Deep eutectic solvents (DES) composed of lithium, sodium, or potassium iodide salts in suitable combination with ethylene glycol (EG), glycerol (Gly), or polyethylene glycol (PEG) have been developed. All prepared DES were characterized by thermal analysis (DSC and TGA) and its complex conductivity (σ*) and impedance (Z*) frequency were evaluated through dielectric relaxation spectroscopy (DRS). Two- and three-electrode electrochemical studies of all DES have been performed. All DES avoid crystallization, exhibiting conductivity values in a range from 10^–4 to 10^–2 S cm^–1 at room temperature and electrochemical windows higher than 1 V (on the order of 3–4 V), fulfilling the usual suitability criteria for utilization in electrochromic devices (ECD). The most promissory DES as electrolytes were tested for ECD. Being suitable candidates for further application in batteries.

碱性碘化物基深共溶剂的电化学应用

已经开发了由碘化锂，钠或钾的盐与乙二醇（EG），甘油（Gly）或聚乙二醇（PEG）适当组合而成的深共熔溶剂（DES）。通过热分析（DSC和TGA）对所有制备的DES进行表征，并通过介电弛豫谱（DRS）评估其复电导率（σ*）和阻抗（Z *）频率。已对所有DES进行了两电极和三电极电化学研究。所有DES均避免结晶，其电导率值介于10 ^–4到10 ^–2 S cm ^–1之间在室温下和高于1 V（3-4 V数量级）的电化学窗口下，符合用于电致变色器件（ECD）的通常适用性标准。测试了作为电解质的最有效的DES的ECD。是进一步在电池中应用的合适候选人。
