Substituent Effect of Imidazolium Ionic Liquid: A Potential Strategy for High Coulombic Efficiency Al Battery was written by Yang, Congrong;Wang, Suli;Zhang, Xiaoming;Zhang, Qiang;Ma, Wenjia;Yu, Shansheng;Sun, Gongquan. And the article was included in Journal of Physical Chemistry C in 2019.Name: 1-Methyl-3-propylimidazolium Chloride This article mentions the following:
The chem. structure-effect relationship between imidazolium ion liquid and the properties of electrolyte or Al battery is first completely revealed. First, it is proved that there indeed exsits an interaction between imidazolium cation and chloroaluminate anions (active ions, Al2Cl7– and AlCl4–), blocking their reaction in the anode or pos. electrode. Second, by introducing the substituent effect, which could enhance the steric hindrance and change the detailed electronic distribution of imidazolium cations, the intermol. force between imidazolium cations and chloroaluminate anions is effectively weakened. As a result, the electrodeposition achievement, electrodeposition/electrostripping reversibility of aluminum, and intercalation/deintercalation capacity of AlCl4– in the pos. electrode are significantly improved. Therefore, the as-assembled battery with AlCl3/[MPIM]Cl electrolyte shows an 鈭?00% CE. This work provides a potential approach on how to enhance the performance of Al battery by designing the ionic liquid structure. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Name: 1-Methyl-3-propylimidazolium Chloride).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Name: 1-Methyl-3-propylimidazolium Chloride
