Explosive though stable: Dicyanoborate‐based ionicliquids are hypergolic fuels in the presence of white fuming nitric acid as oxidizer (see high‐speed picture of the ignition process). With long liquid ranges, low viscosities, and short ignition delay times, these thermally and hydrolytically stable ionicliquids appear to be very promising substitutes for hydrazine and its derivatives as bipropellants
investigated as an additive to an ethylmagnesiumbromideGrignard solution, for use as an advanced electrolyte in rechargeable Mg batteries. Electrochemical studies showed that the addition of the ionic liquid significantly enhanced the anodic limit of the Grignard solution by about 1 V and improved the coulombic efficiency and the kinetics of Mg deposition-stripping reactions on the negative electrode.

研究了离子液体1-烯丙基-1-甲基吡咯烷鎓氯化物作为乙基溴化镁格利雅(Grignard)溶液的添加剂,用作可再充电镁电池中的高级电解质。电化学研究表明,离子液体的添加显着提高了格氏溶液的阳极极限约1 V,并改善了库仑效率和负极上Mg沉积-剥离反应的动力学。我们还证明了含有离子液体的格氏溶液在由Mo 6 S 8 Chevrel相阴极和Mg金属阳极组成的原型电池中可以很好地用作电解质,而原来的格氏电解质不能正常运行。
