This work investigates the electrochemical intercalation of Ca²⁺ ions into TiS₂ in organic electrolytes at room temperature and demonstrates that successful intercalation/de-intercalation can be achieved using a 0.1 M solution of Ca(CF₃SO₃)₂ in propylene carbonate (PC) as an electrolyte. Additionally, further performance (charge/discharge capacity, reversibility, and hysteresis) enhancement is observed when a 0.1 M solution of Ca(CF₃SO₃)₂ in a 1:10 (mol/mol) mixture of PC and dimethyl carbonate (DMC) is employed, which is ascribed to the modulation of the solvation environment of Ca²⁺ ions by the use of the relatively low-polar DMC. Finally, the structural changes in TiS₂ caused by Ca²⁺ intercalation/de-intercalation during charge/discharge are probed by in situ X-ray diffraction analysis.

这项工作研究了室温下有机电解质中Ca ²⁺离子在TiS ₂中的电化学嵌入，并证明了使用0.1 M Ca（CF ₃ SO ₃）₂在碳酸亚丙酯（ PC）作为电解质。此外，当在PC和碳酸二甲酯（DMC）的1:10（mol / mol）混合物中加入0.1 M Ca（CF ₃ SO ₃）₂溶液时，可以观察到进一步的性能（充电/放电容量，可逆性和滞后性）增强。）的使用，这归因于Ca ²⁺的溶剂化环境的调节通过使用相对低极性的DMC离子。最后，通过原位X射线衍射分析探明了由Ca ²⁺嵌入/脱嵌在充电/放电过程中引起的TiS ₂的结构变化。
