A double-center quaternary ammonium salt ion liquid having the structural formula (I), wherein n=2, 3 or 6, Yis BF, PF, (FSO)N, (CFSO)Nor CFS. Also provided is a method for preparing a double-center quaternary ammonium salt ion liquid. The double-center quaternary ammonium salt ion liquid has high stability, and thus an electrolyte containing the double center quaternary ammonium salt ion liquid has a high decomposition voltage. 

Double-center quaternary ammonium salt ion liquid, preparation method therefor and use thereof

Disclosed is a double-center bipyridyl cationic ion liquid prepared by reacting bipyridyl with haloalkane for synthesis of dialkyl bipyridyl halide, and converting the halogen ion in the dialkyl bipyridyl halide to the target anion via an ion-exchange reaction, to give the final target ionic liquid. Also disclosed are an organic electrolyte containing the double-center bipyridyl cationic ion liquid and a preparation method therefor.

Double-center bipyridyl cationic ion liquid, preparation method therefor and use thereof

A fluorographene and preparation method thereof are provided. For the said fluorographene, the fraction of F is 0.5&#x3c;F %&#x3c;53.5% in weight and the fraction of C is 46.5%&#x3c;C %&#x3c;99.5% in weight. The method comprises the following steps: providing the graphite; preparing the graphene oxide with the graphite; mixing the graphene oxide with the compound containing fluorine by weight ratio of 1:1&#x2dc;100:1 in anaerobic environment, reacting at 200&#x2dc;1 000&#xb0; C. for 1&#x2dc;10 hours then cooling down to obtain the said fluorographene. The above-mentioned method using graphite to prepare the graphene oxide, then making use of the reaction of graphene oxide with the compound containing fluorine under a certain temperature has simple process and can prepare fluorographene conveniently.

Fluorographene and preparation method thereof

Provided are a fluorinated graphene oxide and a preparation method thereof. In the fluorinated graphene oxide, the mass percent of fluorine is 0.5%&#x3c;F %&#x3c;40%; the mass percent of carbon is 50%&#x3c;C %&#x3c;80%, and the mass percent of oxygen is 0.5%&#x3c;O %&#x3c;30%. The preparation method comprises the following steps: providing graphite; preparing graphene oxide by using the graphite; and subjecting the graphene oxide to reacting with a mixed gas of Nand Fat 20&#x2dc;200&#xb0; C. for 0.5&#x2dc;24 h, to prepare the fluorinated graphene oxide. The preparation method is simple, has fewer steps, and has better prospect of application.
