- ELECTROLYTE SALTS FOR RECHARGEABLE MAGNESIUM-ION BATTERIES
-
Magnesium salts suitable for use in an electrolyte for a magnesium ion electrochemical cell are described herein. The salts are magnesium tetra(perfluoroalkoxy)metalates, optionally solvated with up to seven ether molecules coordinated to the magnesium ion thereof. In one embodiment, the salt has the empirical formula: Mg(Z)22+[M(OCR3)4?]2 (Formula (I)) wherein Z is an ether; n is 0 to about 7; M is Al or B; and each R independently is a perfluoroalkyl group (e.g., C1 to C10 perfluoroalkyl). The magnesium salts of Formula (I) are suitable for use as electrolyte salts for magnesium ion batteries (e.g., 5 V class magnesium batteries) and exhibit a wide redox window that is particularly compatible with magnesium anode. The salts are relatively cost effective to prepare by methods described herein, which are conveniently scalable to levels suitable for commercial production.

- Preparation method and application of silver auxiliary
-
The invention relates to a method for preparing a silver auxiliary AgAl(ORF)4. The method comprises the following steps that 1, HORF reacts with LiAlH4 to generate a lithium-aluminum compound LiAl(ORF)4; 2, the lithium-aluminum compound LiAl(ORF)4 obtained in the step 1 reacts with AgBF4 to generate a compound AgAl(ORF)4, wherein RF is a C1-C5 hydrocarbyl group, and hydrogen atoms on the hydrocarbyl group are optionally replaced with fluorine atoms. The invention further relates to application of the silver auxiliary in an ethylene tetramerization technology. The preparation method is simple, 1-octene can be highly selectively produced when the silver auxiliary is applied in ethylene tetramerization, and the selectivity of 1-octene is higher than 60%.
