Abstract
The invention provides compound ionic liquid and a preparation method thereof. The compound ionic liquid is prepared form raw materials including, by mass, 1-3 parts of choline chloride, 1-6 parts of urea, 1-4 parts of N,N'-dialkylimidazolium and 1-4 parts of 1-allyl-3-methylimidazole. According to the preparation method, the raw materials are weighed in proportion and then mixed in a dry beaker; the raw materials are put into a water bath kettle of 85 DEG C and are subjected to magnetic stirring until the raw materials are dissolved completely to form colorless and transparent thick ionic liquid finally. The compound ionic liquid provided by the invention has the advantages that a potential window is wide, the steam pressure is low; the thermal stability is good; the compound ionic liquid is nonflammable, high in ionic conductivity and wide in liquid-state temperature range when used for metal electrodeposition.
