-vanadate, e.g., Zn(OH)VO4), and Molybdenum-vanadium oxide (Mo2.5+yVO9+z) along with a presentation of their energy storage mechanisms. Afterwards, representative examples of such intercalated materials applied to multivalent ion batteries are considered. Some strategies to further improve the electrochemical performances of open-framework structure based cathode materials are also presented. Finally, the challenges and development directions of these materials in rechargeable multivalent ion battery systems are discussed.

“…Research into calcium-ion batteries (CIBs), which utilize the redox reaction of calcium ions as an electrode process in secondary batteries, has gained significant momentum recently [1][2][3][4]. These batteries offer a promising alternative that could complement and diversify the energy storage landscape [5][6][7][8][9]. Calcium, being relatively abundant and cost-effective compared to certain other metals used in battery technologies, holds the potential to contribute to more sustainable and cost-efficient battery production.…”

“…The choice between organic and aqueous electrolytes depends on specific battery application requirements, encompassing energy density, power output, safety considerations, and the environmental impact. Organic electrolytes offer higher energy densities and broader voltage windows [2,5,8], while aqueous electrolytes provide enhanced safety and environmental benefits [2,3,5,7,10]. Each type of electrolyte has its advantages and disadvantages, and the selection depends on the trade-offs acceptable for the particular battery system being developed.…”

This study explores the potential of titanium disulfide (TiS2) as an active material for aqueous calcium-ion batteries (CIBs). We investigate the electrochemical redox reactions of calcium ions within TiS2 and assess its suitability for use in aqueous CIBs. Additionally, we examine the impact of varying electrolyte concentrations, ranging from 1.0 to 8.0 mol dm−3, on TiS2 electrode reactions. Our findings reveal that TiS2 exhibits distinct charge–discharge behaviors in various aqueous calcium-ion electrolytes. Notably, at higher electrolyte concentrations, TiS2 effectively suppresses the hydrogen generation reaction caused by water decomposition. In situ X-ray diffraction analysis confirms the intercalation of Ca2+ ions between the TiS2 layers during charging, which is a groundbreaking discovery, signifying TiS2’s applicability in aqueous CIBs. X-ray photoelectron spectroscopy analysis further supports the formation of a solid electrolyte interphase (SEI) on the TiS2 electrode surface, contributing to the suppression of electrolyte decomposition reactions. Furthermore, we investigate the influence of anions in the electrolyte on charge–discharge behavior. Our findings suggest that the choice of anion coordinated with Ca2+ ions affects the SEI formation and cycling performance. Understanding the role of anions in SEI formation is crucial for optimizing aqueous CIBs. In conclusion, this research underscores TiS2’s potential as an active material for aqueous calcium-ion batteries and emphasizes the importance of the electrolyte composition in influencing SEI formation and battery performance, contributing to sustainable and efficient energy storage technologies.
